I think i'm going nuts.....
1. i build a new house, then i used planes for the physic.
2. Then i started working on the second floor. Just copied everything and modified it.
Everything so far fine, i upload the Physic file without analyze.
Now i started to add a hole in the upper floor for the stairs. Looks good and then i uses again planes for the physic. But can't get it to work....the physic allways looke like a convec hull. I tried everything...i uploaded it alone...only one object with the physic....it's dosn't change.
Right is the visual Model with the hole for the stair, and left is the physical model.... in SL it looks like in the picture above.
(i moved them appart to see it better)
Anyone a idea why i have problem with a simple hole when walking trough doors is no issue at all?
