Some experience with Blender is recommended.Check out some of the beginner tutorials on the website. You have a minimal understanding of the Unity editor.The latest stable 64-bit version of Blender is installed on your machine.You’ve downloaded and installed the latest 2020.3 LTS release of Unity.Enhance the character with accessories and objectsīefore you begin, verify you meet the following requirements:.Create an armature (skeleton) for a character and rig it.In this tutorial, you’ll learn how to prepare a humanoid model using Blender and how to bring it into Unity. It allows for easy set up of animations, the blending between them and retargeting of humanoid animations between models.īeing able to reuse animations allows you to use animations from the asset store and websites like for your own custom characters. This allows you to use the same animations for characters of all shapes and sizes. Nowadays, most game engines come with a system to allow reusing animations as long as the skeletal hierarchy is compatible. As an amusing example, the older FIFA games had players all be the same size because creating a separate skeleton - and a set of animations - would have been a nightmare. This limited character diversity as their height and proportions had to be the same as well. In the past, characters needed to have the exact same skeleton to share animations. Imported rotations in Unity (truncated for readibility):Update note: Eric Van de Kerckhove updated this tutorial for Blender 3.0 and Unity 2020.3 LTS.Īrtists create 3D characters for your favorite games with the use of models, textures and animations. Likely to be an euler issue, if only Fbx used quaternions.Įxported rotations from Blender, using a "print" command in the Fbx script (truncated for readibility):
However it's the way these values are read in other app that is the problem.
Seems to happen when a bone is making 180 degrees x-axis angle with its parent.Īfter further investigations with the Fbx exporter code, tracking the exported rotations values seems to output correct values. However it's not a clean solution, it may happen in other situations. Rotating in Edit Mode bone2 1 or 2 degrees in Blender fixes the issue. When exporting to Fbx and importing in other apps, such as Unity, "bone2" is imported with Rot X = 179.8, instead of -90. It now only contains one mesh and two bones.
While praying for this bug not to be forgotten in the dark, i've simplified at maximum the example blend file (attached) to help.
