Sorry for the late response, I apparently didn't get a notification for this issue.
Anyway, to answer your questions:
I made the material of the text emissive. See the Emission section in the Spatial Material documentation. Then, I enabled the Glow post-processing effect so you can see a halo around the text.
The text mesh itself was made in Blender. I just imported it into Godot.
Hi Bauxitedev!! Thanks for your Volumetric Fog demo!! I'm using it to learn Godot 3D.
But I am failing to understand how you did some things in there, and I couldn't find any other way to ask you these questions except with an issue.
1) How do you make the text glow?
2) How did you make the text shape?
cheers!
