Hey Blender users. I’m a fairly new Blender user (starting using it about a year ago, but infrequently). I’m trying to do my first actual rendered scene. I have this object made using a curve:
I want to know how to fill in the end of it? Is there a way in the curve properties or something like that?
Also, I want to know how to extrude an object along a curve. Namely, the circle you see at the beginning along the curve.
People have told me I can do this using the ‘Bevel Object’ in the curve settings, but when I click on that, it just pops up blank?
Thanks in advance! 
Also, one unrelated question that doesn’t need to be answered. For texturing things in Blender, do i have to create all of my own in Photoshop or something? How does texture creation work?
