How to make good puddle with Decals ?
Hello. I have a problem with Decals. Can someone please give me some advice about how to create good looking puddle with decals ?
Right now I set my decal material to Deffered Decal > Masked > Stain.
I set my reflections to pure white, my roughness to pure black and my opacity to "puddle shape" texture. It is looking fine but very boring. I want some variations in depth. I thought that I can easily achieve it with Opacity mask (some grey clouds from PS or something) but "Opacity Mask" is greyed out in every decal material type :(
How I can add some opacity depth to my puddle ?
Thanks and Cheers !

So the best example and information I can provide is actually within an example project we provide via the 'Learn' tab on the launcher. It is called 'Reflections' and has a high quality example of a Water Puddle with motion and faked depth.
I say faked depth, because the depth expressions only work with SM5 shader models. This means you cannot use the Depth Fade expression when working in the Deferred Decal material domain as I initially stated.

An example of one of the puddle decals from the Reflections example project. Let me know if you have further questions or need further assistance.

Take a look at the 'Depth Fade' node to control the depth of your puddles opacity. To use depth fade, you will want to use a translucent decal instead of masked.
Hopefully the documentation can get you on the right track, but if you still need assistance let me know and I can look into this in greater detail with you.
