Im working on a 2-d isometric game where i'm budgeted a 32 frame walkcycle for a mecha robot. I want dust do blow up when it is putting down each foot but unsure how too go about it.
Should I create som sort of plane under the foot that starts emitting when the foot is coming down and make the footpad collide with the fluid or is there better ways? The biggest problem I have with these short simulations (explosions primarily) is that i can't seem to make the animations play out nicely by themselves, instead I have to key transparancy or opacity input to 0 on the last frame but i don't think it looks very realistic.
I don't expect a long tutorial in response, but a point in the right direction whould make my day. experimenting with fluids take forever!=)
