MB-Lab Release for Blender 2.80

Neutronux · May 10, 2019, 7:55pm

UE4 license is incompatible with the AGPL (https://www.unrealengine.com/en-US/eula). All exported meshes from the lab plugin are now bound by the AGPL (that has a stronger copyleft than the GPL). The only exception made in the license (that is still on github) was for models exported by official versions released on www.manuelbastioni.com - The site is off now. I’m not sure about Unity but I think it’s the same (as this would pull their non AGPL source into AGPL).

I know in the past there was an addon to convert an MLAB model to rigify. Does that still work here? And is there any way to get the muscle rig working with Rigify? That would be a very useful feature to have.

DanielEngler · May 19, 2019, 8:49pm

Last time I tested Rigify Meta-Rig for MB-Lab [Addon for an Addon] was still working.

I can take a look into making the muscle rig working with Rigify. (no promises)

Seems there is a new bug in the BVH animation import, I think some changes to the API have happened… been out of the loop for a couple weeks due to other obligations but am updating now.

Just tested it with the latest add-on and it works no problems !

DanielEngler · May 22, 2019, 5:10pm

I found a bug with the rig. “toes_R” is not connected (use_conncet). (is reported on github)

This made me nuts while merging the muscle rig into the rigify rig.

animate1978 · May 23, 2019, 11:50am

Ack!

I will look into this. Oddly the same bone that caused another unrelated bug way back.

DanielEngler · May 23, 2019, 8:33pm

I got the muscle rig working with rigify rig - kind of. There are some issues I could not solve. The knee IK targets are crossed. The feet are rolled in. This makes the feet go unter the ground.

I’m posting here, so more people can see this. For bug reports etc. please post here to not spam this thread with half off-topic posts!

This code is for testing only! Don’t damage your work!

Select the “MBlab_sk_” rig and run this to get the rigify rig:
This takes a long time.

The BVH import bug has been fixed, at least from initial testing after replacing

bpy.context.scene.update()

with

bpy.context.view_layer.update()

This fix has been committed to the ‘master’ branch of MB-Lab

animate1978 · May 27, 2019, 12:44pm

It seems this bug in Blender has been resolved?? I have yet to test this but this SHOULD solve the following issue -

vertices influence broken in 2.80 if using basic muscle armature system

bug

Create a new figure with basic muscle armature system turned on. Finalize it. G…o to modifier tab of the mesh. Switch off the armature's visibility in the viewport and switch it on again. Mesh is totally broken after that action. I used an actual git pull of blender 2.80 from 30.12.2018. If you are not using the muscle system everything works fine. In 2.79 the muscle system works also fine.

Hello users of MB-Lab!

This add-on has come far since we as a community took over the development. We have 230 posts here and already 100+ users on the Discord channel (https://discordapp.com/invite/FuJGcVN)!
Many users have asked on how they can contribute, so I thought it would be nice if we can aggregate everyone’s view and usage of this add-on. With those insights, we can understand this community better and increase motivation ^-^

Therefore, I made a Google forms with brainstorm-like questions, please fill it out!:
Google forms link (click me )

Results will be shared here and on the Discord channel from 2019-06-02 (you can still fill it out later as well). The reason to not share it directly, is that seeing other people’s answers might influence your answers. That can reduce the variety of the answers given, the opposite of what we want to achieve here.

NumesSanguis · June 2, 2019, 3:45am

From the initial post I understand that there should be a collection of clothing that comes with MB-Lab. Is this true? How can I use it?

animate1978 · June 13, 2019, 3:41am

We added clothing in 1.7.1 but had to remove them just to save on the repo size, it grew to a couple hundred MB.

You can find them here though - https://github.com/animate1978/MB-Lab-DemoAssets

And documentation on how to use the clothing in MB-Lab is here - https://mb-lab.readthedocs.io/en/latest/proxy.html

Feel free to ask questions, I can try to answer them as best I can.

Fellow Blenderheads!

The developers of MB-Lab are asking for some help regarding a bug that has persisted since March. It has to do with registering of classes and we are stumped at what is causing this as well as fixing the issue.

The issue pops up when you disable MB-Lab in the Addon Preferences window, you will get an error like this -

Exception in module unregister(): '/home/*user*/.config/blender/2.80/scripts/addons/MB-Lab-master/__init__.py'

At first it was assumed that this was due to the Auto-Updater code that was added around the same time, however upon testing of the removal of this code the bug still persists, so that indicates a problem elsewhere but we don’t know where.

While this only really poses a problem when disabling the addon, in testing and development of MB-Lab this bug has not interfered, it is still very annoying and could be a problem deeper in the code than we know.

We are asking for help, several people are looking at this but we are stumped. If anyone here can help it will be welcomed. I want to get this particular bug squashed for the next release we are working on.

Thank you for your time

Well THAT was fast, for a bug that has persisted for months got squashed in like 6 hours!!

The bug fix has been committed to the master branch so it is HIGHLY ADVISABLE to update your clone.

Character with inverse kinematic , can not use asset library? I download the assets on https://github.com/animate1978/MB-Lab-DemoAssets , and I can open them in asset library if I create character without inverse kinematic , but character with inverse kinematic , the asset can not be seen on asset library

Strange, I was able to do this…

melvi · June 19, 2019, 10:42am

Guys, can’t these models made with manuel bastioni lab be used in game engines like ue4 et.c or for commercial works anymore? I am trying to clarify because if I recall Make Human models are completely free for any use.
