elephantintheway Posted June 27, 2017 Share Posted June 27, 2017 Hey, I'm trying to render some paper/vegetable models so I'm using SSS in the H16 Principled Shader. However, I'm getting a lot of noise. The old Principled Shader on H15.5 had fake SSS, and the Classic Shader only has a Quality slider when using the deprecated physical SSS model, instead of the new BSSRDF. The Houdini docs are out of date and still say that SSS is a fast approx. so is there any other way to increase SSS samples within the shader?

rich_lord Posted June 27, 2017 Share Posted June 27, 2017 I dont know how to do it per shader, but there is global SSS samples on the mantra node. Quote Link to comment Share on other sites More sharing options...
goldleaf Posted June 28, 2017 Share Posted June 28, 2017 You can add the SSS Samples Property to geometry objects: Now when you render, you'll get more samples on the objects where you need it. Pixel Samples are the one property that can only live at the object level; there are probably others, but that's the only one I can remember. Here's some documentation: http://www.sidefx.com/docs/houdini/props/_index per_obj_sss.hipnc 3 Quote Link to comment Share on other sites More sharing options...
