I have started using Bongo 2.0 with Rhino 5.0 recently and I am impressed by its capabilities. Unfortunately, I systematically experience a Rhino crash whenever I try and assign a keyframe to a selected spotlight object.
I found a workaround by defining a point light instead of a spotlight and assigning it a keyframe before changing it into a focused light. Nevertheless, I am wondering whether this issue is also met by other users.
Config: Windows 7 (64-bit) SP1, Rhino 5.0 (5.1.20927.2215), Bongo 2.0 Release 15, Brazil 18.104.22.168 beta (64-bit)
Hardware: Intel Core I7-3940XM, 24 GB DDR3, NVidia Quadro K4000M
The same here, with any form of light (I don't use Brazil). No problems in the x86 versions (Rhino 4.0 and 5.0) though.
We've tracked this bug down, and it'll be fixed in the next Beta.
