set(my,POLYGON) is the same as my.eflags |= POLYGON and I tried it already but it doesn't work.
However I splited the model into three cuboid-shaped models and now it works. But it's strange that i can't make a collision hull that corresponds the real hull of my model...

did you try not including narrow and fat, and just going:

my.eflags .. POLYGON
wait (1);
c_update....

While you set(my,POLYGON), you should omit
the FAT and NARROW flag, then run the level
and press F11 twice, if you don't see a
bounding box (blue color) surrounding your model
then you're done correctly.

I agree, it works just like that for me as well. I use polygon flag on alot of things.

Yes I tried not including FAT and NARROW and it didn't work.
But I just tried writing
my.flags |= POLYGON;
instead of
my.eflags |= POLYGON;

That's my action now:
Code:

---

action Drehkreuz()
{
	wait(1);
	my.flags |= POLYGON;
	c_setminmax(me);
} 

---

When using FAT or NARROW It must be "eflags" but when using POLYGON it must be "flags". Now it works without having to split the model

Actually I see a blue box surrounding my model, but it works.

Actually, you don't need the c_setminmax(me)
