Realised the post is rather old however…
This is what I was trying to wrap my head around - Quixel bridge offer up ORD images that cover Occlusion, roughness and displacement in one texture, the blue channel being displacement - I’m trying to utilise just that blue channel so I can feed it in to the parallax function but it only accepts Parameter texture objects. I’m trying to give the team flexibility in future so they can use both, no idea what I can use to ‘convert’ it to somthing it can read.
I also get why wanting to ‘rasterise’ one of the channels would be contrary to what the engine is trying to achieve and would be a performance hit however I’m producing static path tracer renders so not really an issue.
