I wanted to use texture projection for camera as described by In this series. However the explanation of the settings used is not described in his video clearly. Particularly this setting which is found under the Project Paint panel in texture paint mode:
The tooltip says: "Paint most faces pointing towards the view according to this angle. "
My question is: How is this angle affecting the projection? Is it the angle of the camera with the surface of the meshes?
Please do explain in detail what this angle is and how it affects the texture projection. Some illustrations would be helpful. Thanks in advance.
