Hello peoble!

i am a very new newbie at vray so, I have to know this:

I wonder if I can save some kind of map or IM so the it renders fast..you know like when you save a photon map in mental ray?

otherwise i have to wait for prepass 1 and 2 and then render.


Thanx for help

sure it can :)

VRay Manual ONLINE:

http://www.spot3d.com/vray/help/150R1/render_params_advancedimap.htm

for the calculation simply check:

- "Donīt render final image" in the global switches

- depending on what youīre animating set the "Every Nth Frame" to something between 5-15

- set the irridiance map mode to "incremental add to current map" and save it to a file

- set "on render end" to autosave

thatīs basicly all...youīll get a worning that you are up to render a sequence without saving a file output but thatīs okay. you donīt wanna have jpegs or something...you only want to save the irri-map :)

kind regards

raytrace materials together with VRay is kinda NoGo :(

use a vray material with a bright reflection color. maybe use the EGZ materials: http://www.vray.info/materialbeta.asp they include a carpaint shader...

have a look at VRay-Materials.de as well: http://www.vray-materials.de/all_materials.php

there you gonna find tire rubber as well e.g.

read the VRay manual i posted above: http://www.spot3d.com/vray/help/150R1/ if you wanna use VRay for future productions that should be your bible as well as: http://www.vrayelite.com/

there are tons of tutorials around concerning carpaint and vray in particular.


kind regards

I did exactly like you said but it didnt work ..( by the way im doin moving object animation.)

- the prepassing 1 and 2 is still coming
- it renders the same frame whole the time (for 83 frames) thoug I animated the object and set range from 0 to 83?

thank you for help
