I have an issue with the Psunami Air Optics shader: when I try to render a scene with the light source/sun in front of the camera, part or all of the sky dome turns black (possibly any part of the sky dome surface at an angle greater than 180˚ from the light).

Psunami 2.1.3, EIAS 6.5, OSX 10.4.11, PPC G5

Anyone else have this problem? Any workarounds? It even happens with the tutorial files included in the documentation.

thanks

Hi, Simmon

With EI6.5 try to specify a little transmission for sky dome group (Material Dialog, Transmission Tab). For example, transmission color = white, value = 0.001 (just not zero)

Yeah, setting the transmission to anything but black worked. Blair wrote just after I left work last night. Voila!
