This is the same situation with the max plugin as well, no opacity or shades of grey supported, just white and black, either on or off.

A work-around to this issue would be to somehow convert the grey map information to black and white fine dither pixels (dots). Then it becomes a density approximation of the opacity shades which would be a 60% solution, with 100% being support of opacity maps.

Anyone know a technique in photoshop or painter for doing this?

convert to indexed color with two color palette (b&w), try some dithering methods to select the best one

Thanks, I will give this a try using the cinema4d plugin.

I think this will give a lot of room for new possibilities using this alpha-map approximation method for opacity maps in maxwell render!
