I have a question: will the new bones/fluid movements that redfaction is proposing possibly slow down the game? I imagine that there's a technical reason why EA has not given us hair that moves in the first place. Too many calculations? The need for a high poly avatar?
Someone mentioned the clothes would need to be weighted for his new armature, so, I'm really curious...
About the calculations, I'm not 100% sure about that but the number of polygons does not vary so in reality the game would continue to move the same data, also unlike TS3, TS4 is quite stable, I would bet that we would not have problems but I miss a little how things work inside the game engine
Yeah,it is right, every mesh needs to be weighted with the new armature if not the new added bones would not be work
Counting that each pants, shoes, shirt etc etc is a mesh that replaces the basic body mesh in the game, imagine but do not worry much about that, I guess that when the sims are dressed only the bones corresponding to the armature standard will be used so no bouncing out of the bed ;P
And about your other question, it can be done with a lowpoly mesh, in fact it's easier to do it, more polygons more complication but more fluid and natural results if you do it well
With the cartoon style of the sims it is not necessary to deploy a great technical boast, the result with the mesh of the game can be satisfactory
Personally I think that REDFACTION has been exceeded, with adding new bones that make the function of correctors for the deformation of certain parts of the body when bending was enough, and really some animators like Amra already use existing ones very well so ...
But if really you or someone else is curious about these aspects I think that redfaction continues here, nobody better to consult these doubts
