YafaRay4tS v1.0.0

[trueBlue]

So, if I move all of the IBL controls to the top, you approve?

Now, I guess, I am not understanding the BG Light (alias BG Sky Light)
Without using Previews, it seems the BG Light is dependent on Use IBL and it has its own Samples (Not IBL Samples), and can be used with other BG types
So, why is being called BG Sky Light and why is it in the Sun Sky section?
If it is being used with the Sun Sky, why would you want both?
Does it use any of the Sun Sky settings?
Edit:
Use IBL can be used with all Background types and the Background Light

"Without using Previews"
Previews have no effect on the render. They are only for looking at. The render only sees the background settings, not the preview.

"it seems the BG Light is dependent on Use IBL"
I don't see that happening at all. Maybe you can share a scene.

These are all the Blender background panels. In YafaRay4tS it's all one giant panel.

Format below is ControlLabel(behind the scenes name)
Sunsky2 is Darktide Sunsky

Some controls are shared by all the panels like Diffuse photons, Caustic photons and Background casts shadows.

The Power(bg_power) control in the first panel is the same as the Skylight power(bg_power) control in all the other panels.
Use IBL(bg_use_ibl) is found in the first 3 panels Single Color, Gradient, Texture. The Sunsky1/Sunsky2 have a similar control Add skylight(bg_background_light).
IBL Samples(bg_ibl_samples) are in the first 3 panels. Sunsky1/Sunsky2 have Samples(bg_light_samples)

Add sun(bg_add_sun)
Sunlight power(bg_sun_power)

The Blender is easier to understand because it is multiple panels instead of one.

Background Light not belong in the IBL section. Second Samples not belong in the IBL section. They are for SunSky, not Constant, Gradient or Image.

"Use IBL Constant - Gradient - Image" does not have any effect on Background Light/BGL - Shadows or Sun Sky Samples.

Use IBL Disabled - Constant

.
Use IBL Enabled - Constant
This is the only way I can get BG Light Shadows

BG Light Shadows a very faint
Using Gradient, shadows can get washed out from IBL
Using Image, shadows get washed out from IBL
Using Sun Sky, shadows get enhanced (Lighter)
Using Darktide, shadows get enhanced (Lighter)

You can't have shadows from the IBL in Constant, Gradient and Image without IBL Enabled.
BG Light Shadows are faint because the light is coming from ALL directions, not one direction.
