attached is the same picture rendered with Eevee engine with the shader 'Principled Volume' applied on the left. I have used a Light 'Spot' for the torch. As we can see I get that glitch on the torch, sort of pixelated effect, highlighted in the red circle, do you know how to fix it?

Thanks. enter image description here


Lower the volumetric Tile Size helped, thanks. However why I can see the light through the body of the Torch? See the red dotted area.enter image description here

I get some improvements playing with 'Volumetrics --> End, Tile Size, Samples' and with 'Volumetric Lighting --> Light Clamping' Volumetrics Parameters

  • $\begingroup$ You need to tweak some values to make the volumetrics look better: In the Render panel play with the Sampling values, and also in the Render panel, under Volumetrics, play with Tile Size (lower is better) and Samples $\endgroup$

    $\begingroup$ As per the problem of the light leaking through the body of the torch it seems to be a limitation in Eevee blender.stackexchange.com/a/214915/85951, thanks @Geri for pointing this out. $\endgroup$

You need to lower your volumetric Tile Size. Keep in mind that lower values can drastically increase render times in more complex scenes. See which is the highest value you deem "good enough".
