Question: Having limited experience with particle and mental ray since I mostly deal with renderman and houdini. My question is in regards to sprite rendering in mental ray. My sprites in hardware render work perfectly however when using mental ray I notice a large difference most with opacityPP attributes and lifespanPP just plian crappy. There not working any suggestions ?
I am guessing that particleSampler would be needed but not sure how to incorparate that into a the spriteTEX shader.
Here a list of support that Autodesk claims that work !
positionPP, spriteScaleX, spriteScaleXPP, spriteScaleY, spriteScaleYPP, spriteTwist, spriteTwistPP
spriteNumPP is unsupported ( great who needs that right guys )
I am sure there other things not supported that I am not aware of. For those who know please list your experiences.
