Foam specular

[fingerindustries]

Hello,

When rendering foam as a separate pass, how do you extract the specular highlights on each bubble?

Obviously the foam on a black background can be used as a layer above as a Screen mode layer, but this will only really work for white foam.

The foam alpha channel doesn't contain the specular highlight, just the falloff of each bubble.

Any ideas?

Thanks.

yes, the alpha channel contains only the falloff, there is no way to extract the specular highlights, unfortunately they are not added top the specular render element, thanks for the point, we will fix this
