The file can then be exported to FBX and Unity.ĭesign note: if content needs to be edited further, once rotated and set for Unity, objects can be (re)rotated back to their original orientation (in Object Mode – they will then appear rotated on X by +90 degrees, i.e. This fixes and resets the rotational value back to 0° – X now reads X: 0°. To do this, with the object still selected, from the Object menu select Apply then Rotation & Scale – Object » Apply » Rotation & Scale (alternatively Ctrl + A). Once the necessary rotation value is set the object needs to be ‘fixed’ otherwise the orientation data exported to the FBX will retain the original information instead of the update. This rotates an object lying on its back, upright. Step 1: in Blender select the object prior to export and in Object Properties rotate the X axis negative 90 degrees in Transform properties. Unity will use the orientation of objects at time of export from Blender so they may appear correct in some views and editors but not in others. It’s important to address this problem so object coordinates are consistent and universal, especially in relation to the more advanced aspects of development. Important: confusingly Unity also uses the location, rotation and scale of objects at time of export so they may appear correctly when dropped into the 3D View but not in the Asset Browser preview and/or Transform in the Inspector. X: -90°.ĭesign note: changes made to rotation are irrespective of an objects orientation in the 3D Viewport an object lying on its back or standing upright should be similarly rotated ‘backwards’. To fix Blender exported meshes being incorrected rotated in Unity, once an Object is ready for export to *.fbx, in Object Mode select and then in Object Properties or Transform properties of the Sidebar ( N), change the Rotation value of X to -90 degrees (negative 90°), e.g. The information outlined below is a fail-safe option that sets the orientation at source forcing Blender and Unity to honour rotational data baked to the FBX file. To fix this meshes need to be rotated prior to export in Blender.ĭesign note: the orientation of a selection can be changed at export in Transform settings but not reliably. However, because both Unity’s development environment and Blender 3D use different cardinal orientations – Z Up for Blender, Y Up for Unity – exported content is often incorrectly rotated around the wrong axis meshes that lay flat in Blender will appear standing upright for example. So, I am thinking maybe some kind of precision issue or maybe something at import time with assimp or something is being lost as there are 160 or so bones that are getting mapped, due to the new channels being created.Although Unity can import and work with *.blend files directly ( Blenders native file format) it’s often more useful to use *.fbx (FBX), largely because they don’t include extraneous scene data that has to be dealt with. One thing, the model works fine when imported into Unity. You'll see them as something like $Assimp_FBX$ and they won't have animation tracks. so it creates additional nodes to handle them. The one thing is that assimp can't handle offsets. I attached the FBX and a converted mdl using AssetImporter. Skinning math is kind of a kryptonite :) I'll have to read that article :) I've got around 10 hours into trying various things and stepping through the import code, ensuring weights, etc. I'll look for some more models that exhibit the Great, the ninja is very simple and may not show the problem Good ideas, I do have the fbx tool and have tried converting it. Thanks Do you have any thoughts of places to start based of the gif above? The skinning and animations are perfection at the origin :/ Does the tested scout model have very complicated or subtle Thanks, max format it a bit of a challenge.
