I am using houdini to create a skeletal mesh (humanoid) that I intend to retarget to unreal mannequin skeleton animations. I have run into an issue I wanted to share and maybe get some clarification if anyone knows.

If I export a standard height human from houdini to unreal and select 100 to scale it as recommended, the mesh is scaled fine but the skeleton has 100 scale. This blows up when trying to retarget. Solution at the moment is to remake skeleton at larger size in houdini so when I import into unreal I do not have to scale. I tested this with a quick box and a few bones and it worked.

ps. I make sure all the bones had the transforms reset so it was not related to bad transforms on the bones.
