Final Render Satge1 Sunlight Tutorial
by put3d on เม.ย..10, 2009, under 3ds Max Tutorials, Final Render Tutorials, Tutorial
In this tutorial we will learn how to use Final Render to render sunlighted room.
The scene is very simple: room with random scattered objects and pre-assigned materials. There is windows passing the sunlight.
Firstly, we will analyze the effect of sun light at the day times:
There is direct light cast by the sun directly through the window, this light will illuminate the area under the window and will cast dark and hard shadows on the ground.
There are also indirect lighting caused by the reflected rays from the ground and the walls. This type of lighting will illuminate the entire room with fading out at the far areas of room because the several bounces of light from the walls and other objects will weaken the light energy. The shadows from this indirect lighting will be very soft and faint.
Also the sky dome and clouds will cast rays. This is generally is the most important factor of lighting at the day time because not all area will receive direct sunlight but it will recieve some kind of the sky dome light. The sky is the biggest visible object in our world so it is the most important factor at day times. And will be effected by the weather if it is cloudy,windy or so on. The shadows cast by this type are soft and less dark
To simulate these 3 types of lights we will use 3ds MAX direct light to simulate the direct lights from the sun, for the indirect sunlight we will use final Render rectangle light and environment map (HDRI and so on) for the sky dome light.

I’ve read through a number of posts on your blog now and just want to mention that I really enjoy the way you find a way to phrase and also explain everything, it makes it very easy to read through. I also totally agree with everything you have stated here, these kind of things are very important to the planet and the earlier we all realize it the better we will be off in general.
