Sweep object and proboolean mapping problems

[tricky]

I sweep a simple rectangular object along a path and generate World UVW mapping on the fly. This creates the correct mapping for the object as I want.
When I run a proboolean subtraction on the object to remove some cutouts, the mapping is lost.

How can I keep the UVW mapping from the original sweep object?

Try collapsing it after the sweep and then do the boolean.

I'll give it a go - thanks for the tip.

Just tried that and it makes no difference. Any other ideas?

Right, I seem to have solved it and the answer is: Don't Use Probooleans.!!!!! This is the first time I've bothered with it and it doesn't work properly - great!
