I wanted to generate maps using this material: http://puu.sh/fqQt1/21b780e863.jpg It has a nice bump in the preview but when I use it the bump is just plain grey. The material also has no bump in the preview in 3DO or in UE4. Is there any setting to enable bump generation or am I doing something wrong? Thanks.
There's a Rounded_Corners node under Nodes>Bump. Plug that into any material's bump port, and change the Bump mode to one of the "Set Bump Vector"s of your choice. Works like a charm.
