How to color an object in blender for use in Unity3d? I have no knowledge of Modelling but I have to do this for my game. I used texture paint to color the surface. But when I import the exported fbx into unity, none of that paint is there. All I get is the raw model. How can I paint a model for use in unity?
You can apply your texture image in Unity. Put the image in your Unity assets folder, then you can drag and drop the texture straight onto your model, that's how I've always done it anyway

Also, I think you can export the texture with the model if you load the texture onto your material slot in blender, but I always find the first way simpler
