Any limitations on number of bones or animation dummy nodes

Hi Asobo! Happy holidays. Just a quick question, is there any limitation whether in the 3ds max or Blender exporter on the number of animation nodes that I can use. For example can I have 1000 bones in various skinned meshes along with 1000 dummy nodes ( point helpers ) in a model. If so would this cause any major performance impact. Thanks!

My two cents

The documentation has several references on how skinned mesh (bones) are heavy on CPU and should be avoided when not needed (e.g. distant lods)

https://docs.flightsimulator.com/html/Asset_Creation/3D_Models/LODs.htm?rhhlterm=skinned%20skinning&rhsearch=Skinned

There was a recent case, user added lot of animated trees (with several hundred of bones in it), and eventually the game came to a crash

So the idea is pay attention to what it worth using precious resources :smiling_face:

(1000 bones in the scene are not a lot, a base character without fingers has roghly 30 bones, so a airport lounge with 30 characters will quickly reach that number ), add to that all the workers on the terminal

Hi. Thanks for the input. Those numbers I listed were just random but it makes more sense now. This is for an aircraft not scenery but I assume the same still applies.

Hi @BlueBirdSim ,

You can include several thousand bones without any problem, but keep in mind that the more animations there are, the more significant the impact on memory will be.
