Includes new code from odf. Mainly fixes and speed-up while exporting geometries.
Because the light intensity is raised, I have to use a very high fstop now in Lux if I use kernel: linear.
Better make sure all lights together don't exeed 100% in your Poser light setup.adp this is bad advice, keeping under 100%. The sun light must be 4 to 8 times brighter than any "bulb" type of lights. If you want a living room or kitchen light on, as well as outdoor lighting for looking through the window, you will need the kitchen light at, for example, 75%, and the sun light outside at 600%.
The total light amount is irrelevant precisely because you can adjust exposure in the target renderer. You can expose for out the window, or you can expose for in the kitchen.
Think like a camera. Do you, when using a camera, tell the sun to stop radiating at full power?
No.
If you're really thinking about accuracy, look at the EV value shown by the renderer, at the bottom right. If you are outside at noon on a sunny day, it should be EV=16. That is 256 times brighter than indoors.
Right, yes.
But we are in a stage where lots of people do a first try with their existing Poser scene. A Vickie, some props and 3 or more point-/spot-/infinite lights. If they don't get a result by pressing a button, they tend to reject Lux. Because for most people here a renderengine is fun, no science :))
