Exporting models into .alo files from Blender

Fixing possible export problems in Blender


 * The object transformation (position / rotation etc.) problem
 * Tansform the mesh in object mode
 * in object mode go to the Object menu -> Apply -> All_Transforms (or Rotation etc.)


 * Bone rotation problem (in Edit mode individual bones rotate around their mid point, not their head)
 * in object mode select the Armature
 * go to Pose mode
 * rotate the bone
 * Pose -> Apply -> Apply Pose as Rest Pose


 * Non-manifold shadow mesh problem
 * after trying to export a model with a non-manifold shadow mesh, you'll get an error message in the bottom right corner of the screen, click on it to read it
 * to check non-manifold vertices select the shadow mesh in object mode -> go to edit mode -> Select -> Select all by trait -> Non Manifold (or press F3 and type "select manifold")
 * fix the selected vertices by hand or
 * try Edit -> Preferences... -> Add-ons -> Mesh: 3D-Print Toolbox
 * in the 3D-Print menu (it's around the ALAMO menu) -> Make Manifold

Autodesk 3DS Max
