I am working with Blender v2.78 windows 10 64 bit. I am doing a course using UV projections. When I call Mash => UVunwrap => Cylinder Projection I am supposed to find the Cylinder Projection Panel, but it is not there. need help. Dov
That panel should appear at the bottom of the Tool Shelf, or you can open a floating one by pressing F6. It is only available after you've unwrapped and before doing anything else that affects the mesh.
This is the floating one.
The tool shelf should be at the left side, and if it isn't there, there should be a small plus sign. You can open the tool shelf by grabbing the plus sign with you mouse, and pulling it away from the edge, or by pressing T.
If the Cylinder Projection is not at the bottom of the tool shelf, the plus sign should be there, and you can open the panel by grabbing the plus sign and pulling it upwards.
