I am trying to export glucose.pdb using collada 1.4 format, to include it into an Ibook for my students (Ibooks author only allows .cae files).
The whole process seems to works great (without changing any default settings) but when i import the glucose.dae file, the molecule appears in grey color.
I am also hoping to export models created using ePMV in C4D as Collada files for use in iBooks Author, but so far I haven't been successful. Would you have any tips, advice or strategies for doing so? Any resources you found particularly useful? Also, have you tried anything beyond the default free/vertical/horizontal object rotations?
