Old box (Low poly) model with PBR textures.
The OBJ model has all textures already. Look Game Ready file.
The textures were created in Substance Painter and included in the archive.
In any case, if appear some problems all instructions how to import textures in Blender are in a a ZIP archive.Look pictures 1,2,3,4...
If something went wrong, send me a message.
I can add to this model defferent changes for an aditional payment.
Errors fixing is for free.
