Why Ue4 crashes?

Hi!
I’ve tried to import a 3d model from 3ds max to UE4 and it’s worked fine, after that I created a LOD for my object and my engine crashes all of the time when I’m tring to import.
Here is my crash info:

Hi Rugabi,

When you’re importing the mesh can you disable the auto-generated lightmaps option? If this fixes the issue, this is a known issue with some FBXs but not all and you will need to setup custom lightmap UVs if you’re using it as a static mesh.

If that doesn’t solve the issue, can you tell me how many LODs you are currently using in your Mesh? The max is 4 (Base plus three lower LODs).

Thank you!

Yes I disabled it. FBX Static Mesh Pipeline in Unreal Engine | Unreal Engine 5.1 Documentation here is the tutorial what i’ve done it, but I’ve tried to open in Visual studio the fbx file and it’s samely crashed

Is this on any FBX with LODs or just this one?

Also, would you mind providing the asset in question or a test asset that can reproduce the issue? (You can send privately if needed) I’d like to take a look and see if anything stands out that may be the issue. Are you using 3Ds Max, Maya?

Thank you!

Hey, I’m using 3Dsmax, I’ve tried with different object and it’s alowed to import, but not really correct. Btw how can I send you a private message?

Here is my object settings; I selected the objects, created a group added a LOD , created a new set, here it is: a simple box e.g. I would like to create a collision like I’ve import it and walking between the boxes.UPDATE: here is another example, I’ve placed some boxes and I would like to walk between them. but as you see the collision of them is a big purple box, and I cant…
But after I import the collision is:

Can you tell me how many LODs you are currently using?
