should be able to create "filters" to post process assets in memory only about assetgraph HOT 7 CLOSED

@chbfiv the maintainer is currently actively looking into making ABGT more efficient when working with large amount of assets (100K+). I think that with the steps necessary to achieve such improvements comes the need for virtual assets or configurable settings per production environment to achieve this.

By nature of AssetBundle the system requires data from filesystem to build bundle. Being said that, I think it is capable to procedurally create variation of sub-assets based on source (such as creating SD/LD from HD) and write it in cache folder, then use it as input to accomplish this.

Virtual Asset needs some deeper consideration before implementation. I am pushing this back to 1.3.

Update on this ticket.

I have added AssetGenerator node to dev branch, which you can generate derivative assets from incoming sources.

Currently the built-in Generator is only TextureScaler, it will at least do the job to create SD/LD textures on demand, give them straight to variant.

I hope you can try this feature and see if it works for you.

Note: current TextrueScaler implementation is very trivial - you might want to implement on your own for production use.

I will set this issue to resolved. Please reopen issue if this is not solved by AssetGenerator node.
