Blender 3.4 Breaks Baking Car Steering and Wheel Rotation

[Nick8712]

When using Blender 3.4, baking car steering or wheel rotation does not bake. Attempting to bake causes all keyframes of the rig to be deleted.

im having the same problem, is there any solution ?

Exact same issue here, I've verified downgrading to Blender 3.3.2 the baking works again, but as of Blender 3.4 and 3.4.1 it no longer works.

Experiencing the same thing. The Blender Console reads "Info: Nothing to bake", and any keyframes for the "Follow Path" Constraint get deleted. Baking in 3.3 is a work around.

So good to hear it's not just me. Working on a car animation and steering and wheel rotation aren't baking. I am having the same issue as @jonareno with it deleting my follow path keyframes. Hope it gets updated for 3.4 soon.

Thank you for your report. Yes, the baking operators are broken in Blender 3.4 because they are based on the core bake action operator in Blender. This latter has been slightly modified in 3.4 and is not backward compatible. I will try to make a patch as soon as possible. I have to test thoroughly to be sure the fix will be OK. In the meantime, a workaround that should work in 3.4 before baking:

• make sure you are in pose mode
• ensure that all bone layers are visible in your rig (all the bones of the armature must be displayed)
• then bake the steering and the wheel rotations

How far away is your problem with rig a car 3.4 going to be solved? Both bake windows won't work.

Hi, you can bake your animation in blender 3.3 or 3.2, then save as a different blend file, after that go back to your 3.4 file and append the action, select your car rig, in action editor, choose the action you just imported, then you are good to go.

My entire day was fucked off because of this error

I am also experiencing this issue in Blender 3.6. The F-Curve for the Offset Factor of the Follow Path Constraint is being deleted and neither baking the steering nor the wheel rotation is working.
