pyluxcore: Issue with camera or tonemap???

Post by mick » Mon Feb 04, 2019 10:52 pm

Please help me! I'm getting crazy.

I generated a simple scene: open box, half of it covered with a glass plate, sun/sky exactly in zenith.

Rendered "normally" looks sort of realistic.

But I need to measure irradiation on the floor of the box. So I make the walls and glass plate invisible, and render with orthographic camera and TONEMAP_LINEAR. I'm not aware of relevant other differences. And now the floor below the glass is brighter (upper half) than the open half. Even more the center of the sun is darker. How can glass generate and invert light power?

I think I don't understand a critical aspect of the config. But what???
Before you ask, I don't use blender, just python. And I don't know how to reproduce my config in blender.

All files attached. Below the diff of scn files.

Thanks
