Been having a weird issue, so in Blender my glasses look like this: https://i.imgur.com/A0rossA.png
Then when I preview the mesh in the uploader it looks like this: https://i.imgur.com/24KshLd.png
And after uploading it, then rezzing it, it looks like this! https://i.imgur.com/FdmtciC.png
Any reason why? I'm not sure what the issue is, I've checked to make sure that I've applied scaling and stuff in Blender so I don't think it's the mesh. Is there any way I can fix this? Thanks much!
