Hello and Welcome
Can't help much with UF - I never got along with it too much
It was it's animation set-up that turned me off the most - If only it would render animation frames as they finish, I might have taken the time to learn it better, but I bought it to render out a 7,000 frame deep zoom for a commercial project and was shocked when I discovered that I had to wait weeks to even get started on my video editing!! (I never saw any animation software act that way when rendering images, only when rendering an avi or other movie format)
Whazzizname was very nice when I complained about this, and promised to fix it such that the images would be available at least in "chunks" as the render job proceeds instead of making us wait for it to finish.
I hear an update came out, but never heard if this was addressed in the update - so never got it. Even though I really should just because I bought the program, but frankly - it's worthless to me in it's crippled state.
There's my obnoxious take on UF - no offense to those who like it! I just go off on that rant whenever I hear people talking about animation in Ultra Fractal...
Now Mandelbulb 3D I can help with! Do you have any specific questions?
