Make 3D viewport ground crack/hole have a glow effect?

[gamer8685]

I saw this devforum post recently, and I decided I wanted to find out how to replicate what was shown in the video.

Here’s my recreation of the ground crack

I based it off of this video by @Aziorux:

Roblox Studio 3D Ground Crack

And this image:

It’s a combination of Viewport Masking and this surfaceGui Portal Effect by @EgoMoose

How can I recreate this glow effect inside of a ViewportFrame?

---

I’m not concerned about recreating the mesh or anything. I’ve tried point light influence and layering neon parts, but I can’t seem to recreate this. This is also not beams or particles, as these only end up rendering above the viewportframe.

Can anyone help?

I think the hole interior walls have gradient decals applied to them, or at least that gives a pretty convincing result.

I’m sure there’s more going on in the shown images with cool particles and maybe some decal layering in the hole to give it more variance, but just using decals for the walls seems to get somewhat similar effect:
