I’ve recently started having trouble with importing meshes using Shade Smooth + Auto Smooth into Studio, which I’ve not experienced up until a few days ago. It imports perfectly with Shade Flat, but I would preferably like to use Shade Smooth + Auto Smooth.
I’ve tried using the Edge Split modifier instead of Auto Smooth & Solidify modifier, same result as before. I don’t want to use a Sub Modifier & Insetting as that adds a completely unnecessary 1.5k tris to the 108 tris sign.
Images of the mesh in Blender and the result when imported into Studio:

I don’t know the cause of this and it’s bugging me so if anyone has an idea on what causes this and/or a potential fix please let me know and I’ll check it out. Thanks for reading.
