Anatol Posted November 3, 2011 Share Posted November 3, 2011 Hi! I'm trying to make a volume fog inside a geometry using geo2i3d technique described in cmiVFX tutorial. I "filled" polygonal geometry using isooffset. Mantra render this volume well. Next step inside Ropnet I created geometry1 > conected to it geo2i3d1 and rendered volume to i3d file. Output file size is about 38Mb Next step I load i3d file into texture3d and make next nodes connections: (inside vopcvex1) parameter(point)>texture3d>parameter(density). At this step in tutorial appears volume that can be rendered this mantra, at least that shown in a viewport but I see nothing in a viewport and mantra renders a black square ((( Some people say that this geo2i3d not working well. How can I write volume data that can be read in texture 3d in another way? Thank you. Quote Link to comment Share on other sites More sharing options...

Anatol Posted November 8, 2011 Author Share Posted November 8, 2011 (edited) Hi! Once again ) I've rendered a sequence of bgeo and i3d files and trying to insert them into texture3d. When I'm using just 1 file in a texture3d node ($HIP/i3d/cloudGradient_ani_005.i3d)everything works well, but if I'm trying to use sequence ($HIP/i3d/cloudGradient_ani_$F3.i3d) - houdini is showing just 1st frame of a sequence. I've tried to search some info about Texture 3D in houdini's help but haven't found anything about sequences. Is it possible to use sequence of i3d files with texture3d or gradient3d nodes? Thank you. Edited November 9, 2011 by Anatol Quote Link to comment Share on other sites More sharing options...
