HDRI ?urgent!

[Andrew W]

Unless you've painted your matte painting in floating-point data your matte painting will not be a HDR image. There are ways and means of cheating this (see Hayden Landis' 2002 SIGGRAPH paper on "Production Ready Global Illumination" which has a shader that expands the range of a LDR image.) but these are often rather hacky fixes, though the one described in the Landis paper is one of the better ones.

If I were you, I'd use the matte painting as an environment map on an ambient light to do the fill lighting and then use some regular CG lights to do the key lighting, with some ambient occlusion to attenuate the ambient light.

If your matte painting is floating-point then you'll have to save it as a floating-point TIFF, EXR, or HDR format image.

Good luck,

Andrew
