Uninitialized Image TreeDoubleBranchTexture from object "Tree" So I made a UV Texture for my tree and called it TreeDoubleBranchTexture. I decided to change it a bit so the texture wouldn't have any shadows anymore.

I did it the same as I always did but it just keeps saying Uninitialized Image TreeDoubleBranchTexture from object "Tree" every time I try to bake it.

As a way to remove the shadows I made the surface Emission and set the strength to 1.000 for both the wood color and leaf color.
I was having this problem too. It seems I had not actually created an image, just a slot for one. I managed to fumble around until I found Fill Image With UV Grid. Then I had an actual image, which I saved, and then it worked.
