Incorrect rendering on Android for bigger models #670

Hello, I noticed weird rendering on Android when the model is a bit bigger. On Desktop everything seems fine, the moment i switch to Android it becomes completely white. It happens when i resize the model, if the model goes over ~600 units in scale it starts rendering incorrectly. I provided the project with the sample scene that shows the problem. I also included the build settings for Android that I used. BigGltfTest.zip BuildSettings

Without having a deeper look: I'm afraid somewhere in the graphics pipeline you're hitting a floating point precision issue like the one in #75 .

Are you using mesh quantization? Any extreme values in transforms?
