Hi @brs-sebascova !
Thank you for the detailed answer.
Just to make sure on point 1: by default the cooking process keeps all the LODs, but if using the setting explained by your link, the packaging will discard the LODs higher than the “Minimum LOD” specified for the mesh - is this correct?
What I’m after is not only reducing the tri count for the rendering, but also the size in order to improve the World Partition streaming performance.
And from your explanation, using solution number 2 should achieve that result as well.
