Blender 2.81 Eevee lights clipping through objects when using volume shader

eevee volumetric light visible through objects
None of the other methods worked for me. What I did was I increased the radius of the spot light.
It will dim the light. Then I increased the power to compensate for it.

How to make glass dispersion behind a no dispersion glass? (cycles) and why light reflections is triangle in a round surface?
First of all, for the glass panel covering the core lens, the material setup makes no sense. With the Mix Shader's Fac set to 1, only the Glass BSDF will contribute to the output, so you can directly ...

Align & Scale Light (Portal) to Face
A Python script to do that.
The tricky part (I think) is to make it work whatever the face is: orientation, number of vertices, concavities... I guess that in this kind of cases, we want the light to ...

How do I fix this very rough sort of lighting in Eevee?
In Eevee, this could be either having too few render samples, or messed up Shadow settings.
Render samples
The default 16 samples should be enough already, make sure you have at least that.

What's the shading algorithm behind Smooth Shading?

There are several solutions here, either:
You don't have any object in your scene (you have hidden the only object of your scene, which is a cube, see the Outliner)
The strength of your light is not ...

Why does lighting on figure look bad at certain locations?
Solution is to add smoothing to object. I'm not super smart in blender, but as I'm finding solutions elsewhere I'm realizing these are fundamental options that nobody on stackexchange seems to know...

How to measure reflected light from 3D model in blender
If you use Cycles, save the output in EXR format; then, the units will be radiance in W/m2/sr. See: EXR output units.

How do I make an object reflect light through a volume at a specific angle?
The standard Blender renderers (Cycles and Eevee) aren't really suited to rendering the reflected volumetrics due to how the light paths are traced.
However, if you're only interested in determining ...

How do I make an object reflect light through a volume at a specific angle?
You can not solve this in an honest way. The implementation of Cycles engine does not allow this.
The bright light in the volume is visible only because the beam knows in which direction the sun is. ...
