3ds Max :: Final Gather Process Halting In Recalculation
May 26, 2011
I've got a scene set up with a lot of objects (about 680 of them), and about a million polys. I'm in the process of trying to render out the animation and I'm running into some problems.
When I am attempting to recalculate my final gather maps so I can interpolate between frames and reduce flicker in the final animation, it is halting at different frames depending on what final gather settings I'm using, but halting with every setting I've tried.
This last time I tried it with "Low" default settings (.4, 150, 30, 0 bounces) and it stopped on frame 90 at 99.9% of "computing final gather points". With other settings it has stopped at frame 102 at 95.4%, and on another setting frame 87 at 66.5%. The most common percentage to halt at has been 99.9% of Computing Final Gather Points, but the frame number it halts on and the percentage varies.
The halt is repeatable and happens at the same exact spot in the animation depending on the settings. So if I use "Low" (.4, 150, 30, 0) it will always stop at frame 90 at 99.9% Computing Final Gather Points. The other settings will produce the same result over and over as well. I also attempted to re-start the precalculation from the frame that it halted on (after deleting the previous FGM file for that frame). Frame 90 still halts at 99.9%... or frame 102 halts at 95.4%... etc...
I can, however, get frame 91 to complete it's final gather map if I set the sequence to pick up on the next frame and go from there.I will attach an image of the model/scene I'm currently working on.
I'm trying to optimize the rendering time on pre-rendering my Final Gather map.
I've set it to every 5 frames and halved the resolution of my FG map compared to the final render but I'm wondering if some of the other roll-outs such as the Image Precision, Soft Shadows, Glossy Reflections and Refractions make a difference to the FG map. Can I knock these settings down a notch or two, or do I have to keep them the same as the final render?
After I installed design 2011 student version, I can't move the final gather presets or for that matter there are no presets available to change. And the values go erratic often. I switched to scanline and back to MR but that doesn't rectify it.
And also there are no geographic locations available in my daylight system
I am working with a network and it works for standard rendering.
I want to use it to pre-generate the FG maps. I have tried the "generate now" button, but that makes the FG calculate locally on the current machine... even with Net render checked.
When I try doing a render using the frames just as junk, it renders out, but does not save the FG map.
If I generated FG maps with interpolation of every 3 frames and I use read FG points at every 2 frames. Would this be wasting my time? Would it be better if I just set it to 0? Once it starts rendering it comes up with warning signs saying it can't find specific FG maps which is understandable. Would max have to generate new ones (because this would be a waste of render time) and if it does can I somehow just tell it not to?
It is an animation that I am rendering (moving car and moving camera).
Max 2013 now can't read or write final gather maps. I get an error cannot open map file. I have tried using a unc path \server name. I had the problem previously whan I moved to win 7 and I got around it by turning off my UAC. But that is off.
I am trying to write a layer gathering and changing program that will store a lists of layers based on layers they need to be changed to. I am writing it in C# and the part that is killing me is I need to store the old layers before I convert them so that way in the future the program will automatically know to change those layers to the appropriate layer.
I am trying to use an .xml file to permanently store the layers, and a serializer to read the layers into a dictionary so that I can search and see if I have already come across a layer.
I know that sounds very convoluted so let me simplify the problem. We have our layers which are only 7 layers. We get drawings from outside sources and they have their layers. Their layers correspond to one our 7 layers. We have a list showing which of their layers correspond to one of our layers. When we get drawings with layers we've never seen before, we need to search through the list to confirm it isn't already there and if it is not present, then ask the user to which of our layers their new layer should be associated.
I want to store the data in a xml file in a manner similar to this <ourlayertheirlayer> ourlayer1, somerandomthintg ourlayer1, anotherrandomthing ourlayer1, thisrandomthing ourlayer2, whatisthis ourlayer2, whoisthis ourlayer3, whycantifigurethisout ourlayer3, canyoufigureitout</ourlayertheirlayer>
Then I want to serialize the xml file and save the data in a Dictionary<string,string> type whre the first string is one of our layers and the second string is their layer.
I want the data in the xml file to persist between application sessions, but the dictionary would be filled each the program is started.Later in the program I will use the Dictionary to gather all the objects based on their layer, the second string in the dictionary, and convert them to our corresponding layer, the first string in the dictionary.
I am having trouble setting up my types in C# though. How do I create an xml serializer that will read ourlayer, theirlayer from an xml file and save it to a Dictionary. The data doesn't have to be in the xml file in that format either, I just can't think of an easier way than commas to sepearte the two pieces of data.
public class OursTheirs{ public List<string>[,] goToDict { get; set; }}public class oursTheirsComma{ public string commaPresent { get; set; }}public static class SerializeAddToDict{ public static string getFromXML(string xml) { XmlSerializer xmls = new XMLSerializer(typeof(string)); return xmls.Deserialize(new StringReader(xml)) as string; } public static List<string>[,] ParseXML { //Stuff here
I haven't figured out to convert the string to a //List<string>[,] where the first column is one of our 7 layers,second //column their layer } //Then some other stuff here to add the stuff to a dictionary}
How the PMS color palettes "simulate" on screen how the color will print on different substrates (glossy vs matte vs uncoated paper). That's great for comps, but if you convert it to CMYK to print it, and the values are representing a "simulated" color it won't look correct (by that I mean come close to matching the spot color). For example, the uncoated palette simulates the color by making them appear a bit washed out on screen - pretty good visual simulation. But it might do so by adding black and cyan to orange for example, etc. - effectively dulling the original color.
So if I convert that to CMYK within the new Pantone + color palette, and then send it to the printer - it won't appear as it did on screen, it will dull the end color even more because it's converted the color to the dull simulated version - what a disaster! It's only doing half the job - showing us what it should look like on screen. In order to be truly efficient for design professionals the CMYK conversion might remove black and cyan completely to effectively brighten the color in the final output on uncoated paper. I would prefer it just stick to the standard conversion, which Pantone did have as a standard palette option (PMS to process), and then I can adjust if I think it's necessary.
Any corporate branding system will likely start with a PMS spot color palette for the identity. Then it will build into many different adaptations - full color brochures, large format banners and trade show graphics, website, advertising. So any corporate branding system will need to have PMS, CMYK and RGB versions of their main corporate color palette. There was a standard for these translations that was automatically consistent in the Adobe software and that is now all over the place, so it relies on individuals manually adapting the color mixes for final use - what a great way to screw things up.
I am new to PS scripting and trying to create a basic script to gather folder paths and then remove the path of that folder. I have created a basic array and while trying to
I am just starting to learn C# and .NET and I am trying to write a simple program to gather all the layers from a drawing in a directory, save them to a list, and use that list to change those layers to the appropriate layers. The way I want it to iterate is open the first drawing, gather the layers, ask the user which layer they want to change the original layer to, and when they select the new layer, it associates that old layer with the new layer so that in the future it won't prompt the user, it will just change it to that layer. Then it changes the layers and goes to the next drawing.
I wrote something very simple in LISP, but I need to make it more advanced and try to add in more features. Specifically I would like to be able to do everything in the background, without actually opening the drawings so I can avoid any user prompts or dialogue boxes.
I am at a complete loss at where to start though. There are so many members in the different namespaces for Autocad. Right now I am looking through acdbmgd.dll and acmgd.dll to try and find something useful, but I have no idea where to even start.
My guess would be to first define a method that gathers the layers from the drawing and saves them to an array. For example i would have multiple arrays for the different layers to which I want to convert the old layers, string [] 0layer, string [] walllayer that contains all of the layers to be changed to layer 0 and wall layer. Then I would compare the layers in the drawing to those arrays, if they are not present in any of the arrays, the program would prompt the user and ask which layers they want to change the existing layer to and add it to the appropriate drawing. Then all of the layers in those arrays would be changed to the different new layers.
At the very least, I am going to start making the different arrays to be filled. That much I can do. I'm just having trouble actually getting the data from the drawings.
Any plugin or something that gathers all the colors within a given image and allows you to save the pallete in another image...If you seen a sprite sheet thats pretty much what Im asking for.It'd be cool if the colors were sorted by how dark it was and by RGB.
I created 61, 9 layer composites that are text only, but I can not figure out how to export it with the alphas for use in keying in Final cut. I exported as Targas, psd's and eps's but nothing give me the alpha and I end up with a flat image that I can only to an add key with in Final Cut...this loses all of my shadows and glows, etc......
I have copied an pasted a pdf into model space to show in a viewport for the finished sheet. The pdf appears just like I want it in the viewport and when I do a preview it looks fine. However when I plot the final pdf (dwg to pdf) the viewport is blank. But, the pdf shows up in at leaset one other viewport on the sheet.
I'm using CS5 and beginning to use HDR. When I merge to HDR pro and make adjustments to images the preview window is extremely different from the final image. I'm merging original camera raw images from a Nikon D200. Workflow in ACR is set to 16bit. Output from HDR pro is also 16bit. I adjust using the preview window, but after final processing the resulting image is grossly different, much more saturated and more vibrant among other differences.
I have layers for different possible end picture effects. eg text in different colors some of it on slopes etc. I would like to send the client a few different choices without having to flatten or "merg visible" layers. If I do that then I loose the possibility of changes that the client might want.
I have made a scene in 3ds max design 2013, using all default materials of autodesk and I am rendering using mental ray. the final image rendered in a very good quality has lot of black patches.
I'm trying to model a part (the front sight of a 1911 pistol) and I'm trying to fully constrain my initial sketch manually. I have one final dimension to place, but I can't seem to figure it out. I used the automatic dimension function to insert it, but I can't seem to duplicate it manually.I've attached screenshots showing the sketch before and after the automatic dimension was inserted. It seems the same as the other two vertical dimensions I have in place. I'm using the M1911 Redux drawings located at the following link: URL....
Note, these drawings are not my intellectual property and are being used for personal reasons only.
I downloaded the images from my camera to IPhoto and then 'dragged' them into Lightroom 5. After I have develped them and created a collection, can I save them back to IPhoto to replace the old source file or they just stay in Lightroom permanently?
My director friend has seen me color correct images in LR with grace and skill, and wants me to start doing color correction for his films. I have never used Final Cut Pro before, and wondered if the controls in Final Cut were similar to LR, if you could export and import between the two, and generally what the difference was between working with color in each. He has one of the RED cameras, which shoots in RAW, so I assume the different can't be too great.
I'm editing with RAW RED files straight from camera. Looking good but just want to know what my best possible output file and quality scheme should be.
I want to send out REDlog Film Gamma space for my color session and I've selected that for all my clips but is there any quality debayering setting I should select before output? And to what file extension output? DPX max bit depth? Uncompressed 10-bit?
I've been asked to do a poster A2 size 594mm x 420mm 300dpi but when i enter these dimensions my pc is slowing down dramatically. whats the best way to achieve better performance?
If it's possible to attach File Info such as Copyright to a (final) .png image? I could have sworn that I've done it before but just now it didn't work.
When I do the final render on my project, I find that in certain spots the audio is clicking, kinda sounds like static. It tends to happen when I do hi-def renders, but almost happens all the time. The only time it doesn't seem to happen is when I do low quality rendering. However, when I am editing the project, before I do the final render, there are no audio clicks at all. how to fix it?
I have completed my final part modelling, but as you know that before final machinig the part i want to get it forged from my vendor for that i want to prepare the forging drawing for him. but when i place the base view in the drawing sheet i always get the final part. How to prepare the forging drawing from the final part drawing or is there any way to make it.
I'm making an ad with alot of bright colors. It's gonna be printed to a glossy photo paper for distribution, but I'm having a hard time getting the monitor colors to match the printout colors.
I started as RGB workspace, then once finished I converted to CMYK, but the colors drastically get dull.
I know that it is normal for colors to change during RGB to CMYK transition, but is there any way I can preserve those bright colors?.. (it's mostly bright orange and green.)
