Hi there! At around 10:50 my motion clip sequence has an error: “VEX error, 16/58 of the joints in the second clip are not present in the rest frame of the first clip and have been deleted”. When I plug that into the motion clip evaluate and bone deform, the rig goes from the T-Pose to just the hips. The same thing happens with the project file. I checked the individual clips (tpose and walking in place) and they both work on their own. Is there a way around this? Thank you!
Hey Matthew, this is most likely an issue with the Mixamo FBX you downloaded. Mixamo characters seem to have a ton of issues with either a mismatch in attributes or number of bones in the animated and static rig, which KineFX does not like. I added a download link below to an updated version of the same scenefiles with common fixes for those mixamo problems and a version that uses one of Houdinis default animated characters. You can also take a look at the comment sections on Patreon of episodes 9, 11, 15 and 29 (basically every episode with a Mixamo character) to find other approaches as well. https://entagma.com/downloads/Kinefx/KFX15%20Fix.zip
I mentioned another possible fix on vid 9 and it worked for me again here: a wrangle with i@scaleinheritance = 0 for anything coming out of the animated output of the Mixamo character.
It fixed the transforms when getting odd discrepancies in size on motion clips.
Hey! Chris chiming in here: This episode uses FBX Files, which sometimes can cause issues with KineFX. We’ve adressed these issues and all our known solutions in Episode 31 of this course. If something in your setup isn’t behaving as shown in the video and the error persists if you load the scenefile, give Ep31 a watch!
