I'm new to Sketchfab and relatively new to making my own 3D models, and I'm experiencing a behavior I cannot figure out the cause of. I created my coffee mug in Blender 2.78, UV unwrapped it, made certain my scale was applied, then exported as an FBX. I then imported it into Substance Painter and textured it and baked it. I exported the textures to Unreal Engine 4. In all of those environments, the model displays cleanly and looks good.
I then found out about Sketchfab and joined, and uploaded the model. On a desktop, it looks great in the browser, but on my iPad, it has issues. In landscape view, it displays with a lot of green lines showing through the picture side of the mug. If I try to go full screen or turn on HD textures, it crashes the browser tab. This is true in both Safari and Chrome. I have tried reducing the texture sizes to 1024x1024, changed the normal map mode to OpenGL, re-
exporting the FBX, and re-painting and re-exporting from Substance. Nine have solved the problem. I'm at my wits end. Help?
Here is an image of what is happening in landscape mode: https://www.dropbox.com/s/xwt0evlg7l9cdp2/IMG_0332.PNG?dl=0
