I agree. Started out with the 'wrong' dimensions. The whole volcano is actually only about 500m wide. On this next try the trees are already reduced to 0.7 times their original size and then again sizes from 0.4-0.9. I think I'll start from scratch with world sizes for the volcano (which I might want to make differently anyway, perhaps WM), or reduce the trees more if necessary.
I am now struggling to get the cloud cone right (softness distribution, angle, angle smoothness, starting height, width, cloud settings); it's getting more complicated the more I want to refine, and I actually would like to keep it simple (for my own sake, or I won't understand anymore what I did yesterday). Will be followed up...
Perhaps I should call it 'Baby Volcano'.
