I don't know if they are easy, but fun, and worth the time to learn. I never read directions, I just push buttons to see what they do, I learn better that way. There are so many programs out there, I can only tell you what I use, because I don't know about the others. I use paintshop a lot, photoshop a little, Bryce (free download) can get free obj (objects) through ShareCG.com, I use daz, the free downloads, and I get a lot of free things from ShareCG as well. Model making, you might do search either through internet, or even here .
