ykcosmo Posted December 11, 2005 Share Posted December 11, 2005 I used slim to make a raytrace shader (occlusion) and assigned to each object( a simple sphere and a ground plan), when I render, it said: Shaders invoke raytracing, but no traceable objects exsist. I generated the rib file, and there is no trace option in the rib file! there is a raytrace parameter can be checked in rat.where it is in houdini?maybe ....should I insert raytrace option in rib file? thx for help!

George Posted December 12, 2005 Share Posted December 12, 2005 Hi ykcosmo, It depends on which version of Houdini you are using. In 8.0, the raytrace visibility options are in the Geometry Object's parameters under the Shading | RIB folders. There are various attributes for the different visibilities that an object can have for particular rays. Hope that helps, George. Quote Link to comment Share on other sites More sharing options...
