Hi Nick
Thanks for clarifying. These facts make GPU particles very cumbersome to use for environmental effects in many cases for our current project, which is a bit dissapointing.
I see how to go ahead with your proposed “fake” solution, where I would wish a bit more background or a tutorial is on how to solve this using the top-down shadow map approach (Haven’t seen/done this yet).
In general: Is there any better solution on the horizon? Are CPU particles the way to go here?
Cheers,
Michael
