Fix #262
By adding a log in GLTFMaterial.cpp in "getMaterialPBR" method we got :
Diffuse alpha: 0.1, Transparency value: 0.1
Diffuse alpha: 0.01, Transparency value: 0.1
Diffuse alpha: 0.001, Transparency value: 0.1
Diffuse alpha: 0.0001, Transparency value: 0.1
Diffuse alpha: 1e-05, Transparency value: 0.1
Diffuse alpha: 1e-06, Transparency value: 0.1
Diffuse alpha: 1e-07, Transparency value: 0.1
Transparency was applied to diffuse alpha when we get material of each primitive.
There is a problem when object share same Material, material transparency is stacked.
