As stated in original thread - your volumetric box must be built to be slightly inside of the volume of the space.

This is the part which made me confused and build two boxes.

Fletch, thank you so much for guiding me through this period. Really really appreciated.

OK Fletch, here is what I discovered. I got the material "Volumetric" in my list now. Like you said, in Sketchup material dialog, select a material (color) edit it and save as Volumetric. This part done. And this has nothing to do with the missing part of light beam. As long as the materia...

Fletch, I think I know why. Let me confirm on few things and I will get back to you.

I guess the stage and the floor or whatever underneath the light source, when the surface doesn't hit by a light, the light beam doesn't "pass through" it.
Can you check the the skp file that I attached in my previous post?
And see what is actually going on?

Fletch, that's OK, doesn't matter. The problem still exist............ This is the light with angle of 25 x 25 Light 01.jpg And this is the light with angle of 45 x 45 Light 02.jpg And then I add a FLOOR......... Light 03.jpg Seriously, I have no idea................. :wall: :wall: :wall:

I added a "Stage" to your scene that you posted previously, no problem at all.
And a screenshot of your material editor, there is a Volumetric Material in your list. How do I get that?

Fletch, I tried what you told. But still the same.
I wasn't using Default Material, but still I don't see Volumetric in the material list. So I guess that's the problem.
Here's the new scene I tried with.

Hi Fletch

You said : You should always make the volumetric material a specific/unique material in your scene.

How should I do that?

I don't have Volumetric in the list.
