[Radiance-general] Fwd: rcontrib for rendering - missing required modifier argument

[Christopher Rush]

What do you use to view the HDR image? Try typing:
ximage -e auto window_000.hdr

This will automatically adjust the exposure of your image upon initially opening the file. It could be that your image does have non-zero values but the exposure is skewed in your viewpoint making it look black with the default exposure value.

Or type
ximage window_000.hdr
then hit the ‘a’ key while ximage is active to view it with automatic exposure
while ximage is active you can also hit the ‘=’ key and click a point in the image to adjust the exposure according to various points in the image

However, generated window_000.hdr file does not have light. It is a black image, even though, the render generated by rvu of the room it is ok.
Do you know why does it happen?

Thank you!
Kind regards,
Urtza
