My Problem
I can’t seem to figure out why some parts of my mesh are missing when I upload it into roblox studio. I’m still new to blender and just recently started to import meshes into studio.
Is there something that I missed that I am suppose to do on blender to fix this? Please let me know what I am doing wrong here.
I’ve been experiencing the same problem.
Go into edit mode on blender, select the entire model and press “ctrl + shift + n”.
There are many possible explanations:
When I do that the mesh doesn’t even upload at all.
Actually I think it was “shift + n”.
Press Ctrl+N, this should flip your normals the right way around. If they’re shaded really dark on the outside, then they’re facing the wrong way.
When I do “Shift + N” and try to upload the mesh nothing appears at all.
Select the whole mesh by pressing A , then try ctrl + N .
Make sure you select all the verticles on edit mode press “A” then press CTRL + N and something in the bottom left corner should pop up if not then it should be named “Make Normals Consiles” something like that and if “Inside” is unchecked you should be good. Just uncheck and check again to make sure the normals are good to go 
Just now tried that but it doesn’t even upload the mesh.
Ok. are you saving it as a FBX or OBJ? doesn’t matter…
I save it as FBX all the time.
