I haven't posted in awhile. My system with my 8800gt has been down so I haven't had time to play too much. I just picked up a gts250 (no one around me has gtx's anymore). Anyway, I am happy to see the alpha development, and to hear that bump mapping is coming along. You guys rock.

today i also added spectral thin film coatings to specular and glossy/specular materials.
this is usefull for making soap bubbles, petrol coatings on water and irriscident effects.
looks like beta2 is going to offer a lot of handy new things.

also, what should i call alpha mapping ? 'alpha' or 'opacity' mapping?

Radiance

I don't care about the name as long as it works
alpha seems fine to me. Just wondering will white be opaque or transparent ?

Opacity map is standard name in other aplication

note: Radiance please add function invert map in opacity
thnx

yeah, white = opaque and black = transparent.
grey levels are partially transparent.

So 'Opacity Map' is ok ?

Radiance

opacity map its ok

Opacity map sounds decent, and is common most of the place.

Looking worward to playing with the thin film coatings, some sweet renders you have there.

i vote opacity mapping since octane uses physical based rendering, and alpha is not an appropriate term for real world materials.

ok

Opacity map it will be

Radiance
