So I'm using boolean difference on two models, one a Vue rock, the other an imported 3d model made with silo, and there's always little leftovers, little particles hanging in midair....I tried baking the models but had the same result.....any ideas?

And about the baking....does it matter if I bake the models before or after the boolean difference?

Can you show some screenshots? "Before" and "after". Could it be that you simply are not overlapping enough?

You have to bake the result of the boolean difference, not the models themselves.

Did you try removing the remains with another boolean difference, like suggested in another thread?

I'm sure they overlapping well enough, and I've tried moving ther rock around and it always leaves the same remains....Artur, could you explain again what you meant the other time about performing another boolean difference?

If you have a piece that you want to remove, you can create a cube, for example, overlap it with the piece you want to remove and do a boolean difference (object - cube). The cube can't be overlapping with anything else, of course. The result of the operation should be the original object minus the piece that was removed.

Yeh, Artur is right, that's what  I meant in the other thread when I said:
"but if worse come to worse you can try eliminating the extra bits by enclosing them in a primitive object and doing a bollean subtract, or enclosing the bit you want to keep in a primitive object and doing a boolean intersection."
Funnily enough, after saying I dont remember it happening to me I had something weird occurring with a boolean subtraction. I subtracted a modeled object (Hexagon) from a water plane. It 'ate' some extra bits of the sea, so I had some holes where there wernt supposed to be any. I was just going to hide them with other things, but the holes went away when i made some modifications to the object (including higher resolution). So I'm not sure if it was a hexagon problem or a vue problem.
