Thank you very much for the reply. i have heard of Real flow and found it was quite expensive and probably overkill for what i need. you see, i don't really need any special effects, meaning no waves or ripples or such, i merely need to show a hollow box fill up with material, fluid etc. What i am trying to do is simulate a plastic injection mold being filled with plastic. in the past i merely utilized transparency, going from 100% to 0%, sort of dissolving the part into the scene. but this isn't really accurate, especially up close. Rather, i need to show this process in better detail with the material starting at one side of the cavity, or void, and filling to the other side.
thanks again.
Paul
