[Radiance-general] mixpict applied to files from tmesh2rad

[Bernhard Spanlang]

Hi,

I m using tmesh2rad to generate smooth surfaces for rendering in radiance.
tmesh2rad allows to apply a colorpict pattern to the surface.
Now I want to have a transparency value (alpha channel) for each colorpict
RGB value.
In the workshop it was mentioned a few times that mixpict could be used for
this and
I know Carsten has written a patch that allows to load colorpictures with
alpha channel.

If I create a radiance file with tmesh2rad can I add transparency from an
additional grayscale
image (alpha values) using mixpict ?

Thanks
Bernhard
