How do I emit light from within an object using a point light (Chinese Lantern)

I think Translucent BSDF shader is key of this material so check this answer. Or you can use Principled BSDF shader where especially Transmission parameter set to 1 will do the job. With Extra Curve ...

How to make cumulonimbus clouds?

VDB to Mesh + Sculpt ... Import some existing VDB cloud ... You can't convert Volume object into a mesh directly, but I just noticed - you can add some mesh object (like a Plane) and use Volume ...

How to make cumulonimbus clouds?

Thanks to @vklidu, I could make these clouds pretty easily, using the method in this this answer. Starting from an UV Sphere, model the basic shape of the cloud using proportional editing. Then Add -&...

Is it possible to ‘blur attribute’ for volume cube density?

so the reason to why the blur node doesn't work for the volume use is because it doesn't have topology, which the blur attribute used for blurring. The volume still has kinda like a point grid, ...

How to create high altitude clouds? (cirrus and cirrocumulus)

This reply might be a bit late, but I figured out a way to at least approximate cirrus clouds using purely volumetric modeling with noise and gradient textures. To begin, I tabbed into Edit mode and ...

How do I emit light from within an object using a point light (Chinese Lantern)

You could fake it with a Layer Weight that you use as factor between 2 Emission shaders:

Volume absorption with boolean difference, when smooth shading the cutter?

I guess in general you can say: the Boolean modifier applies the shading information of the cutter object to the generated surface created by the cutter. Since the cube is by default shaded flat, a ...

How I can apply noise texture shape animation on a geometry?

The issue with your second image is that Mesh to Volume - Density expects a single value (Float) for all voxels. 3D texture is not accepted. Volume nodes in GN are quite limited at the moment so there ...

import VDB file and start the animation at a certain frame in your scene

It is actually quite simple, in the settings for the OpenVDB File there is a Start value. This is the one on which you want the simulation to start. If you hover your mouse over it, the appearing ...

How to loop an imported VDB file

In the Volume Data change the Mode to Repeat or Ping-Pong depending of the type of the simulation or the effect you want to achieve.

Light not affecting volumetric cube, but only in specific project file?

Light Paths > Transparent under Render properties was set to 0 in my "broken" project, changing that made everything work as expected.

Density field for volumes in geometry nodes

You can only use volume cube for that. For the mesh detection you can use raycast for example:

Why does refraction + volume scatter cause a much darker result?

This issue still exist with volume boucnces, also without cast shadow. my mesh doesn't cast shadow, and I have all bounces set to whatever is a lot, and the combo refraction + volume still creates a ...

Why do volumes appear more dense when sliced with a bunch of transparent planes?

Missing some details here, shaders and light path settings would be useful. Some experimentation tells me that a transparent plane using Principled BSDF has odd behavior, I'm guessing because it has a ...

Why is blender stuck at computing volume mesh?

Ran into this - found out it was because motion blur was enabled. If you want to keep motion blur enabled for the overall scene you'll need to turn it off for the Domain by going to Physics > Fluid ...

How can I apply volume cube node with texture effect to different kinds of geometry?

For simple figures like a cylinder, you can check if the position of a voxel from top-down view is inside a circle. You can compare the result with texture using multiply or boolean and: Sphere is ...

Making volume clouds sharper

Obligatory warning that anything you do to increase volume precision will also increase render times, perhaps massively. Volumes are highly probabilistic, and any rendering shortcuts tend to decrease ...
