3ds Max CAT Bug List

#1

For the Leg limb bone chain, changing IK/FK rotates the ankle.

Play Video

IK/FK doesn't have the same pose even if you use 'Move IKTarget to Palm' or 'Match IK and FK' buttons. Workaround for this is using helpers and align.

#2

Saving and loading a clip from a rig that has different amount of bones in a leg, doesn't work

Play Video

If you save an animation from a character with 3 bones in a leg (Leg1, Leg2, Leg3 and Ankle) and load it on a character with 2 bones in a leg (Leg1, Leg2 and Ankle), it breaks. I think this wasn't the case in older versions of 3ds Max - 90% sure it worked fine in 3ds Max 2014. Not sure about others.

#3

Pelvis bone is gimbal locked by default

(The problem is that by theoretically fixing this, it could break a backwards compatibility with older rigs. Rigs and animations before the fix would be different than after the fix).

#4

Displaying Motion Path for foot IK platforms (maybe arm IK platforms as well) doesn't display the path if Motion Layer is selected

Play Video

Displaying Motion Path for foot IK platforms (maybe arm IK platforms as well) doesn't display the path if Motion Layer is selected. You have to click on another layer to display it.

#5

Displaying Motion Paths for the whole leg when IK platform is selected as well, bugs out the digits (fingers) in the leg

Play Video

Displaying Motion Paths for the whole leg when IK platform is selected as well, bugs out the digits (fingers) in the leg. By changing the panels, it update the viewport and fixes it. But is still buggy.

#6

When using CATMotion Editor the window doesn't update properly

Play Video

When you use 'Undo' after you changed the curve in CATMotion Editor, the window doesn't update unless you click on any other parameter and then back. The same thing when you scale the keys outside of the current zoom. It should expand so keys are still visible.

#7

After collapsing the layer stack, Tail bone chain displays black keys on the timeline also in every other layer

Play Video

After collapsing the layer stack, Tail bone chain displays black keys on the timeline also in every other layer. Even when no layer is selected. Deleting these keys manually solves the issue.

#8

Layer stack with animations with a lot of keys in them (collapsed layers for example), take extremely long time to save

Play Video

Layer stack with animations with a lot of keys in them (collapsed layers for example), take extremely long time to save. This wasn't the case in older versions of 3ds Max.

#9

After you load a clip, animation in viewport looks broken, until you move the timeline

#10

Digit Manager doesn't work properly if in Setup Mode, you move the first bones of fingers in relations to rest of the finger bones

Play Video

Digit Manager doesn't work properly if in Setup Mode, you move the first bones of fingers in relations to rest of the finger bones.

#11

When using Animation->CAT->Capture Animation, the Tail bone chain is not present in the list for CATRig Mapping

#12

Transform Gizmo offset doesn't load until you move/rotate it again

Play Video

When you offset Transform Gizmo in a layer and save/load that layer, it will load without the offset until you move/rotate the gizmo again.

#13

Saving Animation/Pose via viewport for digits gives MAXScript error
