Mapping an image to the inside of a sphere
I apologize if this has been covered before but a quick search wasn't yielding any answers or I didn't phrase it properly, so here goes. I would like to create a starfield image using the tutorial but then map it into a sphere. What would the dimensions of a panorama for such use be? Thanks in advance to any suggestions. Also, I apologize because I should have mentioned that I am using HF Pro 4 to try this.
