SunsetOverdrive TrimSheet Test

Insomniac games did a GDC talk a while back and I wanted to quickly test some of their techniques.

Just looking for a second pair of eyes to see if the normals are showing correctly.

Well your edges are not at 45 degrees. They kinda dip down and then they flatten again at the border.

The normal map in your test is not hiding the hard edge like in the Insomniac version but your normal map looks pretty similar. Maybe the values aren't quite right in your normal map. Or maybe the edges in the normal map are too wide.

So I had another attempt.. this time instead of doing it manually in Substance Designer I used Ultimate Trim generator instead as it was quicker and easier to work with.

Didn't bother with edge damages either and was extra careful making sure the corners of the bevel lined up with the UV corners. 

looking better?

Again, your edges are not at 45 degrees. You should use the height to normal world units filter in substance or render some normals in something like max to get those 45 degree angles. You can also adjust the strength of your normal inside unreal but that takes some trial and error.

The Trim sheet generator says the Normals are explicitly 45 degress so are you referring to the models normals? Is this where the problem is?
