Did you check out the link I gave you above? You could check out my PG from this post
In the inspector, unfold the ‘Materials’ section and check on the material named “Mat_Neon_Atlas_1”
You’ll find that.
- It’s a PBR Material
- It has an emissiveTexture
- the emissiveTexture.level is pushed far beyond the standard value
Also:
4) We use the glowLayer instead of the highlightLayer.
Not shown in the PG, but can download the file mentionned in my post.
- The emissiveTexture is an alternate version of the diffuse/albedo texture to which I have added a blur to simulate a diffuse light effect. This blur together with a high emissiveLevel will show even when in the distance from the camera.
May be I’ll let you first discover a bit about this solution. And then, there are also other solutions. As cedric says, it kind of depends on your use case.
If I manage to free some time later today, I’ll try to illustrate the solution mentionned above (not a promise but I’ll try).
