Maya :: 2013 Proxy Render Passes?

Aug 10, 2012

I'm trying to render some passes in Maya 2013 and Mental Ray using proxy assemblies. The trouble is that none of the passes that do some kind of material definition override ie AO, camera depth work correctly with proxies. I have read a few posts where people have said that these passes need to be applied in the render globals when exporting the proxy file. This method works correctly in Maya 2009 and fixes the issues, unfortuently this method does not work in Maya 2013.

3ds Max :: 2011 Render Elements Fails With Bad Passes?

Apr 25, 2011

I am attempting to move a project from Max9 to Max2011. Using Mental Ray.

Test renders of Diffuse, reflection,refraction, shadow, Self Illumination are failing.

The diffuse pass is very dark and looks like it still contains all the elements. But very dark.

The rest of the passes are just black.

I had this render working well in Max9. Perhaps something in the newer version of Mental Ray that I am missing?

I did some tests with just a simple scene. A plane, a box and a sphere. (1.48GB)

Render elements seem to work rather well if the scene is created in MAX2011. So it must be something in the Max9 files that is causing the error. ?

Maya :: Color Management With OpenEXR - Masterlayer Passes Washed Out

Sep 27, 2011

I have recently discovered what I think could possibly be a bug when using the OpenEXR format with Mental Ray passes and color management in Maya 2011 & 2012.

For example If I create a scene using the below steps:

1. Enable Color Management (default linear work-flow)

1. Create a sphere and assign a Maya material or a mia_material_x_passes shader to it (textured)

2. Add the sphere and light to the masterLayer or any custom layer.

4. Create a beauty pass, and associate with layer

3. Change the output image format to OpenEXR

4. Render and the color looks correct once a gamma correction of 2.2 is applied. See image attached goodColorSpace.jpg

However, If I add a (CGpost) pass to the same layer; for example a cameraDepth or Object Normal. The color space for the beauty and even the masterlayer passes are all washed out. See image attached badColorSpace.jpg

It seems that when using Color Management and combining (illumination) and (CGpost) Pass Groups in a single layer with OpenEXR is creating this outcome.

I should add that changing the frame buffer dose not work either, same result with 8bit Int --> 32bit Float.

I have attached 2 images which show that by simply combining a CPost (cameraDepth) pass with an Illumination (beauty) pass creates a very different looking color space.

Maya :: 2013 Render Window Suddenly Fails To Appear

Apr 10, 2013

Last week everything was working fine, this week my render window in vacation. Or something.Hit Render frame or even IPR (doesn't matter what renderer I use) and no render window pops up to chew on the image. I get a progress bar and the .IFF is saved in my project folder, but no render window. No error messages that I can see either, maybe I'm not looking in the right place.

VideoStudio :: Smart Proxy Deletes Proxy File On Sleep

Jan 21, 2013

Mediastudio 5 pro ultimate
Win7 64
AMD 960T on six cores
Asus M5A78L M LX +
8 GB
HD 3000 integrated graphics
OS is installed on a 128 MB SSD
Project target file is on a 500GB WD Blue.

I have ripped a Blue Ray DVD as an .m2t, at an average bit rate of about 18.5 Mb/sec, with a resulting file size of over 16GB. Needles to say this file bogs the machine when not running the proxy. When I finish a session and close the program, the proxy file is gone the next time I open the project. The same thing happens when the machine goes to sleep with the project open. I have to either slog through working directly on the project without the proxy while it slowly rebuilds, or wait a couple of hours for the rebuild to complete.

Any way to stop the file from being deleted? I went to power options and selected never, but the next day it was gone again.

Another thing would be to increase the speed of the proxy creation, as it only uses about 20% of the CPU. Better to get it done faster... I have tried raising the priority of the process to high with little if any change.
