Look at this ... is my portal working ?

#1 Ok I got it working....

Here is my advice to anyone who wants to do portals in Constructor.

1. Follow all the rules that you see posted here in the forums:
--> geometry inside of the room that is portalized should be AIR TIGHT. No gaps anywhere. When in doubt, just re-build it.

--> The portal brushes should be 0.1 units thick. In other words, super thin.

--> The portal brush should be "buried" inside of the surrounding brushes and touching only 4 brushes total (top, down, left, and right) and the brushes it touches should be structural only, not detail brushes.

However, on top of all that, I should also add that the only way I could get it working (and this is in Constructor 1.0.6, is to make a solid geometry brush, then hollow it out. Then that the hollow inside is the room. Then make your openings using CSG subtraction. I know that this is very basic stuff but I had built everything in a much more free form fashion initially, and snapped stuff together using the build in grid snapping feature with 0.2 unit increments. Apparently, there were still small holes in my stuff .

Doing hollowing and CSG stuff is logical , and its how we had to do it in the 'old' days with tools like QuARK and Maplet, so it makes sense for portals, since the math has to be exact in order for them to work methinks.

So yeah, that's it. Write you if you have questions.

#2 Why should be the portals 0.1 units thick?

#3 Not sure as to the reason why.
