[Bf-cycles] Cycles Standalone - tangent space normal map

Hello all,

We were trying to setup glTF PBR workflow using principled_bsdf in our Cycles Standalone integration. Everything is fine. The only problem is if we use normal_map node with tangent space, mesh turns black. We were testing using standard glTF model named Boombox from glTF repo.

I read that if subdivision modifier is there then tangent space normal map will make it black. But that's not the case in our cycles standalone integration. (We even tried with interpolation="flat" on mesh node if smooth subdivision could be an issue).
