I would work with cm units but the problem is that I have to use Welcome to the Autodesk Maya Subreddit. If your Maya units are M XGen will still calculate density in CM so a density of 10 on a 1m square plane will produce 100,000 hairs. The two guides towards to the left side of this picture is the the guides mirrored. Also I believe the mask map size is separate from your uv map resolution. Only then will the splines regenerate accordingly to the groom splines (which are only for the viewport). com/joeparente34/Follow me on arts Some tutorials in Youtube recommend to create the Density Mask in Zbrush.

But even if I max Daryl also walks through some tips on using and painting masks, which can be critical for managing high density scenes. I created a groom in the regular xGen and then recreated it in XGen Interactive. Whenever I export a dense groom from xgen as alembic curves, the result always reimports as multiple groups, this causes a lot of issues on import and recombining them manually is very processing and time intensive due to the density, is there a way to The xGen ensembles improved upon electron density fit compared with the PDB reference coordinates without making use of atom-specific B-factors. That said making something this complex requires a lottt of coding, algorithms etc. I've read that that's a scaling issue, but my model is not that small, and everytime I change the scale nothing changes. Select the guides then open the attribute spreadsheet. On several other projects, this would happen when trying to paint maps on a mesh on which I'd worked and had some history. Maya subdivides the faces into a density grid, and stores a density values in each cell. cover I solved the problem that I had regarding the fact that the hair could not be seen in xgen, or it seemed that it did not generate it, you just have to deactivate the button "use default material" which is in the viewport bar We would like to show you a description here but the site won’t allow us. facebook.

Note: You should be using a density map or expression in your procedural clumping. 00001 (otherwise it creates too much primitives). “Density” controls the amount of hair created for the groom, meaning a low amount equals less On this series you are going to learn the basics of xgen grooming completely free. I have a set of curves that I want to use as guides for the hair generation, but whenever I set XGen to either use the curves as guides or convert the curves to splines I have no way to up the density on them. Also in the middle of my head there is sorta unpaintable strip. It Hi, I have a problem I created hair with XGen with guides and created hair system.

Sadly I don't think there's a fix for undoing this to get the proper Density value back. The problem is, when I turn the splines to guides and look at the hair, it really isn't following the guides very closely at all. A solution will be to follow the method above and then export the scalp to Zbrush, paint it and re-export it as mentioned in the link below: Creating Realistic Hair with Maya XGen by Hadi Karimi Duplicate the object and assign Lambert or whatever is default material, xgen region maps doesn't work with Arnold materials.
