When I tried to import a .wings file into Blender (using .obj format) and send it to Unity, the color disappeared! Is there a way to keep the color?
You need to understand why there is color in the first place, and where it went.
If you colored it using vertex colors (setting a color in the program, like blender, or wings sometimes does this) you need a shader in unity that then picks this up. Otherwise you could just color it by setting a diffuse material on it, then apply a color via the color settings.
If your asking where your texture went tho, that needs to be imported also, then assigned in the engine.
I’m talking that when I imported the file to Blender, the color disappeared in Blender. Also, I used vertex color.
