Odd display behavior for model on smaller screens

(Mindless Pursuits) #1

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:


Hmm, weird.

I turned off transparency on all your materials and it seems ok now...

@stephomi ?

That IS odd. I wouldn't have expected that to be an issue. I still crash sometimes when going to HD. I'll keep playing and keep an eye on transparency. Thank you for the help!


It's probably a rendering bug on iOS.

I suspect you're right. I'm going to mark this as fixed. Thank you for the assistance!

Depending of the textures size, HD can be pretty huge and can easily exceed the total VRAM of your GPU, so it's not really surprising.
