In this tutorial I will go through a simple, yet effective way to setup a lighting rig using 3ds max and vray. Before we begin we need to setup the.

This light is 'indirect' light, calculated by global illumination.
So we need to enable GI for it to cast any light. More info on GI can be found here. Adjust the settings like in the screenshot. As you can see, we use a multiplier of 0.
If you never use too bright materials see previous step and use these GI multiplier setting, you will never get problems with your GI calculations. Using pure white materials and full GI multipliers can confuse V-ray, so this is a simple trick but it does make a difference!
Now if we render again, you will see the teapots. The skylight is an environment light, which means it casts light uniformly from all directions. This results in very soft shadowing and uniform lighting on all surfaces. Adjusting the skylight In the environment rollout, change the multiplier next to the skylight color to 1.
The scene brightens up, because the multiplier is used a the skylights 'strength' value. Also try some different skylight colors to see the effect on the rendering.
Add a 'sun' To make the lighting a bit more interesting, we will add a direct light to the scene. I used a directional light with vrayshadows turned on.
Make sure the light is bigger than your scene check screenshot to see the light settings and placement I used. When you render, the scene is way to bright because now we have a skylight of 1. And this is the position of the Vray Sun:. I increased the value, because I wanted to have softer shadows, by increasing the size your shadows will be more blurred but the intensity remains the same. The tittle maybe confuses you, but yes it is correct, what I mean is that for exterior rendering you need a different lighting for the inside, if you are rendering a exterior daylight scene you need a soft interior lighting just to show a little bit of the interior, so you do not steal the focus of the exterior.
Also it is important to know that you have a bright interior, the exterior have to be overexposed and that will kill your image. For that reason you only see a little bit of lighting in the renderings, just to show that they are people living in that house!
Vray IES gives you a real life feeling, because they use real life lighting data. The settings for this lighting are the next:. As you can see the color is based on kelvin temperature, this gives me more control, and I am using a warm tone, so the house will look more welcoming!
I really love the vray physical camera, because it feels like a real DSLR camera, where you have access to change the aperture, lens, shutter speed, ISO, etc. This gives you total control in how the light affects your 3d render, in this case I did not make a lot of changes to the camera, and here you can see what I did:.
As you can see, I changed the focal lens and increase the f-number to 9 because I wanted to catch less light and avoid overexposed surfaces, for the white balance I am using a blueish tint to compensate the sky color.
I did not change the shutter speed or film speed ISO.
The grass is a important part of making your exterior more realistic, there are plenty of options to create a beautiful and realistic grass. In this case I am using forest pack for the grass creation, the first thing that you need to make is several grass patch so you can distribute them around your surface.
As you can see, it is a very simple model of a grass with different size, shape and distribution, them I use 3 of them for the grass field. Now you need to select forestpack from the menu, click in your surface and add the different grass patches to it. If you see that you need more grass you can decrease the scale so it cover more space or decrease the units, that would add more grass to the field.
As you can see I have all my grass converted into proxies, I did that to avoid losing the settings because sometime forestpack does not visualize the grass, what I do is to save a file with settings and them create another one with the patches converted intro proxies, the only bad things about that is that you can not change any settings when you do that, for that reason I save a backup file. You can do that if you are going to send the file to another person so you do not have any issues with the rendering.
The renders settings play a big part of getting a realistic render, if you do not make the right changes in your settings it is probably that you will get a wrong result, also it is important to understand how vray works in order to optimize your rendering process.
Post production allows you to make a better version of your raw vray render, so you have more tools to tweak your image and make it more realistic. In this case I used Photoshop to enhance the render, use tools like Highlight, Black, Contrast, Clarity and Sharpen, I was able to improve the final image. Creating beautiful and realistic images required time and effort, and you need to be patience and always try to learn how you can make your render to look better.
Remember to practice and try to emulate real photograph, doing that you will have a real feedback on how the things looks in the real world. Study some lighting, go outside and take some picture, that will help you to understand more about lighting and how to setup the vray camera in a proper way. In this Corona Renderer 3D tutorial shows examples of Common beginner user mistakes and how The most common use of these is for creating spotlights with a natural falloff.
The lights are angled upwards and give nice shadowy detail to the boundary wall. These are great for lighting outside vegetation as a decorative effect.
Add some Contrast and Levels adjustment too for making the image appealing. This helps in getting an idea of what pops out in the scene. You can get creative by painting some white glow over the windows and blending them softly with the scene.
This can make the windows themselves look a bit washed out.
By using the burn tool over the windows, I can now retrieve the contrast to that area again. Similarly you can use the dodge tool to lighten certain areas that may be too dark. Hope you found this tutorial on Exterior lighting and rendering helpful.
