This may be caused by the renderer, it detects maybe the upper part, but renders it from bottom to top.

The legacy ones, does it too, but less.

And no, y allready observed it too, the walls are "solid" from start to end, the model also. Dunno why the game renders it, that way.

I've made blender to merge any vertex, etc. No results, one single piece.

Oh y understand you now, well you have to take as reference and squares that are drawn by the game.

The reason for 1x2 tiles is to make the corner and cross models look different to the vanila ones.

Ill have to build on a 2x2 space all possibilities straight, corner, cross and tee models.

The vanilla models (sorry Mafi) look ugly (corners, etc.) xDDD

Yes im aware of it, but y think this is internal bug of the game itself, since im not using any custom code

for creating the retaining walls. Must be something related to the terrain management.

What you need then is 1 tile piece, right?

They are all based on ingame ports/zippers.

If you use only the transport bars and connect them to the balancers, all directly the speed is near instant.

Cuz there is no "way" from input to output, they are connected directly, a bit cheaty.

Try turning them 180º.

Will investigate it, visualy it is possible, just adding few new models, but technically y don't know.

Allready made, they allow now a height of 25

Have patience, it seems to be something related to the bandwidth of COI-Hub, just a feeling.

hmm, y think y have done it wrong, y wanted concrete, didn't change it? LOL.

Will update as soon as y can, thanks for advice.

Lol, just done.

You must unlock using research, there is a new icon in the toolbar of the game.

There you go, thanks for advise...
