Obviously, this was screenshotted outside of the game player while in edit mode, so maybe it's possible to bake this texture to an actual texture which I can apply to a material? This is very likely impossible though, so maybe theres a script someone made to generate the texture for each face? (so for each face just a simple light grey texture with dark grey outlines?)
I have arrived at an imperfect approximation. It will create the effect, but has some flaws:
- Edge lines will be inconsistently thick.
- Center point may not be exactly centered.
However, the result is definitely passable:
To create this, you need a few steps:
UV unwrap it. You U>UV unwrap
Reset the UV's U>Reset
Add an image texture, I used this image:
- Set the UV map
TADA! You have your result!
See the .blend for any confusing details:
