Lighting and Rendering in 3ds max using Mental Ray

by Nabil Chequieq

Hello, I am Nabil Chequieq and welcome to my tutorial, you will learn how to light and set up some materials for a nice result in a shorter time.

To start make sure you are working in a metric unit with realistic proportion, first I used a Daylight System






Let's change the setting of the sunlight and skylight to MR sun and MR sky and for fast calculation of Global illumination and activate the  mr sun photons.

Now let's take a look at some materials actually I prefer to render some objects with ambient occlusion in max before occlusion pass for that's arc and design material have an option called  special effects we can activate the ambient occlusion








For the wall I used a little bit of noise in Bump map.

and for the glass I used a different kind of material called ProMaterials with a persona setting.



Now let's take a look in exposure control ( 8 ) keyboard short key, default when you choose Daylight, max tell you if you want to activate it, these are the settings...

For the indirect illumination I used final gather and little bit of global illumination, I don't used the diffuse bounces.

and I used some passes in render element for compositing in Photoshop and this is the cool stuff.

and this is the render



now the setting of the ambient occlusion.


in Photoshop I am doing some colour correction and contrast.



and this is the final render.



 I hope that you have learned something from this brief tutorial and if you have any questions then please feel free to contact me. Thanks
