V-RAY Groom + Texture Xgen Maya (not interactive method)

Realizado en Maya 2018 y Vray Next.
Puntos importantes:
1.- El objeto(malla o superficie) debe tener uvs.
2.- Se utilizan 2 shader, uno para el objeto(el que se vera en el render final) y el otro para la descripcion (para asignar mapa de colores).
3.- El shader del objeto debe ser cualquiera de Maya, en este caso uno lambert. Esto para pintar en el ptex una textura que luego sera reemplazada por la textura que queramos utilizando el "Node Editor".
(No olvidar darle al boton grabar cuando se cambia el mapa. segun muestro en video)
4.-El segundo shader es el vrayHair(o vraymtl) que se aplicara al xgen, es decir, se selecciona "Description" en el outliner y se le asigna.
5.- Al vrayHair se le aplica una utilidad de vray: vrayusercolor y se escribe "color" en el user atribute name.
Saludos.

Important :
1.- The object (mesh or surface) must have uvs.
2.- Two shaders are used, one for the object (the one that will be seen in the final render) and the other for the description (to assign color maps).
3.- The shader of the object must be any of Maya, in this case a lambert. This is for to paint a texture on the ptex that will later be replaced by the texture that we want using the "Node Editor".
(Do not forget to hit the record button when the map is changed. As I show in the video)
4.-The second shader is the vrayHair (or vraymtl) that will be applied to the xgen, that is, "Description" is selected in the outliner and assigned.
5.- A vray utility is applied to vrayHair: vrayusercolor and "color" is written in the user attribute name.

I think You're the only one who explains this for VRay not Arnold and you do it very well. thank you so much for sharing this.

Finally I get the texture,, really I don't know how to think you for best video I have see

[@devilsforkdigital1490]

Useful tutorial, but could have been about 25 percent of the length to cover the essentials. No need to show the Xgen setup (we wouldn't be here if we needed that), or the meandering after you've connected the VrayUserColor node. Good tutorials are concise and to the point, especially without audio to explain what you're doing and why.

I have done it for people who are starting out. Don't worry about details, such as the length of the video. If you review carefully, you will notice that you could have learned something by looking for something else. Greetings!

Thank you! very useful

Every time I link the vray user color data to the vray hair material and assign it to xgen it freezes/crashes. It's got something to do with the Vray user color but I am not sure what; its named the same as the custom shader parameter in xgen. (Im using Maya 2020) Any thoughts?

[@3djdavid]

I will check it. What version of vray do you have?

@@3djdavid thanks for the reply, I'll just use arnold instead. Can't get the crashing issue to stop.

[@raularosemena]

hello! for some reason this is not working for me. Any idea? Hair keeps rendering white, no texture.

[@raularosemena]

Solved! plugin xgenVRay.py needs to be loaded! check auto load too
