Hey everyone. So this afternoon I was having some trouble importing a gun mesh into studio. The mesh is 3 separate parts and they look perfectly fine in blender. The unfortunate part is when I import the mesh parts into studio they appear to be glitched and incomplete in a way. Here are some photos to help you understand what I am saying.
I have tried re-importing but I am not sure what to do. If someone has had this issue or know’s a solution I would love to hear it. Thanks!
This is a very common problem among Blender 2.8/2.9 users since it does not show where normals are facing. Just select everything in edit mode and do Shift + N(to all 3 parts), it should recalculate normals and flip them outwards.
I’m not a mesh expert, but the property “Double Sided” when made true should fix it.
Alright, when I click Shift-N, do I just select the “inside” check box?
How would one make the “Double Sided” feature true.
By checking the box, the technical term for it is making it true/false, sorry for the confusion lol.
All good, thanks for the clarification!
