art3mis Posted November 24, 2019 Share Posted November 24, 2019 (edited) Anyone expereinced with lighting and rendering volumes able to offer some pointers? Have a single area light overhead lighting a smoke volume with a simple RSVolume material. Not getting any definition in my smoke. Compare my SceneView on the right below to the render on the left. Is the problem with my lighting or the material or my actual volume? The smoke volume is a narrow box defined by the Smoke object size> .04 wide X 1.5 high by 4 units long. Just trying to get the same detail I see in Scene View. Edited November 25, 2019 by art3mis Quote Link to comment Share on other sites More sharing options...
Howitzer99 Posted December 4, 2019 Share Posted December 4, 2019 For volumes, usually you need to adjust the RS_Volume shader settings to work with the incoming volume. There are obviously a lot that can vary between volume setups, but to get started, the main ones would be the Scatter Coefficient and the Absorption Coefficient. With Big Hammer being the Shadow Density Scale in the Advanced tab. It looks like you're already getting some shading in your render, so hopefully tweaking these parameters will help. If you want to send along a hip file and a single-frame cache (vdb) I could look further. Quote Link to comment Share on other sites More sharing options...
flcc Posted December 5, 2019 Share Posted December 5, 2019 It's look like you have emission active in rsVolume Shader but Volume contribution scale to 0 on the rsLight. Quote Link to comment Share on other sites More sharing options...
