I'm bringing Jason's old thread back to life.

IPR: sharing IPR buffers? [sidefx.com]

Anyone have any success with this? I've had mixed results. For example, whenever I use the “ray_deep ipr filename” as a pre-include I get a nice little iprcache file that is about 8MB, (58 channels), but when I do it the normal way Houdini generates one that is about 20MB, (60 channels). And doing i3dinfo on the caches I seem to be missing MColor-Aux and MColor-Aux-Length. Sometimes my hand made caches will render fine, other times they will render with no color but with an alpha. Anyone work out a good workflow?
