3ds Max :: Rendering Volume Light With Mental Ray
Jun 16, 2011
I'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?

we'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.

I'm trying to render a sequence consisting of some letters with a self-illumintating glossy plastic material.
The object consists of two objects, one with high gloss plastic with a slight transparency, another one within it, slightly inset, with a high value self-illuminating material.
I look-developed it using still mode rendering, but when I started to render as a sequence I noticed it looked different than expected. The difference is in the indirect diffuse pass, which is very noisy in the animated sequence. It also has some very pronounced highlights which are incorrect.

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 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'm using mental ray rendering photometric lights with a lot of reflective surfaces. I keep getting little white specks showing up on certain surfaces.

I have a little problem during rendering interior of apartment. I am using Auto Cad 2009 and I have trouble with shadow and light. In realistic view, when I turn on the sunlight, inside of apartment iz visible only the part of the room on which the sunlight is falling through the windows, and I can't make the rest of the room visible as it should be during the day. Here are the pictures. First is without shadow and light, second is with shadow and light, and on the third is additionally turned on background sky.

I'm working with TIN surfaces, doing cut/fill comparisons for a surface mine.
My volume surface statistics show a cut volume of 5167.22 cy and fill volume of 8456.18 cy.
The sample line group volume report show cumulative cut of 5527.67 cy and fill of 8465.56 cy.
What could be some causes of this disparity. All reference surfaces are built from points and use a non-destructive boundary.

I've read a few threads on this way back but cannot locate them. I have two surfaces and create a volume surface and it reported the volume as 493 cy. I then ran some sample lines at 25 foot interval and the total volume is reported as 964 cy.

I want to use it as my primary hydrologic and hydraulic modeler. It only makes sense. Well, I got the program to work and had things linked in and was able to route a storm through the network. But when I routed the storms, I had to model double the storage that i expected.
So I went back to the program I'm familiar with - Pondpack by Benltey - and designed the same system I routed in SSA in that program - and got the storage volume that I would expect for a site of this size - about 2 acres.
Is there possibly a setting that I'm missing that makes my outlet structures route slower or less than they should? Or is there some other reason that a system would give this kind of inflated need for storage?

I have an issue with using Bounded Volume or Adding a Boundary to Volume Surface things so bad... = incorrect volumes.. sometimes extremely incorrect.. I understand that the surface rectangle when a boundary is added but this could be horrible if not checked.

I'm no longer able to control the PP (monitor) volume using my computer volume controls. I've always controlled the monitor volume using my computer volume levels, but starting today, that has changed.
The volume is just playing at the level recorded with no way for me to turn down or up.I performed a disc repair and that didn't solve the problem.

I am trying to animate a casino-like light board made of tens of light bulbs/leds. I thought the easiest way to do it would be creating a matrix of bulbs arranged by material ID and then design a pattern in multi sub-object materiel so I could somehow scrub through it and achieve animation effect. The material modifier allows to change ID for the whole object only and MaterialByElement shuffle ID`s in a random manner.

I am attempting to build a facsimilie enigma machine, I would like to know how best to create an effect so that when a key is pressed a corresponding letter appears to light up. Btw I am not looking for an animated image, I can take care of the transitions between on and off, I just need to create the two image states.

How do you lock the pivot point of a light to the light itself? I thought just adding a Axis node would move the light and pivot point but the pivot does not move. Is there a way of parenting them together?

How do I use the standard Revit can lights in a wood joist floor with drywall applied to the bottom? If I place in a suspended ceiling, can lights light up just fine. However, if I use them in the floor space of a wood joist floor, the light itself gets covered with the floor. How can I get the light to cut the floor out so I can see the light when it is rendered?

Mostly work in VRay...can't figure out how to simulate the shadows from sunlight, where a window ledge casts a sharp shadow and a distant building casts a soft shadow.

I'm using the metallic preset under the arch and design for mental ray and i've added a scratch bump map. It shows perfectly on the material editor but doesn't show up at all on the actual rendered image.
I've attached the image to show you.

I have made several renders in the Scanline renderer, I've tried to capture as much detail as I can squeak out of it, setting it to the Catmull-Rom filter, Light Tracer, Max Star 2.5, and the like. It creates nice renders for game assets. However, if I switch it to Mental Ray, it seems that a lot of the details get washed out. Are there any 'base setting' to capture every nook and cranny better?

Mental Ray keeps crashing out of memory during rendering. I guessing it's my jpeg images, becuase that's the only thing I am doing wrong. I didn't know what the set standard size it should be. I am using 2048x2048. I am not sure what the set standard is.
Updated my POST due to no replies.

How is it possible for Mental Ray to give me an out of memory error on a Windows 7 professional 64-bit machine using the 64-bit Max Design? I have 4GB of physical memory, but whenever a program needs more memory Windows allocates virtual memory to it, so theoretically my memory limit should be my hard drive space. However, when I try to render my scene with a little less than 200k polys with a displacement map on it (trying to get grass), the task manager shows 3dsmax.exe using up to 4.3GB of commit memory (4gb working memory), then it crashes.
I've set Windows to use up to 16gb for my pagefile, so it seems like mental ray isn't actually 64-bit since it crashes right at the 4gb limit of a 32-bit program.

I am searching for the "mental ray message window" in the 2012 version. ok i've got the German version, but there is only a "rendermeldungsfenster"(render message window) where only the errors are shown. is there any other possibility to see how many final gather points are in the scene?
greetings, mredl
