There would have to be a darker shader set to view the full effect though
This is the issue right here. I won't comment on the neon body parts, since those would be a massive coding job that in know nothing about, but in the case of glowing textures:
Glowing textures wouldn't be that hard. I believe toribash could easily be coded to use emission maps for a glowing effect. I'm pretty sure however that this would have absolutely no effect on things around it, and would only be properly visible in a dark shader, if even then. I for one very rarely use anything but the default shader.
And toribash has enough problems with all the textures it has to deal with. having another entire set just for glow mapping would be a massive load on the servers and just cause problems.
ultimately, I support this, but it's never going to happen and probably never should.
