Welcome to the Blockbench 4.1 beta!

This is an early version of the upcoming 4.1 update, which introduces a lot of new features, including Inverse Kinematics and Collada Export!

You can find the latest version of the beta here: https://github.com/JannisX11/blockbench/releases

To test this beta, download the required installation files from below, or enable the setting "Update to Pre-releases" inside Blockbench. Enabling this setting will tell Blockbench to always update to the latest pre-release, allowing you to test the latest features. Please note that pre-release versions may be unstable and have more issues than release versions.
Automatically updating Pre-releases does not work on Mac at the moment.

Please report issues you find in the beta, make sure to specify the correct version.

Changes

Inverse Kinematics

Inverse Kinematics are back! They allow you to animate a chain of bones by moving the end point. Here's how to use them:

• Set up a bone chain, this can be a leg, tail, etc. Make sure all pivots are correct
• Add a Null Object (from the edit menu) to the parent bone of the chain, e. g. the bone you do not want to move
• Right click the Null Object and select the IK target. This can be the bone at the end of the chain, or a locator at the end of the chain.
• Switch to animation mode, create an animation, and animate the position of the Null Object. This will animate the bone chain to always try to reach the target.
• Export as glTF or bedrock animation. Make sure to also save the project as a .bbmodel file in order to keep the original movement of the null object.
• Note that the option "Lock IK Target Rotation" is not implemented at the moment
