SSFX Posted June 11, 2015 Share Posted June 11, 2015 I'm usually render foam and spray as "uniform volume" (from the material gallery, apply it to your foam points). Some people will say that this technique lacks the specular aspect of the foam, but I tend to think that this gives me the best results overall. You can play with the intensity and shadow multiplier until you get rid of the dark shadows which makes foam looks really fake. Foam is an scattering heavy material almost opposite to the look of solid points. Hope this will help. Alex Quote Link to comment Share on other sites More sharing options...

rolfcoppter Posted June 18, 2015 Share Posted June 18, 2015 When you render with the Uniform Volume shader make sure that you have converted your whitewater to a VDB. It should already by Default but if you changed your file to only render the points maybe your skipping that step? Also in your render settings you may need to increase your Transparent Samples to get a better look when rendering volumes. Quote Link to comment Share on other sites More sharing options...
SSFX Posted June 18, 2015 Share Posted June 18, 2015 I would disagree with the vdb conversion. Depending on the type of simulation, foam layer will often count more points than the main sim. Converting millions of points to vdb can take a while to process and will take disk space. You can simply replicate more points between you simulated points to get a similar result way faster. I always felt like the vdb conversion was a mistake in the default workflow provided by side fx, but I might be wrong. Quote Link to comment Share on other sites More sharing options...
