Raindrop shader. Three layers, two dynamic, one static. Packed tiling textures with normals and opacity mask. More detailed breakdown on the way, look for replies to this thread! #UE4 #gamedev #indiedev
Streaks on top, a tiling tex, distortion is animated so you can see the influence of the distortion tex on the left. Drops on the bottom, I use a very small but uncompressed tex that holds different UV values per pixel, this is used to distribute another tex around. #UE4 #gamedev
If you're fine with some quality loss you can strip out the blue channel of the normal and pack in another grayscale texture instead. Make sure compression is default and multiply the normal by 2 and subtract 1 to move it back to the right range. #UE4 #gamedev
A lot of you have been asking so here's more info on impacts. Many ways of going about it but this is what I went with. I simplified this for clarity, I'm also distorting these textures to get a more natural result, nodes in the reply. #ue4 #screenshotsaturday #gamedev #indiedev
Nodes for the result above. #ue4 #screenshotsaturday #gamedev #indiedev
