should all be working fine, can you show some code?
the only obvious issues i can think of are;
- positioning, make sure they are actually near or infront of the player (easiest way is to position it at the hmd position then use moveobjectlocalx/y/z), if you are inside the object it won't render
- the camera draw range, make sure you are setting the near and far ranges to a good level and it's not cropping the object from being rendered
- scale, the object might be too small as vr has it's own scale - though you say you already tried it
if you still cant get it to work then just copy the code from the example demos and see what youre doing differently.
