Hi fellow Gamedevs!
I need to bring up a decal lighting issue that has been brought to my attention. By default the deferred decal renderer will not render correctly in the shadows. Here is the work around if this is a problem for you.
Basically for 4.6 engine and before you open the project up.
- Open DefaultEngine.ini
- Goto section “[/Script/Engine.RendererSettings]”
- have the following 3 settings:
r.EarlyZPassMovable=1
r.EarlyZPass=2
r.DBuffer=1
- Start up the project/editor and you will compile all your shaders
- Finally, the last change is to open the decal material and change the “Decal Blend Mode” to “Db Buffer translucent color” or one of the other ones if you need roughness, normal channels.
Have fun with your Gamedev!
