Your program looks very interesting, but my web browser did not like the link. Is there another way you can put the files up so "nonmembers" of any site can download them?

First, I must say, this program was NOT created by me, I just found it upon searching, and put the link here for everyone :) the credit belongs to the creator

Here is the download site: http://www.gamefront.com/files/21775902/screwValvesEntityLimitInPortal2_zip

Got it. Testing now...

Have fun :)
I used this "limit-break" stuff to create this test: (just an advertisement lol):

It worked like a charm. I will post my updated chamber when I finish on the test you have provided.

Well, this is currently working perfectly... But you should be careful when you use it and you know you are over the limit : always playtest your maps a lot to be sure that the lot of items will not cause bugs or lags ;)

This is the one I used this program on

@Geneosis I always test my maps, the only problem is I can't always assume the testers have a graphics card as good as or better than mine.

Yeah, same for me... That's what feedbacks are for ^^ I hope people having trouble will post it in the comments of the map ;)

I'm adding light and other things to my "Turrets Corridor v2.0" can I use your fireworks technique?

Sure you can use it ^^ But it's better to make fireworks in a totally dark room ;)

You remember the map with 5 turrets at the door? I'm redoing the room with the funnels that pick the turrets up. Not quite dark.

Well, yeah... Maybe change that parto fo the puzzle ^^ Or use it in a white room, you will see...
