I created a 3d character(the grey guy on the video) on blender and added some animation to it, i exported both skeletal mesh and animation seperatly, when i moving with my player its seems like a giant baloon starts to grow around him and starts to collide with my character,camera, etc.
Note: The gray guy jumping is my blender character.
Next, check the collision channels of the animation’s mesh. See if the Trace channel for Camera is set to block, if it is, change it to Overlap or Ignore.
