I'm using mental ray rendering photometric lights with a lot of reflective surfaces. I keep getting little white specks showing up on certain surfaces.
View 1 RepliesI've enclosed an original picture and my 3d scene. the problems lies in the shadow on both sides of the lamp which is too hard edged. and normally, there is a grid right beneath the cylinder bulb, but when applying that grid in 3ds max the whole scene becomes speckled. must have something to do with the light being blocked by geometry.
how to achieve a soft shadow as shown in the ref pic?
I have an issue that every time I render a scene with photometric lights and have the exposure control set to Mr. Photographic exposure, outdoor night time, I get flicker. It appears to be an interlacing problem, but looks like the lights are flickering bright and dim. I am rendering as a .jpg sequence.

I can't find any controls that are affecting the shadows or any useful information on the web. I am using mental ray and ray traced shadows.

the nitrous viewport creates correct soft shadow adjustments as I change the width and height of a rectangular light source. the render does NOT.

View 2 Replies View Relatedwe're currently doing an animation of a walkthrough of an airport where we're getting these strange artifacts when rendering after creating the final gather pass.
We're using only mr daylight system to light the scene, to get an all white soft-shadow render. Only three types material, diffuse white, glossy white and glass (all mr A&D). The glossy material gets blown out and we receive strange red and green artifacts here and there in the model.
We use mr Photographic Exposure Control.
I saw something about being able to render faster using network rendering for mental ray, but I'm not sure where I've seen it, nor do I know how it works.
If this is possible it would be great, since a scene I tried rendering had an ETA of about 51 hours. So I turned off ray traced shadows, seems to have lowered the rendering time quite a bit, but I'm still gonna end up with about 26 hours of rendering. If network rendering could bring that time down, that would be great.
Mental Ray Fatal error when rendering
View 3 Replies View RelatedI've got this scene of a roman temple like structure, with the floor being slightly reflective. It is covered in a Volume light completely. When rendered it gives a really nice effect to it, however takes ages to render. And I need it to render faster.
Am rendering it with mental ray, and with the Volume Light deactivated, it takes about 30 seconds to render the whole frame. When activating it rendering less then 1/4th of the frame takes 4:30 minutes.
Now this is not gonna work well when I'm gonna render a movieclip, so I'm gonna ask the following: Is there a good, fast alternative for that volume light?
I cannot get any lights to appear in my 3d scenes until I begin rendering. I have installed all updates. In fact, this started when I installed the Creative Cloud update back in December. Also, how do I get rid of the annoying IBL preset?
View 3 Replies View RelatedI am trying to render using the recessed can lights and they light my rendering but the lights themselves don't look line they are emitting light. It looks odd. I have the same problem with some of my 2x4 fixtures where light does show on the floor but the lights themselves don't seem to be on.

I thought I had this all working. And it did to an extent. When I plug a single displacement map into my standard lambert shader slot in maya, all works fine and dandy. However, as soon as I try to use multiple displacement maps, I am getting the problem that I had in the previous post, which is that the negative values are lost. I sort of understand why this is happening - that is when using a layered shader it uses alpha as luminance, and therefore the values don't go below zero, but I don't know what to do about it!? I have tried a network with set range etc but it just makes a mess. Any straightforward method of using multiple .exr files in a single shader for mental ray in maya?
I am currently using AutoCad 3d 2011 and i am trying to add some graphics (bmp. or jpegs) to surfaces. In model space when materials are on the graphics are there. When i go to render in the graphics come out grey. However if i change the lighting settings to American lighting units the graphics then appear when it is rendered. Why is this? I do not like using American units as it always makes my renders appear washed out.
How graphics can be seen in any of the other lighting units? or why this may be happening?
I'm using inventor studio for the first time(Inventor 2014 / Windows 7). I'm having some trouble with work surfaces showing up in my rendering. The surfaces are set with the visibility turned off. When I'm in my normal assembly window, they're invisible. They're even invisible while im in studio, setting up lights & such. They only show up on my renders. If i go into each part and suppress them they render ok. Problem is I have sketch geometry and constraints that crash when they're suppressed, so I really need them as active, but invisible.
View 3 Replies View RelatedI have a simple model of two desk units. I also have a large rectangular area under them with a carpet texture applied. The desks each have two textures/materials applied. I am rendering to a viewport at 640x480, with shadows on and "high" quality. I have 4 point light sources in the model. When I render to viewport, it all looks great. But when I plot or plot preview, all of the detail/textures/materials in the horizontal surfaces are gone and it plots as completely white in those areas and also shows it white in plot preview.
Attached are two images. RENDER A is a screenshot of the correct image rendered on screen and RENDER B is a screenshot of the plot preview screen showing the white areas (which is also how it really prints).
3ds Max seems to only alow .ies, .cibse and .ltli files as photometric file types - missing out on a huge swath of files - Eulumdat (.ldt) files, a standard used in Europe.
I understand that Autodesk is an American company and .ies is the most common format there, but a good chunk of my work here in the UK uses Eurpoean fixtures and there is a large number of .ldt files floating around.
I have got a conversion programme, I personally use OxyTech's Lightstar 4d, but really it's very irritating to have to manually convert dozens of different .ldt files so I can use them in 3ds Max.
Is there a plug-in/script/something so I can import .ldt easier?
I tried to create a rendering utilizing the IES file from a light fixture manufacturer and I can't seem to get the photometric web to distribute along the full length of the bulb. It looks like the light is being distributed from a point in the middle of the light fixture although it is a 4' T8 fluorescent bulb. In the light family Light Source Definition, I set the Emit from shape to be a line and set the Light Distribution to be Photometric Web and set the Emit From Line Length parameter to be 4'. The distribution of the light looks correct, but just only from a point.

i'm guessing this is some sort of plug-in for photoshop or maybe illustrator? i can't imagine anybody taking the time to do this by hand... at first glance it seems like a bevel effect but i can not duplicate it without going through a long process of filters and adjustments. it seems to be some sort of gel effect...
does anybody recognize this effect?
plugin that would make reflective surface texture out of nothing? I searched in the bar but it seems I can't find one.
something like this but more flat

Description or definition of a "Reflective Ceiling Plan" to give to the guys in the shop? Some of them are having a hard time interpreting the drawing and I guess I am not able to communicate it to them properly.
View 6 Replies View RelatedI have both PSE 10 and LR 5.2, but am not that comfortable with LR yet. I took a new photo and brought it into LR for a few edits, then did "Edit In" to finish the edits in PSE. The file was a Tiff at that point. I went to use the "Touch Up Scratches and Blemishes" tool, and it wouldn't allow me to use it until I got the prompt to convert from 16 bit color to 8 bit, which I did. Then did a bunch of other edits in PSE, and did a "Save As" to a JPG file. On the "Save As" dialog, the only option I had for "Color" was a checkbox that said "ICC Profile: ProPhoto RGB". Left that checked.
After saving the file, I looked at the file properties on the "Details" tab. It shows the "Color representation" as "Uncalibrated" and the "Photometric interpretation" as "RGB". Normally when I don't do the LR edits first, the "Color representation" is "sRGB" and the "Photometric interpretation" is blank.
So the questions: Is what I did OK? The final jpg file appears OK when I took at it in Windows, but wonder if I am going to have a problem somewhere else. Did I lose detail in converting from 16 bit to 8 bit to do the edits in PSE? Should I have done something different along the way, assuming I wanted to do my final edits in PSE?
Is there a good way to either tone down or remove the reflective glare that frequently shows up in a photo subject's eyeglasses? I have a number of otherwise nice photos, but the viewer will always see these glare spots first.
View 7 Replies View RelatedI have a problem with Inventor 11 Studio. The reflection on the ground made by "XZ Reflective Gp" works in a way that when rendered, it shows a partial or cut reflection of my assembly, see attached .jpg file. I have not found yet where this "reflection depth" is regulated.
View 9 Replies View RelatedI am trying to use AutoCAD to render some small parts. I am used to using Inventor Studio, but AutoCad's rendering tools have taken some getting used. to. I have everything figured out, with the exception of the ground plane for shadows and/or reflections.
I originally wanted a ground plane for a shadow to be projected on. However, I had no luck with that, so I modeled a large box under the part. Using that, I am able to get a shadow, or reflection, BUT, the edges of the box are showing in the background. The easy fix is to make the box larger, however, I need the reflective surface and background to be white so that it can be printed on paper without seeing the rendered edges.
How can I set a ground plane, or model a plane, for shadows or reflections, AND made it true white so that the edges cannot be seen?
how to achieve a polished, reflective finish on these machined parts (see attachment)? I've tried all the default materials and even some of my own but can't get the results I want. One factor I can't solve is the location for "advanced" materials in the Create Material pulldown in Materials Browser, this selection is not listed.
