Use Capturingreality Model with Unity and Vuforia

hi 

I create a 3d model with capturingreality software and import  fbx file (64k mesh) in unity for AR project

but  In AR application when 

camera is far to target  :   3d model have a noise, like this image : 

and when 

camera is near to target :   3d model haven’t any  noise , like this image :

 

I test this issue with another simple 3d models but  this problem is just with capturingreality 3d model

I would say this happens when the automatic optimisation is running (LODs) To prevent such effect, I would try increasing the Gutter in the unwrap settings of RC. Basically what seems to happen is the UV islands start to overlap since they’re by default very close to each other. Increasing Gutter will increase the space between two islands.
