Setting Correct Axesīefore we dive head first into this, we need to correctly define the transform axes we will be using because Blender and Unity use different axes for their FORWARD and UP directions.Īs far as I know, Blender doesn’t have the forward axis defined as either +Y or -Y. blend case later at the end of this tutorial. We will handle the exporting to FBX case first, and then the. I like to keep my source files separate from the production assets so I export to FBX first. As to which exporting method is better and which you should use, it’s up to you for now (we will explore this topic in a future post). In this tutorial, we will cover both cases. blend file in Unity directory and let Unity handle all the hard work. Export models as FBX files and copy them over to Unity.There are two main ways to get your Blender models to appear in Unity:

In this tutorial, we will see how to easily export models to Unity, both static and rigged, in a proper way, which will face the correct forward direction (or any direction you want that you specify in Blender) with all their transforms at perfect values and no unexpected behavior when manipulating their Transform values via code. Unless you have created your own FBX export pipeline by modifying Blender’s FBX exporter and creating custom asset postprocessors in Unity, you failed to find a complete answer on Google, as it was simply not possible to achieve perfect results without putting in elbow grease. Frustrated with the prospect of having to deal with such problems in the future, you come to the conclusion that the second option does not fit your workflow and you turn to option three. This can happen if, for example, different artists who use different export settings contribute to your asset pool, or simply by accident. Your GameObject factory will not be able to tell dynamically how to orient the object correctly, since every object may be exported from Blender with different transform values.

But this is bug-prone and hard to consistently achieve good results with. You could automate this by spawning the model inside an empty GameObject and adjusting its transform accordingly in code.

However, it requires manual object placement into the correct orientation first and wrapping it inside another GameObject. The second option, indeed, fixes the problem seen with the first method, and is a viable solution. You can fix this using the second option. You use Transform.forward vector to move the object in the direction it is facing but your model, instead of strutting forward, suddenly moonwalks backwards, or sideways.

But the joy appears to be short-lived when you try to manipulate the object’s Transform in code. You have your model and you’re enjoying the fruits of your hard labor. The first option works great at first since you don’t have to do anything extra.

Turned to Google to look for the “correct way” to export models to Unity.

Positioned the model correctly in the scene view, slapped it inside an empty GameObject, created a prefab out of it, and called it a day.

So what did you most likely do in those situations? You either:

Objects are either way too big, or way too small, with the Transform Scale values being not uniform (1, 1, 1).

Object Transforms have weird rotation values such as -90 on the X axis, 180 or -180 on the Y or Z axis.

Chances are that the following will feel familiar to you: If you’ve ever had the pleasure of working in Blender-to-Unity pipeline, you will most likely have had weird behaviors in Unity after importing a model from Blender.
