it’s been a long time since my last post. I was busy trying to get somewhere with radiance and blender. The image was created with a modified version of the radex script. If there is interest I can give more information on how it’s done. The scene does not contain any lights, it has textures, reflections, and radiation. And I did not go for photorealism I know, but for interior lighting studies radiance rules.
You must be warned again, it is NOT a finished product, but it has a lot new features to the original script:
Set time and date and location
Adjust quality to medium and play only with the most important radiance parameters
Textures are possible, although limited
The radiance mkillum type is fully implemented, use it for windows
Adjust ground plane reflection value
I found some basic tutorial I have started some time ago, I have too many other things right now to make it really complete, but I have updated it anyway and here it can be downloaded (hopefully)
