3d: mental Ray settings for the Aerial Shot





Moreover, the illumination inside and outside the buildings was achieved by inserting self illuminated objects with bitmaps of interior and exterior night photographs assigned onto them. The self illumination (glow) values and bitmaps differed from object to object.
As previously mentioned, these self illuminated objects had their physical properties set to: not to receive or cast shadows;not visible to the camera and not visible to reflection/refraction.

For interior shots, depending on the camera angle or/and camera shader (i.e. Wraparound(lume)); it may prove to be troublesome; if this is the case, avoid using this technique. If your interior scene requires too many physical photometric lights, try to be "economic" with their settings. By that I meant disabling the "shadows" function of some of the less relevant lights in the scene.
The trick is to achieve the same result with decreased rendering times.

Shadows cast by physical lights often contribute a great deal for the final rendering times.
To compensate for the depth in the scene, use the ambient occlusion on diffuse toggle of all objects.

I have just been informed that some of the contents of the book had been stripped in order to keep the page count down to 336 pages.
This is good news as I can now share this content with those that visit my blog.

As previously mentioned only one standard skylight was required to emulate the overall "fill light"(i.e. blue).
