I get this error all the time i try to upload an high poly scan obj (150 ml polys) on my 64gb ram laptop.

Trying to resize TArray to an invalid size of 2147562356

Anyone know how to solve this crash and finally load the model in my scene?

Thank you.

Could be that the TArray for meshes is using int as it’s index which max value is 2147483647

Try splitting up the mesh and importing in 2 parts.

It was a pain in the ■■■ to split the entrie model in parts but… it works!
I can even load an higher polycount mesh now.
A so simple solution, but so effective.

Thank you.
