Maya :: Why Does Mental Ray Node Causes Crash
Jun 18, 2011
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?

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 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 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 am working in the Hypershade in Maya 2009. I need to see my place 2d texture nodes for my file textures.
Somehow they seem to have disappeared completely. There are no nodes in the utilities tab, and expanding the network to see inputs and outputs is not showing them either.

If there is a way to change the behavior of the middle mouse button in the Node Editor so that by default it moves the panel without needing to press the Alt key?
Ideally I'd like to swap the behavior of pressing the Alt Key + Middle Mouse with just the Middle Mouse.

We recently upgraded from 2008 to 2012. Sometimes, on saving a scene file, some of the meshes within a group node "disappear". They basically behave like they're on a hidden layer -- even though they're not. You can see the transform and shape nodes in the Outliner, but in the viewport they're gone.
I can fix this by un-parenting the missing meshes, at which point they reappear -- and then when I reparent them as children of the original group node they're fine. But when I save the file and reopen it, the meshes are (sometimes) invisible again.
You might think the group node itself is hidden or attached to a non-visible Display layer, but it isn't. And there are other meshes within the group node that show up fine.
How I can permanently avoid it? I'm working on fairly complex environment scenes, and having to selectively unparent/reparent meshes each time I open my files is a real hassle.

I’ve got a small issue when migrating an in-house Viewport Renderer plug-in from 2012 to 2013, when resetting a scene (for instance by creating a new scene or opening another one).
In 2012 version, when creating a new scene, a node removal callback was triggered on every node of the scene to clean things up. More precisely, by installing a callback this way: _callbackRemoveNodes = MDagMessage::addParentRemovedCallback( removeNodeCB, (void*)this );
the method removeNodeCB was called on each Dag path of my scene. Which was pretty interesting for me to clean a dual scene graph within my plug-in
In 2013 version however, none of these nodes removal callbacks are triggered on a scene reset (they are correctly triggered when manually removing a node of course).
Is there a new way to deal with scene resets in the API that I didn’t see or is this simply a bug I should report?This is a cross-post from the SDK forum. Since my issue is strongly bound to the 2013 version.

Suppose I have an asset containing three transforms:
-transform A with published attributes tx, ty and tz,
-transform B with published attributes rx, ry and rz, and
-transform C with no published attributes (nurbs sphere used for selection).
Is it possible to make it so that when the user clicks on the nurbs sphere, the actual asset node gets selected instead of the sphere? I seem unable to set it as the selection transform.

How to delete all ik handle nodes in a scene and all constrain nodes in a scene.
My rig is so complex that going in and deleting one by one seems like a crazy process but if there was a way to get the outliner to show only ik_handles and or constrain nodes then I could just select them and delete them and this would save me a lot of time.

I am having a problem with Maya 2013 (Mac) crashing when I delete history. I have had this happen a few times in the past but only if I go a long time without deleting the history. I do it on a more regular basis now but this past week it has been doing it every time. I created a button on my shelf as a short cut for this and when I was first having the problem I found that if I just do it from the edit drop down then it worked fine...at first. Now it is crashing even when I do it from there. One instance I saved before I deleted the history and it crashed when I deleted. Then I restarted my computer and the first time I deleted it worked but next time it crashed. I have both service packs, I'm not sure why it is doing this all of a sudden.

I was working on setup up several camera animations in a file. I saved the file, and put the settings in for all 4 cameras to render. I started Batch Render running, it saved, began rendering the first frame and then Maya crashed. It was able to save a .mb version as it was closing. I have since been unable to get either file to open correctly.
If I try to directly open the files, they load 100%, the status bar immediately switches to "Writing <username>.20110503.<time>.ma" and the Crash Reporter appears before the viewport can even update and show the model.
If I try importing either file into a new document, it will load completely, and a dialog window pops up with: Could not save file"/var/folders/FL/FLo7J2o4H4OV9SDiREDU4U+++TI/-Tmp-/thompirson.20110503.1216.ma".
If you click OK, Maya crashes without the Crash Reporter opening.

An animator has been getting a crash when unloading a reference in some of our scenes. When I take the same scene and try the same unload-reference operation, it works fine for me without crashing.
I've attached the crash log from the animator's machine.
We're both on Maya 2013. I'm on Windows 8, he's on Windows 7, in case it's relevant. We're using the same set of custom plug-ins.
Note that we're not using nested references - this is a top-level reference that we're trying to unload.
I noticed this in the online readme file for Maya 2014: MAYA-19363 Unloading reference node may cause Maya crash.
If so, is there a workaround for Maya 2013 till we all move over to Maya 2014?

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.
Jennifer O'ConnorMastering mental ray ®Rendering Techniques for 3D ... is generally required for all 8-bit images saved as JPEG and PNG, and not ...... I found that most people where confused about PNG being 16- bit. Now I see I am doing good to keep the resolution and pixel size down to 8 bit.

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.
