with my custom pack of 200 mods i recently added the latest bluepower and qmunity lib an noticed that items are not rendering in the tubes or magtubes for some odd reason, also this pack is on a server if that helps.

Hmm this doesn't occur to me

No longer an issue with newer versions see Work in progress / Project for further details.

ok a lil bit more testing and this is weird like for example when a transposer ejects items, the tubes won't render the items but if i break a tube before the items reach the chest and the items are bouncing back to the transposer the items are rendering.

Yeah, that's a known issue. They don't render until they reach an intersection. We're still trying to figure out why.
