Blender Import - Sub object at wrong location in Unity

Hey there,

I've created a simple barn in blender and when trying to import the blend file directly to Unity I've noticed that the door is at the wrong location. Instead of the front right its at the back left.

Here is what it looks like in Blender:




And here what it looks like in Unity:



Anyone has an idea about this behaviour?

 

I was able to solve this issue by resetting the rotation and scaling in blender.

Unfortunately I have another problem with blender files. When I create a simple object like an pickaxe for example I will end up getting weird scaling and rotation effects with the object when I child it to an empty parent object. Here is what I do exactly:

1) create a cube



2) Adjust the size so I end up with something like this:



3) Adding two cut loops at the top



4) extruding both sides 3 times



5) Moving the verticies so it looks a little bit like a pickaxe



-> Continue with the next post to this thread

 

6) Reseted rotation and scale in blender



7) Import settings in unity:



7) Object in Unity scene:



The first thing to notice is that X rotation in unity seems to work, but y as well as z both seem to rotate the object around the y axis (world). As soon as I child this gameobject under an empty object the rotation seems to be fine, but the weird rotation problems apply to the empty object then (which I'd like to rotate later on).

Any one has an idea about this?

 

Suggestion: Don't scale your objects in Blender; leave them at scale of 1. Instead, go into Edit mode and scale the mesh geometry. Same for rotation and translation.

Also, I've found it works best if I use the "apply transforms" to my objects before exporting from Blender to Unity (control-A shortcut key).

Generally, I've had the best results by building pieces in Blender and then prefabing them in Unity, rather than trying to build the entire hierarchy in Blender and exporting all at once. The FBX export can be told to only export the selected geometry. For Unity convenience, I make sure the origin point of each Blender object is 0, 0, 0 and their scales are all the same at the object level (but mesh geometry is whatever size it needs to be).

Prefabbing in the Unity part of the workflow, instead of upstream, also allows you to use your individual objects more flexibly without going back to Blender.

Hope this helps.
