I'm trying to crank out my first hurricane and from what I've gathered on the forums I need a high res image of a hurricane to use as an image map shader. I have three questions:
Is one image enough or should I have multiple images for multiple layers of clouds?
Do I want the image, once its photoshopped, to be black and white or have shades of gray?
How big is too big? Currently I'm working with an image 5600X7200.
