I honestly don't know a lot about shaders. I played arround in unreal engines shader graph and wanted to get into that when unity released shader graph and the new render pipelines. Never really got arround to that though.
The standard shader is not bad. The thumbnail scene is just simple materials (with the standard shader) that have either emission or a lot of reflection.
The glow then comes from the bloom post processing effect.
Added color grading set to Aces and a vignette to make it more cinematic.
To be clear ,we didn't write any shaders for this jam, but piecing existing ones together :)
