CTZn : If I upload a igm file with no medium, would it be ok? That's actually a simple solution
Mmmh now I believe that my request was hasty.
A sole specular in IGM format would be more trouble because while MtI does link to (include
) external files it does not import them as parametric nodes currently. Presets in Maya are applied to Maya nodes using Maya's Embedded Language, requiring the migration of the private data as a string.
The current solution is the best to preserve the products definitions as provided by SGG. Perhaps an alternative will exist in the future, meanwhile we should wait for Glare's fix for the "medium defined twice" issue.
Thank you for your concern Etienne, please pardon my little mind ! I should have referred to Glare in the first place.
