Xgen interactive groom reference issues

Hi there

 

I have a char that I am referencing in a bunch of scenes:

 

t2.jpg

 

If I save my file with this char referenced in a pose other the the neutral, when I open it again this happens:

 

t1.jpg

 It looks like as if the hair is being affected by some kind of gravity.

If it is saved in the default pose, everything works, including the batch render animation.

I have no idea whats going on.

 

Any ideas? Thanks a lot!

Hi @brurpo

 

Out of curiosity, if you delete the Xgen hair and reference and save the character in a different position does the same issue occur?

 

I'd like to narrow this down to an issue either with the hair or the rig itself not being referenced properly.

 

Please let me know if anything changes!

Hi there! 

 

Thanks for the reply!

 

There is no issue with the char or the rig. We are already using it without the hair in our pipeline.

 

The problem is with xgen, if the scene is saved with the character in a pose other than the one in the reference the hair bugs and is all messed up when reopening the scene or doing a batch render.

 

This does not happen if I import the character instead of referencing it (but this is not an option for us, as we already have the char animated with lots of constrains and just need to replace it with the one with hair).

 

The solution that I am using right now is keying the char in the T pose, with every controller zeroed out, at frame 0, so its just like in the reference file and save the file there. (this give us motion blur problems so its not a perfect solution)

 

It seems like an odd bug with xgen, or I am doing something really stupid, I dont know.

P.S.: I am not using namespaces

@sean.heasley You can reproduce the error yourself, following these steps.

 

1- create a sphere

2- create an interactive groom

3- do some simple grooming

4- save the file

 

5- create a new file

6- reference the groom sphere file

7- rotate the sphere 45 degrees

8- save the file

9- reopen the file and the hair is messed up

ADITIONAL STEPS

 

10- Rotate the sphere back to 0 degrees

11- save the file

12- reopen the file and the hair is normal again

Hi @brurpo

 

Thanks a ton for the repro steps!

 

This does look like an issue with Xgen so I went ahead and logged this with our dev team so they can work on a fix!

Yeah, no, guess 5 years is not enough time to fix a critical issue.

That happens in multiple fronts, thats why we are phasing out autodesk for other solutions wherever we can

I will start singing happy birthday every year this issue continues without a fix.
Almost 6 years, nice.
