Hi, my first ever post here! I'm making a map for portal and I have an annoying issue:

I have a grouped func_breakable that is not breaking upon shot by rocket_turrets.

However, when I create individual func_breakables, it works. ( it is a curvy window made of 8 brushes (arch tool). Help me please..!!!! I could post a screenshot later on if needed.

Ungroup them. In the Break output for each one, have it break all the rest.
You can select them all to tell all of them to break all the other ones to speed it up, just remember to remove the one that breaks itself on each. And you will need to name them all. Or in the break event for all of them, make it active an env_explosion to shatter them all.

Thanks for the almost instant reply lol! I did what you said, and it worked perfectly. I think I will visit this site from now on a regular basis, lots of good maps out there.. I hope my map doesn't disappoint. How to make sure your puzzles are unique? I don't want to copy other people works :S

(My first portal map, but already mapped a bit for L4D, Tf2, counter-strike 1.6 and hl2..) Still, I have a lot to learn and I think this if the best place to

If your trying to make original puzzles, I know this sounds odd, but I reccomend you play some of the maps here. Seeing other peoples ideas can help you come up with ideas.
