What does it look like in Blender without rendering? Cuz my imported blender models look like how they are un-rendered (either texture or solid mode. Forgot which).
What does the treasure chest look like from behind? Is there backface culling on?
Hi,
try select this flliped normals and turn them or select all faces and recalculate normals outside.
select automatic face smoothing and set about 35°- 38°
P.S
if you have single face for chest “walls” turn on faces double-side
