vbk!!! Posted May 16, 2011 Share Posted May 16, 2011 Hello, I am unable to render a scene using vexvolume procedural. I am using the methode discribe in the fractal tutorials provide by cmivfx. When I use only Volvop (even link to a cvex shader) everything is ok. But mantra render nothing if I try to use vexvolume procedural. If I add some smoke material it render a little square ... Thanks for you help ++ Vincent vm_geo_vexvolume_problem.hipnc Quote Link to comment Share on other sites More sharing options...
andreu.lucio Posted May 16, 2011 Share Posted May 16, 2011 Have you correctly set the bounding box parameter in the volumeProcedural? You will also need a cvexshader exporting a density attribute for this setup to work. Have you done this 2 things? Quote Link to comment Share on other sites More sharing options...
