I want to have outlines around things, like green outlines around the edges of teamates, red around enemies etc. in the game engine, I don’t however, know how to do this, does anyone else know how to go about it?
Well, an easy “fake outline” works by:
- Duplicating the object’s mesh
- Scaling the duplicated mesh up a little bit, so that it’s bigger than the original
- Flip the duplicated mesh’s normals (editmode, select all, w, flip normals).
- Set the duplicated mesh’s color to something (like red) and make it shadeless (in materials, or just make sure “light” isn’t checked in TexFace settings).
You get results like in the attached image (though this one also has a shadow).
That would produce lag though on high-poly models, any other ways?
You can make the outline low poly.
If you use glsl, you can make a node shader, and plug the mesh normals into a ramp shader, which when set to the right settings and combined with the diffuse color, makes an outline- something like the attachment. It’s a bit hacky, and only works on smoothed meshes, but it usually gets the job done.

How would I make those outlines thicker?
adjust the color ramp so there’s more black.
Thanks for your help
Thanks for that guys
Thanks Captain, I didn’t even think of that. You may have also presented a solution to a totally different question I had. You’re awesome.
