MakeTarget questions

[tomcat]

Decided to try again with Blender 4.3, had a little more luck, but an asymetrical result

I don't get it, you almost got it right this time. You just had to apply a modifier.

MPFB2. On the “Initialize” tab, if click on “Impotr target”, this error occurs:

Code: Select all

Python: Traceback (most recent call last):

FileNotFoundError: [Errno 2] No such file or directory: 'E:\\Forum\\MakeTarget questions\\horn_2.target'

And if select “Create target”, the resulting “.target” files are empty.

I don't know what the problem is.

When using maketarget2 and the command “Copy -x to +x”



the following result is obtained:



In MH, it appears the part that was copied, but not the source part.

and I'm not sure if this is the correct behavior.

There's a bunch of things here. The crash I will have to investigate.

First: when creating a target, the name should be exactly "PrimaryTarget" for a primary target. I know this is impossible to figure out as a user. It stems from historical reasons and bad UX, but using this name is the first suggestion.

Then, to avoid any problems, you should not have any modifier on the base mesh when saving the target. The mask modifier for the helpers might work, but safest bet is to not have that either.

If things still do not work, you could try baking all shape keys before initializing the primary target. This should not be needed, but it will not hurt either.

There's a step-by-step instruction on how to use MakeTarget in MPFB at https://static.makehumancommunity.org/m ... arget.html

Thank you @joepal and @tomcat

I will try using PrimaryTarget as you suggested. I will also have to do a bit of research to parse the 'baking' thing. I'm teaching myself Blender right now with tutorials, haven't covered all the things yet, lol, there is a lot!

Strangely this reply and tomcat's reply do not appear in the main thread. I had to find it by searching for content under your usernames.

Thank you for the suggestions though, which I will pursue

The behavior does not change if left “PrimaryTarget”.

But what is curious is this. If using "Symmetry", the duplicated part will react to the change of the form key value. While the original one will not change. And it is this part that is correctly displayed as a target in MH.

Maybe this is part of the problem?

I notice, in Blender, after I hit Mirror modifier -> Apply and then go to Edit mode, the quads look pretty messed up.

If I just use sculpting tools without the Mirror modifier, the quads look ok

But then the target turns out blank for some reason.

It's not “messed up quads”, the whole modified grid is duplicated and mirrored. Well, that's how this modifier works.

Well, I think it would be 'messed up' from the perspective of MakeHuman, afaict. I'm sorry if you don't like my choice of words.
