Please try and improve import times with Bridge when VT is enabled

If virtual texturing is enabled at all, importing a single nanite mesh from quixel bridge takes a solid 40 seconds. This creates massive friction since nanite meshes are forced to download with 8K textures. There are two current options:

  1. Eat the wasted time cost and wait. This could be 40 seconds for a single asset or even higher than 10 minutes for multiple assets.
  2. Do not use virtual texturing and instead manually set all textures to have a lower max resolution. This also takes a loooong time and potentially can use up a computers resources, causing the engine to crash.

Obviously this is untenable friction that should be improved. Now this might be an inevitable part of processing VTs but other options could be letting us download nanite meshes with lower resolution textures (IMHO it’s ridiculous this isn’t an option), or even making it async similar to the interchange framework. This way we can actually get going and it’ll switch to the proper textures when ready.
There are a lot of issues with the bridge plugin but this seems to be the one that causes the most friction because there isn’t any good workaround.
