Mesh is always imported distorted

a few months back when i was trying to import ripped game files, it will always become distorted the larger it is. this is actually been pissing me off (i been trying to post on devforums for a few months)


for the past multiple tries i been trying to import different meshes through the 3d import. but if the map is too small, i would try resize it in blender.
i would use a car as a size reference then resize everything but the car

but whenever i do this, apparently
bigger = the more distorted


smaller = the more detailed

i been asking other people on discord servers for a solve:
the top #1 answer is that they dont know
other answers have been like using the remodel plugin or resizing the scale in properties (which still ends up much more distorted)
people with experience has said to cut the map up into other parts, or use special mesh to scale it larger (tho i have no idea how to do this)

even doing some research, i would always end with nothing
i cant find anything on it, or forums about it.
there are similar forums:
Meshes get Corrupted When Imported into Studio
or
Mesh changes when imported to roblox

but they dont solve the problem either.

IF cutting the map into seperate pieces is the correct option, then i have no idea how to do it (as idk how to use blender, too confusing)

its been annoying me for months, and i keep doing work on projects that never get completed as i cant even resize it to a proper scale.

I think its probably a floating point precision issue or some weird engine behavior, but there is two (unrelated) things you can try, Set the meshpart RenderFidelity to “Precise” if you havent, and in workspace properties disable “StreamingEnabled”

Both of those are performance optimizations that reduce the fidelity of objects in one way or another (Streaming does some interesting voxelization trickery and RenderFidelity can automatically generate LOD’s for a mesh)

i think i tried this before when i had some issues with a smaller mesh, while i was trying to modify a car hood. (didn’t solve the problem, just turns out i needed to recalculate the normals)
theres also a related post in the similar forums i listed
RenderFidelfity Issue
ill check it out and see if the problem is helped or solved

The biggest indicator of the issue is the warning triangle next to File Dimensions

Why limit your searches to Discord or Roblox forums for Blender help?
There are plenty of tutorials on how to use Blender. Google ‘Blender split mesh into multiple objects’ or similar terms.

theres tutorials for splitting meshes into multiple seperate meshes? tbh i actually didnt think of that, ill try and see if it works.

edit: umm apparently my pc crashed
