New Training - Physically Accurate Lighting in mental ray

We go from an unshaded room to a fully lit and shaded scene in less than 3 hours. All scene files and textures are included with this project, an introduction video and larger renders can be found [here].

Many thanks to David Mitchell from Alter Studios for the original concept, and bullet I hope you'll enjoy this one. It was made with you in mind now that you have all that free time on your hands user added image

This looks really appealing, but what light types are covered. Is it has more than just the physical sun & sky...? Could you please post a list of what each lesson covers, because if it covers various mental ray lights and mia_exposure photographic I am sold user added image

No, it doesn't just cover physical sun & sky the aim of this tutorial is basically to get you to understand the physics behind indirect lighting in mental ray through example. It's pretty technical and a good reference point to come back to, the main aim is to get you to understand how things work rather than pushing buttons.

For lighting it explains FG maps and their limitations, portal lights, GI, and how to use these things in combination to speed up renders. For shading & texturing it covers gamma correction nodes, sss shading and mia_material_x. We've used the simple exposure node because nothing in this scene requires the photographic one.

The first two parts cover theory and the next six lighting of the interior scene.

Part 1: Linear Workflow & Lighting to Scale
Part 2: Physical Sun & Sky Nodes
Part 3: Color Bleed & FG Maps
Part 4: Portal Lights & GI
Part 5: Stained Glass with SSS Material & Light Throw Pattern
Part 6: Frosted Glass, Gloss Paint & Wood Floor
Part 7: Adding Background & Finalizing Shading
Part 8: Bringing in Tree Shadows & Final Tweaks
(Addendum: SSS Material for older versions of Maya)

You're welcome, will be very happy to see that bedroom come out stunning in the near future I like the model.

Haha for the record I mentioned bullet specifically because he loves the original scene, it was done in LightWave a few years back and he always wanted to do something like it in Maya.

Thanks Miss_Nova for sharing that info, sounds like it is just what I have been looking for!
Once purchased, is it possible to download whenever or am i limited to download only within a time period?
I only ask as my 'broadband' at home is worse then the 3G on my phone so It might take some time to complete the download!

Three times not bad haha I spent a few months on a tiny island last year and you'd be lucky to keep the internet for 5 minutes.

Good luck with the tutorial and thanks for supporting SimplyMaya.

no its not done in PS. it is simple render in maya software. i have used two spot lights. one for main white beam and another for colorful dispersion. I don't know much if it could be rendered directly depending upon the reflection of rays in prism.
this method might not be technically right but this prism dispersion effect can be achieved with this simple method. to create that multicolor dispersion effect all you need to take a spot light and apply light fog and then in fog intensity apply procedural noise or fractal map.
this way u will get rays in fog and to make it colorful simply apply 7 colored gradient in the light color later on you can increase the size of dispersion effect by using regions of fog. i hope this will solve your problem.

Just did a search on that guy's response (if indeed it is a person), and it was said by another member ages back in a different thread... No idea why anyone would do such things...
