I'm trying to create a room with doorways and walls and have it behave as you'd expect. I have a separate very simple physics model. It looks great in the preview window: the yellow collision areas are right where they should be. When I upload it, SL seems not to use this physics model, but to create its own that envelops the object. Since it's a room, this means it makes a big cube you can't enter. I attach pictures of the room (in SL) and the physics model (in Blender). The room is in two parts-- floor and walls. The floor part is OK. The physics model shown is just planes, but I've tried cubes and they don't work either. When I had the walls and floors together, same thing. Is there any way to tell SL to really, really use the physics model I provide?
Well of COURSE I figured it out AFTER I got all this typed. It IS that mesh wall prim addition which while I have been using that same "mesh prim" for a year or more with no issues IS an issue with this. So I am going to make a new mesh wall the same as the one there, upload anew and hopefully that will fix it. OR I may have to use an actual prim LOL. I'll write back here when I figure that out. I was retesting a house just now -- one that had passed all tests a month ago including my tall friend getting in and out of doors and up the stairs. Now the stairs still work fine for me, but HE cannot go up them any longer. I even went so far as to drag a copy over and make the house MUCH bigger (too big really) in an attempt to see if he could get up the stairs. Even with WAY more headroom than show in the photo he can't get up the stairs. I am 2 meters even. He is 2.32. (Keep reading :D) Confused. LOL. Especially when he could get up the stairs a few weeks ago. He has not changed his height; seldom on anyway :D. AND IT GETS MORE CONFUSING. After doing some tests I found that if I take a copy and then rez, the how while it SAYS it is "prim" is acting like convex hull. The minute I select it and got to "edit linked parts" (NOT EDITING AT ALL > just setting to that) the build is fine. It turns out that while "I" could walk up the stairs, I couldn't walk down the stairs. Until I did the edit linked part thing. BUT that same building "fixed" could not be dragged over with shift copy OR copied to inventory and then rez. It once again reverts. This is the same very pretty house that had the can't rez on the floor because of the added after the fact mesh walls (and that never has made sense). I am going to keep trying to figure this out but if anyone has had this issue and found a solution, please chime in. Thanks.
