hi, everyone

I’m studying annual daylight simulation using LB+HB.

I try to use bsdf material in this sim.

I have a error.

if i change other material, this sim can run.

someone please tell me advice.

Daysim can’t handle BSDF material. Check this discussion for possible solutions: [https://github.com/mostaphaRoudsari/Honeybee/issues/563](https://github.com/mostaphaRoudsari/Honeybee/issues/563)
