LIGHTING AND RENDERING IN VRAY

For the chairs, I used leather material which you can find it in Vray shaders pack *note : All materials must be Vray material.. I used Vray light for diffuse lights.. Since the windows

LIGHTING AND RENDERING IN VRAY

Let's begin with this simple scene I used a box (editable poly), then used extrude command to create the window The scene also had some furniture just to make it not too simple

The materials were added to the floor, white color wall For the chairs, I used leather material which you can find it in Vray shaders pack

*note : All materials must be Vray material It not only make render faster, but also easier to control color bleeding

I used Vray light for diffuse lights Since the windows in this scene are wide open, I used 2 Vray lights at the windows Placing them as you can see in these images below

*note : placing Vraylight inside the room, leave a small space between Vray lights and the wall Trying not to place them intersect the walls because that will make noises for the render

Test Render:

First, you need to assign Vray render for Max Since this is a test render, it is good to keep the image's size small

Going to Render tab, then go to Global Switches , right here you can change some render elements such

as reflection/refraction , glossy effects, etc

Turn off the Default Lights Then click render, you will get this result.

The room needs more lightning and shadows

Let's begin using Global Illumination Turn ON the Indirect Illumination (GI) , choose Irradiance map as primary bounces , and Quasi-Monte Carlo as second bounces See the images below.

Sine this is just a test for lightning , go to Irradiance map, choose Low for current preset and change the sample lookup to Overlapping

For the Quasi-Monte Carlo , leave the defaut settings

Click Render

Click Render

Looking better , but in my opinion it is still too bright This step is up to you, I will decrease the Vray light mutiplier a little bit more (down to 6) Click render

Enough for me Let's begin making more warm feeling by adding the sunlight I used Target Direct light.

Click Render.

Last step is to put some furniture in and set up a high render for final image Go to Irradiance map, choose High for current preset and change HSph Subdivs to 25 (you can put this value higher to get higher quality , but 20-30 is good

enough )
