Hello, i’m currently recreating a map that is supposed to be carved in the rock. So, i was wondering if creating a big additive block then using subs to carve rooms inside is a bad idea ? I mapped for Day of defeat a long time ago, and i was avoiding the carve thing as long as i could, to avoid performance issue.
Now that engines have evolved, i was wondering if this was still to be avoided or not.
But in that particular situation, it would save me a lot of time !
I think it shouldt cause any problems -> after you are finished just convert your brushes to a mesh 
Thanks ! it was way easier that way !
By the way, i was going to ask you this : “is it possible to make all the stuff with additive block (lets say only the rooms block, withouth sickness), and flip all the normals of the selected objects ? I see the “Flip button” in the edit geometry tab and make it a room that way?”, but i just gave it a try before posting, and it works. And i think it’s even better than the previous method !
Edit: just tried with several brushes, and it doesnt work. Only one will appear correctly
Hi,
My quick-blocking routine for stuff like this is:
Us an addidive brush, but make it hollow.
Place the “rooms” next to each other, then cut out the door with a subtractive brush that has the width of both walls.
Thats just three brushes then for two rooms, incl. doorway…
Cheers,
Klaus
