i ask because so far i failed making a window what a window supposed to do - letting light through...

Hi Collin.

I guess that the easiest way would be to make a specular material, and go from there? Maybe you have made the window glossy instead of specular, atleast thats what i think

Even though its more realistic to make glass have IOR of 1.6something, it can be a good idea to let it have an IOR of 1.0, that way light wont bounce around like crazy when going through... Is hell for path-tracing, until MLT arrives

Best of luck, and maybe some of the pros will step in and guide you better

Although it looks like a bug or something related to alpha mapping.

can't be done, in the upcoming release this should be possible (as soon as MLT is introduced)

thanx proupin - good to know...

if you use pathtracing and HDRI mapping, it will work, if not, then no go.

Hi,

There is no directlight through opacity or glass at this moment.
It's stated in the release notes.

We'll introduce this in the final 2.3 version.
