Vray Occlusion Pass

The only problem with the global soultion is if you have various bumps applied to different objects. You would have to create separate vraydirt materials for each. It would be a pain if you have hundreds without a scripted solution.

Is that what you've been wanting to do?

no sir..
how bout my bump maps..

i mean just overide all materials using 1 difuuse maps and self illumin & there bump maps stay
i thnk brazil render can do this im not sure.
is this possible in vray?
here 2 illustrate

1st image, im using AO vraylight w/ vraydirt on textmap no bump chanel
2nd image, like what u told me, standard mat vray dirt on diffuse en selfillumin with bump maps..
see the difference


i like this effect

now we go back to my last thread
do u have any suggestions? more convenient way how to do this easily..aside from my method??

thanks vertex

BTW, we're working on a plugin solution to automatically nest your diffuse maps with vray dirt to fake indirect lighting as a quick alternative to GI.

I'll release it for free to the community when its done, tested and ready!

Actually you can do that too by just putting your bitmap on the UNOCCLUDED MAP inside vraydirt.... It's what I do on my wood texture mapping... result is far more better wood looking than an ordinary wood shader. BTW it also goes well with rock maps with bump or displacement! It simply.... ROCKS!!!
