Hi, I am trying to create a crowd simulation using Unity 3D. How to get more (similar) characters move (run, walk, jump, climb stair)? Tried importing characters from ANIMA Lite but animation lengths are short. How can I create crowd simulation in Unity 3D using AI crowd navigation/ behavior tree in my case without using any other software? Please help.
Just to clarify, you have characters, but you are missing animations and the crowd behavior/navigation?
The navigation part is fairly simple - Unity does all the heavy-lifting for you on that end. You can either start by building a NavMesh and using Unity's NavMeshAgents (documentation here: https://docs.unity3d.com/Manual/nav-BuildingNavMesh.html), or you can look into using Unity's ML Agents ( https://github.com/Unity-Technologies/ml-agents ).
The animations might be a bit more problematic. I am assuming you cannot animate the characters yourself in Blender? You could try using something like Skele or uMotion from the AssetStore. These allow you to animate characters yourself within Unity. Alternatively, you can try to find walk cycle animations for free in various places. Try Mixamo.com or a few online marketplaces for 3D assets. Once you have an animation, Unity's NavMeshAgents can work with that.
Let me know if you get stuck or have any questions.
All the best.

You can create your own characters with Adobe Character Generator, then import them in Mixamo.com to add animations, export them in FBX and finally import to Unity
You can change the animation speed in the Animator window. You also can change the duration of the animation in the Animation window: just spread the keyframes
We are currently working on a new method to import fbx models with or without animations and connect them to preset or custom animation states in Pathfinder. Then you will be able to change animation state as part of the agent profile and switch the state as part of a behavior action. This is in active development now, so any feedback on this feature is welcome.
