Issues with lighting and Reality 2.5
I am using Reality 2.5 and LuxRender to render my images and I cannot seem to get the lighting right.
I have an outdoor seen so I added a sun.
When I render the scene I get an efficiency of just over 100% which seems a bit on the low side for a bright day...
When I add a diffuser to get rid of the hard shadows from the sun, the efficiency drops to around 90% and my model is somewhat grainy while the rest of the scene (which is not affected by the diffuser is fine).
After that I tried adding a softbox but I have to crank up the setting to make it affect.
If I change the power to something large like 4k watt my scene isn't affected although the softbox is really close to my subject.
Only when I change the gain to 10 I see something change in my scene and I get an efficiency of 103%.
I attached an image of the scene that I am trying to render.
The current image has a sun, diffuser and 2 softboxes and both softboxes have a gain of 10 and power output of 4k and efficiency of 57 lumen/watt.
Any pointers on this?
