Hey guys,

I'm trying to make a classic scene with raindrops in a puddle. As soon as Meteorshower is broken, I had to find a workaraound for that.
What I'm trying to reach is make RT work on Normal channel of the Mod Material. It doesn't work because I can not apply Normals op that requires a Bitmap input, not RT.
I can't find a way to convert RT into normals... Any ideas?
Thank you.

it's a good idea
I thought we could convert RT to a bitmap but don't see how. it should be possible as tex2d can read RT...
Maybe you could use displace for same effect.

Yes, I tried to use the RT on the displace channel, but it just creates craters with rough edges which is not good...

maybe a start of solution

with fix billboard alignment (from screen) and high resolution. it works fine

Yey! This is wicked, mate!
Things to note for me:
1) Normals can be alphaed.
2) No need to use Tex2DAnim for Rendertarget.
Now it's time for the rain and water splashes! Thanks again!

Pretty cool.

not tested, but maybe texture loop is useless, using fadein fadeout in sprites... however it's a good example of animated texture shape

Interesting. Worth a try at least

I tried your approach. It doesn't work for me. It looks like 2 premul alphas (1 for the circle, 1 for sprite transparency) don't work together (they flicker)...
