Decals in UE4

Today we looked at creating a scratches decal in Photoshop and importing it over to UE4. The first step was using the brush tool in Photoshop to simply create some lines, that when used with a transparent background would resemble scratches on any underlying textures. Then, importing these into Unreal Engine, and changing the material properties to 'deferred decal' allows us to paint the decal all over the level.

The next thing we looked at was creating unique shapes using practical methods and translating those into the digital world. We used ink and sponges and created a number of interesting shapes using this method, then using the selection and fill tools in Photoshop, I created a slime looking decal for use all over the level.
