[Question] Overlapping Brushes

[ManyPopes]

Hi guys, I'm new to making surf maps and just wanted to know whether I should leave brushes overlapping?

It's obvious that vvis takes an age to compile maps with overlapping brushes but with all the curved geometry in the map it's near impossible to join vertices properly. Will this affect the quality of the finished map? Or does it only affect the compile time?

func_detail

however, this is a bad place to ask mapping related questions. idk if there are any competent mappers around here.

I think it affects waterindicies.

Ahha, forgot about func_detail..

Thanks for the advice guys :)
