Hi Mingbo,
Yes, I tested it right away and it worked with HDRs. The LB 1.3 has also the FalseStartToggle which was a nice addition.
I had installed LB 1.3 in early september and then followed the instructions of Chris. In Food4rhino it showed a more recent date for LB 1.3 (14 September) and used that file this second time for installation. Maybe it had something to do.
Thanks,
Arlind
