Hi
Well I'll try to explain what happens to me with the editor:
- Yesterday morning, just radar mesh extraction from the room QR1 (with local settings enable) -> OK
- Opening with blender -> OK
- Backup without any changes-> OK
-import into the editor-> error (one posted above)
- Yesterday afternoon another attempt: can not reopen the room QR1.GR2 ?

- Try to open my file with my edit additional textures QR1.GR2> recalculate CRC

-> OK. opening-> OK
new-tries, with the original QR1.GR2-> will not open !

I then preview that after closing the editor it continue to operate

(in the task manager) -> Ok it's not too serious, but it eats memory
Last night, still can not reopen the original file QR1.GR2! but the other. GR2 open without problem
-This morning the same! OK I delete the folder how I unzip the editor and I reextracted the editor
- Opening QR1.GR2 original with the editor -> OK? It works !

(but the editor continues to function after its closure)
- Trying to extract just the wheel of the radar-> Ok Opening with blender-> error loading

!
That's all for now, I'll keep trying all this
Ps:Super ,if you can add dds format for the export ! Do you need my .obj mesh after save with Blender ?
