Hasta La Motion!

I have also used mayas writeTo buffers together with custom color in the pass system in order to get stuff out of Mia X Passes. So what I am saying is that I am comfortable using either mayas built in buffer system or ctrl buffers, however the question lies with performance.

I’ve read tons of opinions on both using old school buffer systems and mayas newer buffer nodes. I’ve heard about maya getting really slow after using a certain amount of buffers (never reached that threshold) or how the passes system with buffers is broken for mental ray. Like I said..I’ve worked before, but have not made any performance tests as from what Ive seen both are pretty much the same deal. So I’m asking you guys, what is more efficient, less broken, better performance at rendertime? Or should I stick with both..mayas pass/buffer system for maya materials..and ctrl buffers for MR?

Same deal goes with la Maisons motion vector shader…

Any thoughts would be appreciated since I’ve got a collection of shaders which might be getting a little obsolete and want to make the list a little shorter.

Thanking You,

anybody please tell me about the production pipeline in our industry. Means the details for pre production & post production. Or any another steps are there. 3D software case what are the pipe lines (when rigging and texturing will do etc). Because am totally confused. please help me friends.

We are using Maya2010 with Pavel Shaders followed by DeeX shaders. I usually use mostly Mia_X_passes shaders exclusively and then comp in Nuke. I want to use EXR for these layers if possible.

I’ve run many tests and combinations but always seem to be having problems. Like i still can’t get a shadow pass going with the DeeXshaders. I am trying to get these layers generally –

Diffuse Result
Shadow Result
Specular Result
Reflection Result
Refraction Result
Ambient Occlusion Result
2D Motion Vector Result
Indirect Result
Depth of Field Pass

I assume the above is all I need to re-create a beauty pass and have control of the shot right? I am embarrassed to say that I still can’t get these things figured out and I really don’t know what I am doing anymore so please do be specific.

Things such as the Depth of field pass. I seem to be able to get it using the standard render layer passes that comes with Maya2010 but I want to streamline everything and not be so lost. In the render settings does "ticking" the z-depth matter if we are rendering a zdepth in the Deex buffer writer? Which passes must be 32bit and which must be 16bit?

Do you guys use the DeeX shader with p_open_exr or just EXR(mi). Why is it that in nuke I usually don’t get all the layers, sometimes their just blank. What do you do to get the above layers?

Thanks guys. Your lost render passes dude.
And I am aware that Maya2011 is supposed to solve the Shadow pass issue but I dont think we are upgrading anytime soon =(

My scene is a tentacle moving around – as well as a camera moving around it. I am trying to export the motion vector data from maya to do the post compositing motion blur but I can’t find a suitable shader to apply. I tried the lm_2MV shader with no luck, tried the mv2DToxik but am getting very weird results, tried the 3d and normalized 2d as well.

The problem with the 3D blur is that it is giving me more than just Red and Green. The problem with the normalized 2d is that the values are all within .001 of eachother inside Nuke (the image looks completely yellow) and it has a grey background, which I suppose can be matted out with an alpha. The mv2DToxik pass is like a rainbow on crack.

What am I doing wrong? Maybe someone out there has figured out a good way to get motion blur inside of nuke from Maya2010? RSMB doesn’t work well for my scene either.
