Radiance trouble when first time start up

[cdumontier]

For the batch renders, when I choose a illumination plan view at the height of the working plane (instead of a working plane), everything seems to be running like it should. Can someone tell me if there's a difference between those two "views".
Thanks.

ah that might be the problem, I've been told the batch/queues won't work for Working Plane images (something to do with it being a different Radiance calculation that isn't interface dt othe batch tool). That must be why it works for some images but not the working plane.

This is on the IES Dev team Radiance todo list but not sure when it would be available.

In that case, what's the difference between an illumination image set in plan view and a working plane view? I don't get exactly the same result images.

Hi,

These are different calculations really and I would expect they would give differing results.

Key difference here is the Illuminance image is looking at light reflected from the floor surface whereas the WP View is calculating light at the Working Plane (at a default height of 0.85m I think). The Way they are calculated is slightly different too so WP generally takes longer (it calculates at every point then generates the image base don the results at the working plane height while Illuminance just calculates and shows the illuminance at the surface (floor).

Hopefully this clears things up a bit,

It does clears things. I have to thank you for all the help you've given me. Thanks again!
