I just tested Flow, and I can only say… AMAZING!
BUT, I have a question, I’ve seen that it can cast shadows on itself (from directional light). My question is: Can it cast shadows from itself onto other geometry? (surrounding map). And can it cast shadows from other light types like spot lights and point lights? Can the simulation be frozen and baked to like a single frame (like : https://i.gyazo/f4b9b68e5b2984f3a3c04b05b60d09ac.mp4 (but so it can be used without simulating or playing the level))?
can you answer those questions? :)
Heres a showcase how the Smoke example looks like:

Smoke interacting with collider (I didn’t get the actual skeletal mesh to work, so I just attached a cube onto him to act as a collider):

Oh also, when I have 2 Flow emmiters like shown in the last example, the bounding box seems to be smaller (?), you can see it aswell in the last example when I move the sphere up, the smoke from both emmiters just kinda stops at the top for a while and then it continues to grow again. Any fix for that?
It actually happens on 1 Flow emmiter aswell I guess (see the first link of the smoke from geometry example, it kinda stops at the top, and I’m sure that the grid is much bigger than the actual simulation.)
