3ds Max: Shadow Casting on DustDevil plugin

Hello everybody !


It seems that DustDevil (Blur Studio free plugin) is the perfect plugin to make high density cloud with not much time rendering...


I only have one problem : i don't understand how shadows

behave in this plugin! I made a lot of tries (really) and i can't

change the color of the part of the cloud witch is non illuminated... nor see the effect of self shadow casting...


Although i put 2 lights in top of it (one with map shadow and the other with raytracing) there is still no effect !


If someone have an answer on the use of this great free plugin, it would be great...


Note that DustDevil seems to be the new version of FireStorm plugin.


Thanks!
