Hello,
I had a problem with exporting character from Blender to UE4, when he was in scene he was scaled properly but when I open my physic asset he looked like this:
So here’s what you need to do to fix this
Open your Blender file where your character is, then go to Scene in the Properties editor and change Length to Metric and Unit Scale to 0.01
Then Select Mesh and Armature in View Editor and make sure that Armature is parent to Mesh.
Press Ctrl+C(3D cursor will snap to the center of scene) and change Pivot Point to 3D cursor.
And Scale for 100.
After that select mesh then apply scale then select armature and apply scale too.
You will see that your Animations will broke now. Now you need to open Graph Editor and Dope Sheet
Set Current Frame to 1 on the x axis and to 0 on the y axis like this
Now select all your bones in Pose Mode and move mouse over your Graph Editor and press " . " (that will snap 2D cursor in Graph Editor). Now in Graph Editor you will find Search text box, there you will type Location (that will hide your rotation and scale points of your bones on graph). Select all points on Graph with " A " and Press S (for scale)
then press Y (to lock scale on Y axis) then type 100. Do this for all animations you have.
Thank you for your patience, It’s a little bit complicated but I hope I helped you.
