Is anything can solve the problem of opacity?

Birds and tower,birds looks right,but shadow is not,the opacity not work on shadow

Try switching over to the pathtracing kernel instead of the direct lighting kernel... Path tracing supports alpha shadows properly, however, it takes a much longer time to render.

Hi,

Beta 1.22 is 7 months old and back then alpha shadows did not work yet,
The current versions, and the 1.46b demo which you can download on the downloads page does.

Neither of those 2 demo versions support the resolution your image is rendered in though.
So I guess you're not using a 'demo' version.

Ya,i was use the new version at first time,but it tooks a bit more system memory ram(like the picture),so... :|

I don`t know what happened(maybe gtx260 or winXP 64bit isn`t good for the new version? :shock: )

Sorry but i don't understand your question,
also, how do you render at this resolution when the demo versions are limited to a lower one and they can't be changed ?
