Hi

I want to use this with a transparent background:

Any idea on how to change the provided shader etc?

Many thanks

change to what etc ?

There's a cool demo linked from https://github.com/codrops/RainEffect,​​
By transparent, do you figure it would be enough to sample a texture containing a recent frame, or perhaps an environment map?

(Also mods this editing box is absolutely horrible sometimes - I wish it was less quirky to post responses here, I reckon it cripples the general forum interaction)

Yes in the demo they use a foreground and a background texture. Now for me it must be a transparent background texture. If you try the demo with a transparent background it looks terrible.

What will be rendered behind the transparent background - what do you suppose you'd want to refract?

It's a game engine in the background, that I cannot control. I would want to avoid dull color maybe with a shader correction to make drops more look like water. Without background I have it mostly looking like the demo in old Internet Explorer, terrible.

ok it is better for u then, to learn how to code a rain shader and then u can change it as much as u like;

so follow this:

it's got 6 parts or so… the dude on the video said he doesn't know Maths -lol- so it's not scary ?

u'll be proud of yourself when u've gone through it all ?

as u follow the tute, u can edit your shader on shadertoy.com if u don't have anywhere else to try it on…

That's it … all the best ?

Thanks didn't know that site. If someone could compile the demo shader with shadertoy it would save me time, else I will take the plunge and learn shader from scratch.

no luck with shadertoy but with nsight.

Any ideas on how to deal with gameengine background?
