Thanks! I'm glad to help you!

FuJiy, Thanks! I've done similar experiments with cubemaps, but I haven't tried $envmap so I will try it. I should be able to try to glow too as I have Vegas 16. Thanks for the advice!

And your english is absolutely fine!

P. S. Sorry for my English

Bowmaker Fox, it's easy. Reflective surface was made by "$envmap" and other env parameters. Just add env parameters to personality sphere's VMT file. Also, map must have bulided cubemaps. I recommend original Portal 2 (and co-op) maps.
About glow (shine). In SFM I used a little bit of bloom in camera settings. The glow from core's eye and BM batteries was made by After Effect. Just add adjustment layer with curves or Lumetri color (from fx library) and correct the color. Picture will be looking like yellow tone or red tone or whatever color you like. Next add eclipse mask and animate position if it video. I think, this also possible in Premiere Pro or Sony Vegas and other programs.

How did you make such a shiny, reflective surface on the core? Looks great
