speaking of openGL rop - I am trying to get previews working like this : after setting up a dynamic sim that needs to run for a good while, chain link an openGl rop, si per each simmed frame, you get a preview frame, (ala flipbook). Works for particles, geo, and volumes BUT - when setting up a simple fireball sim, it captures a grayscale version of the volume, even if the viewport is more colorful...
Looked through all the options, but non unlocked the flipbook look...
So what I am trying to do is flipbook (exact vieport capture), while the cache is being created, one frame at a time - and since the output would be a dropbox shared folder - I would be able to monitor status at my conveniance....
There was a mention that for high transparency MATERIAL SHADERS should be used - but I don't udnerstand what that is reffering to...I just dropeed an off the shelf explosion that has a fireball shader already on...anyone dabbled into this ?...
