Hi there, I want to know if theres a possibility to make lights invisible in refraction while generating caustics, there are some cases where it could be interesting to create an artifitial light to generete them, here is a material study generated in Vray and Corona, in Vray i can make them invisible for this porpuse. I know we can generate only the channel and include them later, but it would be pretty useful to use it directly from the VFB.
Thanks for all your hardwork.
