Importing big mesh modify physic behaviour

Hello guys.
I created a gliding effect for my character.
It worked very nice , I was testing physic behaviour falling from a high to a lower platform.
After that I created a big glb mesh using topo export site and imported into my project
It looks like this:


Now I can notice a very different behaviour on the gravity force applied to my model when falling.
Result:
No big map : character can glide.
Importing big map: character can not glide , it falls very fast.
Hope to be clear about the issue and have some questions.
Is it normal ? (perhaps bbjs calculate the world size to fix some havok behaviour)
if so … perhaps I just need to tweak applied forces.
Is it some performance issue ? how can analize it ?
Regards.

Hi @Leandro_Roggerone

Did the framerate change? I don’t think of a float precision problem. Maybe a bug in some conditions.

Can you please repro in the playground? it will make debugging much more easier.

Hello @Cedric , fps counter shows:
around 30 when big map is enabled.
around 50 when big map is disabled.
around 60 when disposed.
Btw: I never consider this counter before.
What do you think ?

Regarding share on pg … I will work on that but it will requiere some time.

I solve the issue creating a single merged mesh for main componentes, ex.
trees , roads , buildings.
Now , fps is at 60 again and the game run smootly again.
Thanks
