3ds Max2008 - mr Sky Portal
by Joshua |
Autodesk 3ds Max 2008 began its customer shipment weeks ago and customers under subscription should receive their copies soon.
In this latest version, one of the most powerful features to me is the "mr Sky Portal". Let's take a look of what it is.
This is an interior scene with windows on the left.
We create a Daylight system and adjust the date, time, location and North direction of the system, in order to let the sunlight shine through the windows into the room.
In the Modify Panel, change the Sunlight and Skylight to mr Sun and mr Sky respectively.
Set up the new mr Photographic Exposure Control, and use Mental Ray (with Indirect Illumination > Final Gather On) to render the scene. A good rendering in result.
Let's create a mr Sky Portal just in the outside part of the Window, and make sure the Arrow of the mr Sky Portal is pointing into the room (by checking or unchecking the "Flip Light Flux Direction" checkbox.
Render the scene again and you will find an even better rendering with similar rendering time. For examples, you can find more detail shadows behind the bookshelves, the speakers on the wall, etc. The reason behind this is the mr Sky Portal helps collect all the Photons emmited by the Daylight system and use them into the interior scene. That is why we don't need to increase the parameters in the Indirect Illumination panel to obtain better results. |
