Hey,
So I found a hand model with UVs and Texture maps online, but the topologie was wrong.
I used the Topobuild to draw over the old model, making a mesh right for animation.
Lastly I baked the texture from the old model to the new model.
Here is where the problem arises. The texture bake shows black lines where the uv border are (See Screenshot).
How can I remove the black lines and why are they there in the first place. I'm still new to texture baking and im having a hard time understanding the whole process.
