Exporting interactive XGEN description which the guide are made from CURVES

[cocachaumont]

hello there, 

I have a question about the interactive XGEN, I had created all my guides on my first descriptions by hand and to make the second layers of hair (like flyover) of these descriptions instead of redoing the guides from 0 I thought I could export my existing guides in CURVE to re-import them as a guide on a new description, no worries about that, but in the EXPORT area it gets stuck, if I delete my curves from my scene my description guides of flyover are reset and so if I export my description in a new scene then the curves are not there so my groom loses his shape,

how do I "compile" or rather tell Maya that my guides don't need the curves anymore

the first screen is my groom in the grooming scene and the second is when i import the description on a new scene

thanks 😞

I find the solution, i was importing my curves in my curve to spline modifier as curve and not cache so the cache worked fine. But now I have a batch render issue, only one description (with cached guides) changes his behaviour during batch render, render sequence and renderview is working fine thought. (on the screenshot, batch render left, render sequence right)

Hi there, I already posted a reply with my solution : "I find the solution, i was importing my curves in my curve to spline modifier as curve and not cache so the cache worked fine."  but it was still a trouble for batch rendering. I've found some tricks to counter this issue but beware it's still not 100% the best thing.

I'll write a lot but maybe it'll help someone in need for another issue!

First I tried to render only the hair in the scene (I delete the most heavy stuff in the scene, not everything for keeping a credible lighting ) it worked nice but sometimes at the few last frames it crashed. So I had to re-render everything because some hair changed their positions. :')

My advice is to not make Xgen hair with cached guides as a base. The solution I posted work with guide made from scratch.

At the end in my movie, I decided to buy Groombear (houdini plugin acting like Xgen in houdini! More stable!) And I exported all my hair, guide in houdini and made alembic export, importing them in .ass format in maya, it was more easy to render, more fast (instead of 1hours/frame, I had only 2min with the exported .ass) but the only inconveniant I found is a difference of shadows between the hairs I had to tweak things and uncheck things in the StandIn overrides.

hope this help!
