Hasta La Motion!

Hey all,

I have a problem that I have been messing with for a while and haven’t found a fully acceptable solution across the board. There may not be one.

When producing Maya renders I have found it extremely difficult to nail down a good pipeline for motion blur and DOF. I usually prefer to render with Mental Ray. It has better anti-aliasing, filters, outputs and the obvious additions of GI and Final Gather. However, the motion blur and DOF renders are murder on render times! The sampling rates go through the roof if I want a nice smooth render. Maya software seems to handle DOF as a post effect and is beautifully smooth for almost no additional cost to the render. But its maya software. MS motion blur is pretty crappy as well.

I have experimented with motion vector passes and Depth passes to use in compositing and have received mixed results. When using the mr passes system to output motion vectors I get weird results as 3D objects pass in front of one another moving different directions. I have briefly used Toxic and RSMB for AE. Would using something like Nuke handle MV passes better?

Also the Lens blur filter in AE is decent, but pretty slow as well.

What are the processes you all use to achieve DOF and Motion Blur that doesn’t totally swallow up chunks of time and resources?

Thanks all!

Hi all,

I just set up a glass shader which uses a HDRI for lighting the scene a ramp which controls the transparancy and the material itself is a blinn. I render with mental ray, Raytrace, Global Illumination and Final Gathering turned on. It renders fine when I have refractions turned off in the blinn settings. But as I want to render a glass I need refractions. So I turned it on and the glass is almost black…

Hello,

Short version:

Is there a way to call a render and save it to disk of a particular frame from within a MEL script ?

Longer version:

I’m programming a script in Maya for a non CG project – it serves mostly as a UI for another system … Thing is it turns out we’d like to render some frames after all but the thing is our code builds its elements per frame then deletes them all ready for the next (we output text files for use elsewhere), keeping everything and/or keyframing visibility and other attempts have bogged down the RAM with waaaaaaay to much geometry. If we could just call a render from MEL at the end of each frame that would output to disk it’d be awesome. When I select and use the render panel I see no MEL output in the script editor happening from which to distill the commands…

Is it possible ?

Kind regards…

After facing lots of problem finally i created Height and Depth pass shader successfully ..
so here i copy the link of procedure about how to create "Height and depth shader” in maya
