Importing Blender Into Unity<\/h1>\n

Since I’m using Blender<\/a> and Unity<\/a> for my current projects, I’ve had to figure out a common problem with this integration.<\/p>\n

Right-handed… left-handed… up is forward… forward is up… dogs and cats living together.<\/h2>\n

There are a bunch of posts about importing models from Blender into Unity, and how they always come in rotated incorrectly. Blender is right-handed with (right, forward, up) orientation, while Unity is left-handed with the (right, up, forward) orientation. The primary axes seem to be forward and up, since the objects rotate around the axis that bisects those two.<\/p>\n

Basically, you want your Blender model to face forward along the z-axis and up along the y-axis. This causes your model to appear to be pointing up in the Blender workspace, which is not really how you want to work on things. Blender has the ability to distinguish between applied rotation and displayed rotation, which I use to fix this apparent problem.<\/p>\n

After researching and experimenting, I’ve decided to use the following method. However, I have not attempted to animate any of my objects yet, so that may not work properly. If animations, or any other feature, breaks this method in the future, I will update this post to reflect the fix.<\/p>\n
