I manage to make some kind of drawing tool for unity in runtime. This tool have to work like this: Ingame video of Street Legal Racing Redline. This tool is not just projecting, but edit textures itself.
Just to clean understanding: yes, i know how projectors works. i personally made something like frameshift decal framework, but for complex objects.
1)How do u think it may be done? Easiest way is combine projected texture and original texture of object (as i think, of course if build-in projectors don't build culling mesh).
2) Is it possible to save result of projection? Any ideas are welcome :)
Best regards, DEtH_MoroZ.
I'd be slack: I would assume that UV mapping is sufficiently proportional to just find the UV of the center of the brush and paint around that in the texture. The only tweak that would be essential is ensuring the painting is clipped to the UV mesh island is started on - probably need an extra control bitmap for that.
You could extend this by casting multiple points and deforming the brush accordingly.
