Describe the bug
At some point while testing the new version of the BSDF transmission was working, however now it's completely black in the microfacet lobes, and appears to be slightly incorrect with respect to total internal reflection in the delta lobes
Derpius commented
Eval/pdf still broken, likely due to inverting TBNs on backface hits
Derpius commented
EvalBSDF/EvalPDF doesn't work specifically on backface transmissive rays

EvalPDF works
