Can any one be precise in explaining

1 - The difference between Intensity and intensity scale in Uber Environment2.

2 - Max error and Max Trace distance settings and its effects in rendering

3 - is there any difference in lighting/ lights effects if i Increase the size of Uber environments (i.e., sphere size from default scale 100% to 1000% or more

I can answer question 3. The sphere is just a visual representation it has no bearing on the light at all. So scaling will not do anything. I generally hide the sphere in the Scene Pane.

Actually when Mapped you can see where the light will be the strongest by looking at the image on the sphere. You can then rotate the sphere and have the light fall where you want.

Which is why I shrink the sphere down to somewhere between beach ball and soccer ball size smile

There’s no way to set that as default is there?

Just because I may have a strong opinion doesn’t make it any more (or less) correct than any other, just that I feel passionately a particular way at that moment.

Other than editing the actual files for it…no.  The size of the sphere is ‘hard coded’ into it.

It just means it’s expensive.

thanks very much for your replies.

read ADAM’s tutorial already, but I could not find solution for my 1st point.

I could understand the “intensity” setting i.e by increasing or decreasing the % value the light intensity/strength varies.

++++

what about the ’ intensity scale’,  by changing the % value, which lights intensity scale effected.

In omnifreaker tutorial page its Description says only ’ Light intensity multiplier ‘

under what circumstances we should increase or decrease the value of ‘intensity scale’

hope u understand my question

thanks

No reason you shouldn’t simply shrink (or remove) the sphere and save the result as a scene subset file - that’s what the initial load is.

I must admit the Intensity scale has alluded me, well the reason it is there has. It did some tests a while a go and to be honest from a Viewport difference I see no difference in render, as shown below. What I mean about seeing the difference in the viewport is that when you adjust the Light Intensity you see a visual difference in light in the scene. When adjusting the scale you don’t see a change.

These 4 images are just made up of 3 primitives and Uber Outdoor Preset at the highest quality preset. Render quality low for quick rendering. As you can see the is no difference between the two pairs of images. I can use IrFanView to view image and I go flip back and forth and I see now change what so ever.

This is why I have no idea why it is there and have been searching for the answer for a while. smile

Have you tried running this tests combined with other lights, changing only the intensity scale of the light?
I noticed that if the intensity of the light set to 45 and intensity scale set to 0% will make the render look more dark ,so in daz studio 4.5 I do see different result when changing the intensity scale .

No adding another light source would deteat the purpose and not give the a clear indication on what Intensity Scale is for, that is why I didn’t put another light in. Adjusting the scale won’t effect other lights in the scene so I can’t see it making any difference..

Also using an Intensity scale of 0% effectively turns off the light. I just tested it and it rendered totally black.

Final light color = Color * Intensity * IntensityScale. 

Yes, it is a little redundant, but the main reason for the adding the control was to more easily allow for intensities > 1.

Thank you omnifreaker for confirming that.

My advice is anything lower than 100% intensity use the to main Intensity slider. The Intensity scale is handy when or if the need arsies to go above 100% intensity without blowing out the scene with light while building it.. wink
