anicg Posted August 23, 2022 Share Posted August 23, 2022 (edited) I have attached files. I just can't get any self-shadows on volume. I've rendered the shadow matte testing on a polygonal geometry and it works like a charm, but for the volume (in this case a cloud) I can't get anything at all, using both: - just shadow matte AOV - duplicated volume with shadow matte material Everything works fine for polygons, nothing whatsoever works for volumes when it comes to shadow matte / pass. Am I doing something wrong? I need the self shadows of the volume. The volume (cloud) is from Disney: https://www.disneyanimation.com/data-sets/?drawer=/resources/clouds/ And here are the houdini hip files shadow_matte_polygonal_geometry_works.hiplcshadow_matte_polygonal_geometry_works.hiplc floating.bgeo.sc shadow_matte_volume_does_not_work.hiplc shadow_matte_polygonal_geometry_works.hiplc Edited August 24, 2022 by anicg Quote Link to comment Share on other sites More sharing options...
