wall run/clip bug

[JeffBobbo]

Seems there's some issues when transitioning from clip material to geometry where you get stuck kicking off an invisible wall.

this is caused by placing material in an odd way inside of the geometry, also mentioned here

if you use the proper sized cube (or remove all the unused materials from inside of the geometry on that bloodlust wall) it doesn't occur.

Yep, I experienced the same thing in my Center re-vamp. Some really weird shit is going on. https://drive.google.com/file/d/0B8LVgU2QCQy0aW96VjRvQnJZX28/view?usp=sharing

I copied over the geom from alpha to omega, or vice versa, can't remember, so both are EXACTLY the same geometry and material. And it happens on one side but not the other. Same thing for the side windows.

This isn't just on bloodlust, it happens on lots of maps, this was just the easiest to reproduce. Also, I believe the engine optimises materials into geometry if it makes no overall change (and this is easily testable), which makes this unfixible by modifying the map.

[shirepirate]

i just fixed your exact example by modifying the map.

[JeffBobbo]

@shirepirate I just checked my version of the map, there's no clip material inside the geometry. Could you explain your 'fix'?

[JeffBobbo]

@shirepirate done some testing, I managed to 'fix it' by adding clip material to that piece of geometry, but when I then recomputed the light map it is was removed bringing the issue back again.

Given that this issue is present on multiple maps and isn't easy or intuitive to fix, can you please reopen this issue so it can be fixed properly?

[JeffBobbo]

This is also effecting some other maps maps which I just tested:

• battlefield
• biolytic
• bloodlust
• deli
• pumpstation

There are possibly others, I only done a quick check.

[shirepirate]

will have the engine guy confirm if this is an actual fixable issue or not

I think this more has to do with how we're doing the angle tests. Will require some major testing on my behalf, so triaging for now.
