use the shape producers to generate 2 Cu--Cu--:--Cu--Cu, and stack them together.
A ridiculous render error happen (showed in picture)
#[v0.1.1] Render error when stacking
stray moss
orientation seem to be ignored
It may only determine by the lower layer shape
indigo vessel
this has been found before but I can't remember if a report was made, either way iirc it was discarded as it only happens with shapes not possible to create without cheats
stray moss
but the render error is happen when stack on to this kind of shape
indigo vessel
well the top shape isn't possible to create without cheats
stray moss
shape in form shape:gap:crystal also create this bug
indigo vessel
it also looks like the bottom shape isn't creatable, unless there are pins on the bottom layer that I'm not seeing
ornate reef
||an Corner Scaffolding Build can make the lower shape, with or without the bottom/middle pins, also if you do an crystalizing before the stacks for the Crystal Corners||
To be sure OP need to post the Shape Codes
indigo vessel
well it looks like the bottom shape's bottom layer is fully empty, which isn't possible
ornate reef
No then it is not possible indeed
as said to be sure i need shape codes... i do not always see the full shapes on belts...
stray moss
bottom shape is this one --------:CucrCucr:P-crP-cr:CucrCucr
