Thankyou for the response Dallan
So the main issue with the entire farm going missing i solved by splitting the MainFarmComp up into 4 sub comps so they render/load as and when should be expected.
Having said that the individual mesh_comps do still go invisible even when close in proximity so they should be within the load range. I feel this has 2 parts to the issue the first is we must as devs use 0.03 Sleep when removing/adding a mesh comp or it is also always invisible this is the first semi issue as it visually looks like a twitch when updating the mesh comp the second part in that they visually go but collision still is relevant to the player is a strange one and i cannot work it out currently. I thought maybe an LOD thing as I’m unsure if your award but sg mesh comps always use the lowest quality lod even if setup ie LOD 1,2,3,4 the mesh_comp always uses 4 which again causes another issue in the game.
So as i cannot easily change the MainFarmComp back now would this transform thing on a mesh_comp work as a workaround ? or is that only for the world streaming full vanishing act ?
Sorry for the slight confusing i think now these were 2 separate issues and it was coincidence that it happened full scale farm/single mesh and without working out the full farm issue (World Streaming) i just assumed it was the same issue.
This is the single mesh_comp issue and is not connected to the world streaming complex issue (The full farm vanishing)
