Maybe try with Blender 2.93.
Blender 3.0 released yesterday introduced Cycles X which may be the issue.

Loving the Mecaface rig so far, great job with this. In the tutorial you mention being able to do facial motion cap with the rig. Do you have any info to share on how to accomplish this? Or is there a video out there with this info? I was not able to find anything.

does it work with epicfigrig?

yes. it works with anything.

Resetting the pose with alt-g, alt-r, alt-s is a bit weird in that the eyes disappear and the mouth opens pretty wide.

You arnt supposed to reset the pose with your alt g alt r nor alt s, there is a 'base' pose in the pose library which you should use for resetting the pose.

Hello. Are we going to get an update for 3.0? or has it become to hard to make? I'm just wondering because an easier to use version would be great and also as blender progress's this addon becomes less and less compatible. For example, I don't know if this is a compatibility issue or not but after applying the face rig to my first character and then clicking the "Finish" button to apply it, when I go to add a new face rig to my other character it just takes off the face rig from my previous character and re-applies it to my other character? is this a bug or an incompatibility issue? I am using blender 3.0.

Thanks in advance for the help!

Hi. There is no need for a new MecaFace update for blender 3.0, as every feature works the same as before. However a new version is planned to be made soon but I don't know when I'll get to that. But the issue you brought up doesn't seem to be a thing to anyone else. So make sure that you selected the armature and clicked the appropriate 'finish' button. Make sure you don't somehow click the one under the lines category. Also make sure that it did work and renamed that armature to 'DeFin' or something along the lines of that. Finally, make sure you don't have another MecaFace in the scene that you didn't do it to. Or else that will cause problems.
So about that new version that I will work on soon, I will completely remove that 'finish' feature and all the 'apply colour' features and make it work properly as I'm more experienced now. Please be patient as I have many other things under my belt atm so don't expect it too soon.

Hello, thanks for the response. I figured out it was my fault because I was clicking on apply "eyes" instead of finish "Final" also I apologize if I came off as impatient for the new version. I understand the amount of hard work that goes into development. Thanks for the response!

Hi, can animations created with this plugin be used for commercial purposes? Thanks!

Hi. Following the mecabricks license, you can not use it for commercial purposes. But you can use it for YouTube videos that are monetized.

Is it limited to YouTube? Can other websites that can profit from advertising also? thank you.

@GuaiYong If you use Mecabricks assets within your videos, commercial use is not allowed without a specific agreement. It includes commission work, monetized videos etc. However for non commissioned videos which are publicly available, monetization is currently "tolerated" provided that Mecabricks is credited.

Can we do Face Motion capture with mecaface?
It is lot more easy

yes but i do not recommend it. Lego faces are stylized and do not mix well with motion capture.

true it may overlap

but can u tell me how to do it?

I did not mean by saying it wont mix well that it may overlap, im saying that it would look bad. but figuring out how to do it is something you yourself need to figure out. the one time i did it i set constraints to the bones parent them to empties from the face tracking i did. Thats all i can remember.

Thank you

I don't understand how the licensing works. Anything created with this plug-in (or the MecaFig plug-in) should not have any licensing attached. These are creative tools that were purchased. It's like buying Photoshop and then asking Adobe if you can commercially publish the images you created. The only licensing that should be strictly enforced is any kind of redistribution or sale of the plug-in itself. Anything you create with these plug-ins should be free of any license. That's what GuaiYong was asking, not about Mecabrick assets. Please correct me if I'm wrong.

I would also like to mention that MecaFace is a great tool, but it has many issues. It is essentially an unfinished product that we've paid for. If it was free, you would be free to either support it or not. But I don't think it's fair to charge for it and then say that you have many other things under your belt and we should be patient for an update. It's been more than 2 years since your last update. Your customers should be a primary concern, or else don't charge for it imo.
