My pack of 200+ grunge decals is now up on the Unreal Marketplace! (https://www.unrealengine.com/content/2a62cea451cd4bcea18aa69695b2d287).
***NOTE: Currently it seems like you can only create a new project with this pack, so if you want the decals in your own project you’ll have to create a new project and then migrate all the files over to your own project. Also the experimental DBuffer setting is currently enabled in the master material, so if you migrate the files over to your own project and you don’t have the DBuffer decals settings enabled, the decals won’t show up. I’ve contacted Epic to get this changed, but in the meantime to fix this all you have to do is open the master material and change the “Decal Blend Mode” property to “Translucent”:
The pack consists of 213 masked decals of dirty concrete/plaster, rust, stains, leaks, etc.
Each has a material instance with parameters to change the color, roughness, transparency, normals intensity, etc.
Base Color and Normal map resolutions:
1 @ 512 x 512
3 @ 1024 x 512
27 @ 1024 x 1024
1 @ 2048 x 256
14 @ 2048 x 512
72 @ 2048 x 1024
95 @ 2048 x 2048
