hey!
i’d love to help, but i don’t get how that pressure pass works in dx9 version (texture feed back without framedelay??)
anyways, blending in tfx should be like blending a fullscreen quad in a renderer with clearing disabled
as for iteration count parameter - it supposed to be working in .fx shaders, iirc kinda similar to spreading? (i never actually used it:) )
would be cool to have iteration feature for tfx tho, where it repeats the same effect with output fed to input of the next iteration
btw here is a port of some webgl fluid thingy i played with a while ago (some parameters are messed up, but it worked for me)
