Did you do the same and get something different? I noticed when I changed the lighting the model actually disappears, and looks like that when I save and reopen it. Kimera doesn't like this models texture. I actually built and altered the model without it, just as plain white pieces. Otherwise Kimera would crash.
I thought the new colors looked pretty good in the game. Other than recoloring it I didn't change anything else like the lighting so it's the same as Kelas original.
