Something for you and the team: Babylon.js Playground
A variable width outliner using the jump flood algorithm (jfa), works with instances. I have not yet tested against thin instances. Nor made a proper class for it.
I ported it from 3. Refs here:
a) The Quest for Very Wide Outlines. An Exploration of GPU Silhouette… | by Ben Golus | Medium
b) Outline Post Process - #14 by manthrax - Jobs - three.js forum
The outliner doesn’t take occluding meshes into account yet. Do you have a quick fix ? or will your frame graph help?
Its a little expensive due to size of the rtts involved so maybe half scaling the tex and then upscaling the final result would help with mem. But I’m not sure if I want to continue development if your upcoming frame graph will make this obsolete.
Or maybe its worth a spot for the repo? Shrugs…
