Given the acceptance of "Cascadeur Full", with more than 200 downloads, "so counted by eye...", there is a software problem/defect "per se": there are NO graphics or filters to optimize the generated .fbx.
This, in an animation of 50 frames, results "in a nonsense"...
However, exceeding 300 frames, an animation of 4556 frames generates a ".duf" of 40 Mb...!!!! That is unacceptable, and Daz itself "crash"....
Although we can uncheck "not used" bones, the size is exaggerated when exporting...
I am making "templates" for different models, not the one from Daz, which is only for "Genesis 8 Male"... I am referring to an Autodesk "HumanIK" skeleton, or a "Unity" base..., apart from more "dirty stuff". These "profiles" are stored in C:\Program Files\Cascadeur\resources\autorig_templates, or the path of your choice...
At the moment, it doesn't support "Genesis 9", but it's all a matter of time... They are json text files, with extension ".grigcasc".
I'm not very involved, as my current work is more focused on scenery and translation....
By the way, the "Cascadeur" was given to me by an "old chap" who lives in Pakistan (in the city of Karachi...). He is a young talent, still in University, but in a FB group I knew him many years ago.
To the case! It is not the same in size and proportions a generic "Genesis8Female", than an "Alexandra8", "Victoria8" or "Babina8" .... For that, as the "Laylo3D", made his "templates" for each model....
