Vray Distributed Rendering from A to Z

[hellraiser]

Intro
First of all, sorry for my english – doing my best. Second thing, I’m not claiming that I’m professional in all related to IT and network configuration so feel free to comment anything that you will see wrong. What I’m doing here – presenting my Vray DR workflow that is working for me and should work for others. We will not talk about secure local networks or such things, only thing we are interested in is wokring distributed renderer.

So let’s get started!

Muchas gracias por tutorial! Lo que me ha surgido un problema….

Al renderizar por render distribuido, los buckets del nodo me salen sin texturas. Agradecría si me pudieras ayudar a solventar este problema.
Muchas gracias.

from hellraizer:

first of all he needs to double check if all materials textures have propper file path like //pcname/textures/ for example
he can check paths by pressing shift + t
if im remember correctly 🙂
second thing
posiible that some node has no access to project directory
and node cant read textures
if just some nodes dont render textures then problem is in second step obviously
double check permissions on those nodes
its critical to have read write access for all nodes on current project folder

Obi3D:

Lo primero que nada el Vray 3.20.02 tiene la gran ventaja de que transfiere todos los assets (texturas, y otros archivos que son leídos en base a una librearía). Estos los envía a través del spawner a un temporal, junto con la escena, a las distintas maquinas (nodos). Para eso todos los assets tienen que estar leídos desde su origen. Para esto necesitas que todos los Path, o direcciones en la lista interna de 3d max, estén agregadas.

Luego de esto necesitas hacer una lectura forzada en todos los assets (ir a asset traking y generar un strip path) con esto podrás ver que path están siendo ledos y cuales nos (lo que no dirán missing y los que están leídos diran OK)

Una vez hecho esto tienes que generar la lectura de la dirección (make path absolute). Con esto todos los path estarán leídos y podrán ser distribuidos.

Todo lo anterior se aplica como regla general.

Tienes dos opciones para que los nodos puedan leer correctamente cada asset:

Por medio de transferencia gestionada por vray (rollout> general_DR setting> transfer missing assets
O por lectura directa de cada nodo a una carpeta compartida o copiada que contenga exactamente la misma direccion donde estan los assets.

LAS PUTAS

Muchas gracias! voy a probar y os comento! Saludos

Sorry amigos, I don’t understand spanish 😉
Here is some tips to check if your nodes have correct permissions on working folder, so that you don’t have any texture problems in future.

1. Fix all paths in 3DS Max scene
Open asset manager (press Shift + T ) and check all paths there.

Path marked with green is OK for DR but red path render nodes don’t see at all so if you have some textures with such path – FIX it!
2. Check read write permissions from all nodes
You can use software like teamviewer to access nodes from main workstation. So lets see one example how to check permissions. Go to one of your nodes and open Run dialog then write path to project folder where textures are located in my case it’s something like Start – Run ” //alphapc/projects/exampleproject/ ”
Then go in sceneasets/images folder and try to copy some file there from render node, and then delete it. If you can’t then it’s obviously that you have no permissions to access this folder from render node and that’s why it can’t see textures and some buckets in render are without textures.

Fix shared project folder’s permissions .

If you need more explanation on this just ask here or Eric via skype and ill try to explain more.

Hope this helps!

Yes missing assets transfer also helps, I just like to work clean and set up all paths correctly all the way from beginning 😉
There is only one disatvantage for asset transfer, sometimes i’m having very huge scene with very large textures and imagine that all this stuff is transfered over network to some amount of nodes. In my case i have small HDD on nodes and that is problem for me.
