Live training Asset Bundles : question about HD/UD variant

Hi guys,

I have watched the Asset Bundles live training and I’m not sure to have quite understood the HD/UD variant explanations.

Will the HD/UD version be used as scene assets inside another scene or do they have to be themselves a scene ?

What I want to know/understand is : can I have a main scene with for example a character with a collider and be able to have that scene using a bundle HD/UD to provide assets ? If so, how this main scene would be set-up ? I mean, I would have to specify the character Sprite and define the box collider but depends on the Asset Bundles used, HD or UD, the character Sprite size won’t be the same and so the box collider. Do I need to change pixelToUnit value “on the fly” depending on the Asset Bundler version used ?

Thank you.
