Farsheed Ashouri Posted August 14, 2009 Share Posted August 14, 2009 Hi Folks, I came from Maya so please excuse me for asking stupid questions. Could you please help me finding a nice, simple sss shader? I know how to code in rsl and vex a little but I believe a working example would help me a lot in understanding the basics of houdini. I really need this help because I've started a project and done many of modeling and dynamics in houdini, now in render, I couldn't find any working sss shader and the project deadline is up. Thanks in advanced. Quote Link to comment Share on other sites More sharing options...

Thanks in advanced. Hi Farsheed, There's a very nice SSS shader in the Material Gallery called Skin. I believe you can tune it to behave how you wish even if you're not rendering Skin. The only requirement is a special point cloud generated with the SSS Scatter SOP. Check the docs as I'm pretty sure it's all covered there. Otherwise Serg has an excellent SSS shader on the Houdini Exchange. Quote Link to comment Share on other sites More sharing options...
Farsheed Ashouri Posted August 15, 2009 Author Share Posted August 15, 2009 Thanks Alan, I'll check that. Quote Link to comment Share on other sites More sharing options...
Farsheed Ashouri Posted August 15, 2009 Author Share Posted August 15, 2009 (edited) I tried to find out the problem but I couldn't. This is my scene file that I want to add SSS to it. Could you please modify for me. contains a sphere and a light. Thanks you in advanced. sss_test_odforce_v01.hipnc Edited August 15, 2009 by Farsheed Ashouri Quote Link to comment Share on other sites More sharing options...

Both the SSS Skin and Wax shaders require you to generate a pointcloud. The SSS Scatter SOP I added to your geometry network is used for this purpose. Also notice I reference the pointcloud inside the shader so make sure it knows where to find it. sss.tar.gz Quote Link to comment Share on other sites More sharing options...
Farsheed Ashouri Posted August 16, 2009 Author Share Posted August 16, 2009 thanks man, i got it. Quote Link to comment Share on other sites More sharing options...
Farsheed Ashouri Posted August 18, 2009 Author Share Posted August 18, 2009 Ok, After some tests, now I come up with this question: We did the point cloud calculation in sop level, what if I want it in rop level? Because I want to add some displacements and we can't catch them in sops. Really thanks. Quote Link to comment Share on other sites More sharing options...

Displacements aren't really supported with this type of SSS according to the docs. http://www.sidefx.com/docs/houdini10.0/gallery/shop/material/skinSSS Check out the Houdini Exchange for AXIS SSS V2.
