renderman renderers that work with Maya. MR calls its equivalent "Detail Shadow Maps".


not sure why my response is showing up first.

Is it possible?

Houdini has it: http://www.sidefx.com/docs/houdini10.0/rendering/deepshadowmaps



Deep camera maps are useful for rendering beauty images rendered from a camera.

Deep camera maps work similarly to deep shadow maps, but each pixel stores multiple “channels” of information for each surface “hit” by the light ray.

A standard deep shadow map (DSM) stores two channels per “record” (hit surface): The Pz channel stores the z-depth associated with the record, and the Of channel stores the cumulative opacity at that z-depth. A deep camera map, in addition to the Pz and Of channels, stores all [deep raster|deeprasters] planes for each Z-record.

Because a DCM stores color, opacity, and depth, you can use it to render out scenes with transparency (such as volumes (http://www.sidefx.com/docs/houdini10.0/rendering/volumetricrendering)) and then composite the rendered DCMs together with correct depth compositing.



It be nice to have something like that in Maya for fluids and particles

Are u refering to deep shadow maps or deep camera maps because I know Detail Shadow Maps do not do what is described in Deep camera maps. It's more for compositing volumetrics/fx. Thanks.
