Hi,
I’m experiencing the following severe errors when changing either the transmittance or reflectance values to something else than the default in the HB Blind Material 1.2.0 component.
** Severe ** WindowMaterial:Blind="BLINDMATERIAL_44D10FBF", Illegal value combination.
** ~~~ ** Slat Beam Visible Transmittance must equal Slat Diffuse Visible Transmittance
** Severe ** Errors found in creating the constructions defined with Construction:AirBoundary.
** Fatal ** GetSurfaceData: Errors discovered, program terminates.
The error states that the beam and diffuse transmittance must be the same, but they are the same according to the blind material:

Anyone know the solution to this problem?
