Maya :: Mental Ray Features Tab Interface Shrunk
Oct 17, 2012
I have been doing contour renders with Mental Ray. Suddenly the interface in the Render Settings > Features tab has shrunk into the upper right corner, instead of taking up the entire window space.
Maya gives me the following error message:
Error: file: C:/Program Files/Autodesk/Maya2013/mentalray/scripts/createMentalRayFeaturesTab.mel line 835: Cannot find procedure "miContourEqual".
I have deleted prefs. When that did not work, I uninstalled and reinstalled Maya. That has not worked, either.

I installed 2014 on a Mac Tower (fairly new) and a Macbook Pro (very new) and this same thing has happened to both. After Clean installs and the usual trashing of prefs. I looked at the mel code for the error message I have been getting..
The problem seems to be in the Mental Ray Mel.

I tried starting Maya 2012 from the terminal and it started fine.Then it gave me this when I opened Hypershade libpng warning: Ignoring attempt to set cHRM RGB triangle with zero area...As soon as I made a mental ray node , in Hypershade , Maya crashed.And before crashing it spit this out
Qt has caught an exception thrown from an event handler. Throwing exceptions from an event handler is not supported in Qt. You must reimplement QApplication::notify() and catch all exceptions there.terminate called after throwing an instance of 'M2MI::ApiOutputError'maya encountered a fatal error
2012 Hypershade works fine on windows at my friends place. Do I need to upgrade my QT to the latest build ?
How am I supposed to render my scene with AmbOcc and SSS and all.

Just want to report that the latest release of Maya 2014 Service Pack 4 still crashes instantly when you try to render any polygon instances. Even cubes and spheres. Worked in 2013.

I have installed Maya 2014 SP4 at home, this is a fresh install and was just trying to see if there are any problems with the new SP before I install it at work.
But for some reason, the install went OK, but when I looked under the Render settings there is no MentalRay, and then looking in the Plugins list, there are none there either?

viewport2.0 is not supporting for mental ray shaders. When in enable view port mental ray shaders are showing in pink color.

I am hardly trying to animate a fractal texture applied to mental ray reflection blur value of a blinn material. I keyframed the time value of the fractal: 0 for the first frame and 5 for the 180th frame(the last frame of the animation). If I batch render the scene all the frames look identical. If I render several frames in Maya render view by jumping from frame to another frame I get the same result: no change of texture. But, if I play the animation before rendering a frame in render view they look different that is I have an animated texture. I wonder why the texture does not animate? Amazingly, the fractal preview does animate! I tried to set the maximum value for time, that is 100, I changed the Time Ratio to the square root of the Frequency Ratio with no effect.

I'm thinking about moving to Maya or 3DS Max, and have a question for long-term users. How much does the interface in Maya change with each version? Do long-time users have to spend time searching for the new locations for old controls every time a new version comes out, or has it remained relatively unchanged?

what information regarding countersunk holes is exposed in the Inventor API? Can we extract individual values for the countersink diameter, the countersink angle and the through/straight hole diameter and depth?
While I'm at it, is there an in-depth reference document (PDF) for all of this information. The only thing I could find was an image of the object model but that only gets you so deep and doesn't have an explanation of any of the properties shown on the chart. (I tried searching for various hole-related properties shown on the chart and got zip.)

I have an image that is 15000 x 10000 pixels, 529cm x 374cm. It has been created at 72 pixels/inch.I want to print it out at 100cm x 70cm at 300pixels/ inch.can the larger 72ppi document be 'shrunk' to accomodate for the 300ppi print requirement?

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.

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 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

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 just tested some of my scenes from Max 2011 in 2012, and rendering is in average about 30% slower than in 2011.
I am attaching pictures for reference. It is obvious that they are 100% identical, there is no difference quality wise, but a significant difference performance wise. I will add some more result comparisons on more complex scenes to confirm the problem once they finish rendering. I am willing to provide my scenes to Autodesk if interested to solve this issue ASAP.

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'm currently doing an architectural visualization piece and wondered if there was a 'standard' Haze setting on a MR Daylight Solution for a realistic indoor scene?
The renders are looking quite nice, but was told altering the haze could give it a more realistic appearance.

I what to know who many max users use the DBR feature, because i hear from AD that this is a very rare used feature.
I use it very often for previews and sometimes for final rendering, because it's faster to activate (compared with NetRendering and split scanlines)

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?

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 do not use Mental Ray at all. I am not interested in it. Ideally, I would uninstall all Mental Ray plugins but unfortunately, it seems Mental Ray classes are required by Substance.
I would love to have Preferences->mental ray-> Enable mental ray Extensions switched off by default. Unfortunately, I am unable to get this!
I have a MaxStart.max file with my basic VRay settings, VrayPhysicalCamera, Vray sun and sky system already in place. This is how I would like to start my each and every new Max scene. Unfortunately, regardless my settings, each time I restart Max, these bloody "mental ray extensions" are on again and again.
Is there any method to keep them off efficiently? So this does not return anymore?
