no control over IES lights

Hi, hopefully someone can help.

No matter what I do, I cannot control IES light intensity - they always make my renders white!

I have an interior scene (by which I mean everything including the camera is in a box) I edit the IES light, select a .ies file, turn off my physical camera and sun as this tutorial suggests:-

When I hit render, its almost all white. Even if I put minus 10000000 in the power, no change.

The only thing i’m not sure about is if I actually have turned the sun off - I go to ‘environment’, click the little ‘m’ and set the ‘texsky’ to ‘none’.

Any help will be greatly appreciated.

Cheers, Matt.

Re: no control over IES lights

you need to control your physical camera. Try adjusting the f-number and iso. I dont think minus values have any effect on lights and i think its the same as a value of 0. If you want the sun off, just set it to a night time value in SU. Hope that helps, best of luck
