Sample Texture 2D LOD issues

[loud cypress]

Im trying to sample a mip map of a redner texture and im assuming youd use the Sample Texture 2D Lod node for it but no matter what i put into the lod level it always looks liek the normal texture sample 2Ds result

I don't think mips are rendered for render textures automatically. You'd probably need a custom downsampling pass.

Though, it does seem to actually do something according to the docs:
