lighting was created for the 3D interior scene modeled beforehand. 3D Studio Max was chosen as a modeling software because of the earlier knowledge and the yazik.info -visualisation/. yazik.info 3DS Max is a professional 3D animation rendering and modeling software package used mostly by game developers, design visualization specialists, and. 3D Lighting: History, Concepts, and Techniques .. THREE-DIMENSIONAL LIGHT ARRAYS TUTORIALS .. Also thanks for testing the MAX tutorial files. PDF file format so you will need the free Adobe Acrobat Reader to be able to view.
A photometric web is a 3D representation of the light intensity distribution of a light source. Web definitions are stored in files.

Many lighting manufacturers provide web files that model their products, and these are often available on the Internet. We as artists can use them to replicate the real life phenomena of light in 3d. Go to the Lights tab, choose Vray from the drop down list, and create a Vray ies in the right view.
Then instance it below all four steel holders. Color Mode If you choose this option, you can change and affect the light intensity through the color picker.
Temperature Mode Allows you to accurately change the light intensity through the color temperature. Power - Determines how bright the light will be.
This will cause the default lights in the scene to be switched off. Also, change the min and max subdivs as shown.

This mode will saturate the colors based on their brightness, and therefore, will not clip bright colors, but saturate them instead. This can be useful to prevent Burn-outs in the very bright areas for example around light sources etc.
Also, change the Preset to High, hsph subdivs to 50, and interp samples to Irradiance Map Computes the indirect illumination only at some points in the scene, and interpolates for the rest of the points. The Irradiance Map is very fast compared to direct computation, especially for scenes with large flat areas.
Current Preset Allows you to choose from several presets for some of the irradiance map parameters. Hemispheric Subdivs HSph.

Smaller values makes things faster, but may produce blotchy results. Higher values produce smoother images.
Each of the bounces in the path stores the illumination from the rest of the path into a 3d structure very similar to the photon map. In the Light Cache put for subdivs and 8 for no of passes.
The Subdivs determines how many paths are traced from the camera. The actual number of paths is the square of the subdivs the default subdivs mean that 1 paths will be traced from the camera.
Step 15 Your settings for the test render are done. If you hit render now, you should see the same image that was shown before. Now all you need to do is apply the materials, and increase the Irradiance Map and Light Cache samples for the final render. The basic parameters that will be used in materials are: Diffuse The diffuse color of the material.
Roughness - Can be used to simulate rough surfaces or surfaces covered with dust. Reflect The reflection color. Reflection Glossiness Controls the sharpness of the reflections. A value of 1.
Open the Rendering panel use the F10 short-cut key , scroll down into the Common tab, and click on the button with the three dots in the Assign Renderer roll-out menu. We therefore need faster feedback to make any adjustments and changes. Open the Rendering panel again and set the Output Size to x Fig Create a Target Direct light and position it as Fig 06 www. You will also need to copy the parameters for Hotspot and Falloff from those detailed in Fig Render the scene again Fig The scene is almost totally black, so we need to create at least one other light source coming in from the two windows on the back wall.
Create an Omni light and position it as Fig 09 shown in Fig09, right between the two windows. Make sure that the light is inside the cabin, as we need it to light that area slightly.
Set the Multiplier to a low value, like 0. Also, set the Start to 1,92 and the End to 9, Now there is much more light, especially at the back of the cabin, but the scene is still way too dark.
We need some bounces of light over the entire scene.

Create a sphere that surrounds the whole Fig 11 Open the Material Editor and create a new Fig 14 Standard material. Also, set its Self- Illumination value to Fig Set the Preset to Draft and render the scene.
This time the render will take a little longer, since we enabled the Final Gather feature of Mental Ray. This option takes care of the secondary bounces of light, or indirect illumination. Set the Final Gather Multiplier to 3 and render again. Now we have some more light, but we need to tweak the FG parameters a little Fig Set the Diffuse Bounces to 10 and render Fig 17 again. Render the scene again. Now it looks better FigNow all you need to do is apply the materials, and increase the Irradiance Map and Light Cache samples for the final render.
Learn and enjoy. The above rendering settings are good for test renders, but for production quality you will need to increase the samples for the image sampler, Light Cache, and Irradiance map.
In the Shadows group, choose Shadow Map from the drop-down list. We just need to extract the areas of the image with more light. Click Render If the object is still too dark, add more fill lights. Lights affect the scene directly, whereas light 5 has been placed in a downward direction, and will affect the scene in an indirect in the form of bounced light. Then instance it below all four steel holders.
Smaller values make the image darker, while larger values make it brighter. This will cause the default lights in the scene to be switched off.
