My 3D model in my 8th Wall project is rendering with black textures.
There could be a few causes to this issue. A good initial thing to look at would be optimizing textures, ideally the dimensions will be to the power of two (ex: 512x512, 1024x512, etc). I wouldn’t really recommend using anything over 2048. Testing with optimized textures is key for a smooth final experience.
Take a look at our documentation on the issue here: Black textures on iOS devices | 8th Wall.
You can also easily reduce texture sizes using the online editor here:
