If a 4k texture has a LOD bias of 1 and the game is then cooked, only the 2k version of that texture is ever actually saved in the build, right? I always assumed the 4k mip is completely discarded but I’ve never seen it actually said that that is the case, so just need confirmation from epic before I start telling people that is true!
Thanks!
Hi Kevin,
Yes, that should be the case. In non-cooked builds it will bias the mip, but in cooked packages you should see the full memory saving too. It’s worth noting that in 4.11 there were a couple of known issues that could cause the LODBias to be applied twice (for cooked packages only), but those have been fixed for 4.12. I can dig out the changelists if necessary or you’ll automatically benefit if your team upgrades to the upcoming release.
Thanks,
Chris
