Ah ok, if your english isnt very well, its ok .
I think i understod your problem. THe only strange thing is, i cant reproduce it.
Thats very anoying. What i do when enetering a side or ceiling door is:
Climb up(side door), open it, climp higher(so feets are above the uper corner of the opened door) and than i enter(with ducking of course).

When i get stuck inside a closed door for example, its always possible to open it. And sometimes the engine itselfs pushes me out.

Maybe you could do me a favour and record a video?

WHOHOO :D, got your problem(at the side doors). I think what you do is:
Climbing up the ladder,opening the door, "jumping" onto the opened door, moving at least one step forward without ducking(here i got stuck in front of the door inside the wall). If you go a similar problem at the ceiling, its still strange(not yet reproduced) but now iam on the problem with the side doors.

Yep, problem is exactly as you sad, never tried to duck in doors But sometimes even without ducking I could get in next cube, so u better check players collusion box. About video, we'll see

Got it, checked the box and my problem was, that i tried to be TOO exact XD.
Cause the Box changes during ducking, i had do specify the box manualla(to have more controll). Well, for the duck box, i did everything correct. X and Y axis had the same size. But for the stand box i did it wrong. I used a lower X numbers.

You should see it in the pics below:
[WRONG BOX]


[CORRECTED BOX]



I'll upload a fixed version later. But as far as i can see, thats all i had to change. nOw everything seems to work fine.

I had the same problem in my game, do you use c_updatehull? It has some problem, when your model has too much animations, and if you want to change durring run-time collusion box from some frame, it makes it too big and wheird %) So better change it youself by min_x,min_y,min_z With friendly greets 3RUN

I used min_x/min_y/min_z.

But i set it manually too perfect .
For the ducking i set the base to a quadratic shape(cause i got problems with rotating inside the tunnels). But i didnt set the base of the box to a quadratic shape. Now it is
