Seems to me the other bug is about slopes and this one about collision with NPCs, so I don't think it's a duplicate.

Collisions have changed with recent code updates, but I find I can still get by an NPC in the spiral staircase in the original engine when I can't get by in OpenMW.

Just tested an original game. It seems player in Morrowind does not have a collision box and can move inside another actors collision boxes. A collision based by mesh dimensions, maybe?

#10 Updated by Andrei Kortunov 9 months ago

Sorry for being unprecise. Morrowind does not show a player collison box if "tcb" was activated from 1st-person view.

But actors (or player at least) still can walk in another actors collision boxes, see the screenshot.

Additional testing results:
1) It seems Morrowind uses a mesh dimesions for an "actor-actor" collisions in interiors, but uses collision boxes in exteriors
2) A player does not collide with small creatures (such as rats and scribs) in both exteriors and interiors.

Looks like Bethesda's programmers used a couple of hacks to workaround some collision issues.
Should we replicate this behaviour?

#13 Updated by Andrei Kortunov 7 months ago

Can we just use mesh dimensions for any actor collision in interiors? Maybe this trick can help us to avoid stucks in mines, narrow towers, etc.

#14 Updated by Andrei Kortunov 7 months ago

Can we just use mesh dimensions for any actor collision in interiors?

From the other side, this change can break a range combat and magic.
So we can change only "actor-actor" collisions.
