Arcore-unity-sdk: Unity ARCore Strange Bug

[pIuszak]

So I'm having the strange bug with ARCore where I'm showing Engine in AR and my App suddenly stops refreshing and blurs the frame (see photo).

My issue, however, is happening occasionaly in different angles and model configurations and same code and assets are working perfectly on ARKit.

I've tried to track this in console debbug with no luck, no errors.
Can this be a model failure ?

Tested on multiple Galaxy S7

I’ve experienced the same issue on the Galaxy S8 and Moto Z2 Force.

It appears to be related to graphically complex scenes with high poly count, draw calls, and/or skeletal animations.

It also appears that AR tracking is affected by these glitches, as the background image will freeze, and display an incorrect pose when it resumes.

No high poly count 1.2k Triss / 2.3k Verts
No skeletal animations
Tried with simplest materials and lightso no draw calls problem, maybe the model issue ?

[sam598]

Does the model, or any part of the model, have a negative scale value in any direction?

I think this is related/the same to #169

Hi @luszukpawel do you still experience this issue? I don't have enough evidence to think this is an ARCore issue, did you try rendering your model without ARCore but on Android?

Wow, it was really the negative scale problem.
thank you very much guys<3
