Quick and easy GI Setup

#1

I recorded a video showing how to create a quick GI lighting setup using Mental Ray, Final Gather and vertex painting. Hope you find it useful.

Edit: Just hitted a snag, i cant applay the “Glow-lume-with-vertex” material to my sphere.

That’s strange. Can you apply other materials to the Sphere?

This is how i did. 

1. Pressed on a empty slot in the material Editor
2. Pressed the button "Get Material"
3. Choosed Glow(lume)   (the one with a yellow square infront of it)
4. Pressed on the Glow button and choosed Vertex Color, and set the map channel to 3.

But the problem is, if i start with a material with a yellow or a green square infront of it, i cant apply it.

EDIT: Ah! now i feel pretty stupid! Forgot to choose Mental Ray as standard in the Material Editor! It works fine now! Thanks again for the tutorial!

EDIT2: Wow, that was fast! It tooked me about 5-10 minutes to render this scene! (Have a laptop 1.6 centrino and 512ram)
Used 16min and 64max on Samples per pixel and 5000 samples under Final Gather.

Very nice method! Wish I’d found this a week ago!:smiley:

#8

Mmmm, teapots. Looks good. I’m glad you guys found it useful.

#9

Ouch, bandwidth got killed. How fast did i go and how big is the file? I may be able to mirror.

#10

man i can;t download the file!!

bandwidht exceeded!!

#11

The link isn’t working…

#12

It’s about 44 megs. I was hoping the limit would hold out until the end of the month. I guess 20 gigs doesn’t go as far as it used to. :slight_smile:

If you’d like to mirror it, that would be cool. Or if anyone wants me to send it to them, that’s fine too.

#13

Looks like fun… I’m very tempted to start giving MR a try.

#14

The link should be working again. Feel free to let me know if anyone has any troubles.

#15

thanks…it;s working properly now!! i m downloading it now!!

#16

Brilliant idea Jay… thnx for sharing it with us champ :wink:

#17

Excellent tutorial, good job! Will definitely be usefull in future projects for me :slight_smile: Thanks a bunch!

#18

Still downloading the tutorial, but I wanted to say that I am having a bit of a time getting some nice volumetric lighting from ‘outside’ to shine in a window and also use caustics on a glass. It should be interesting to see.

I just watched the video and great tutorial! I can see how this would be a really quick way to get a nice preset library. Thanks for the vid. :slight_smile:
