Hey everyone, I’m hitting a bit of a wall with Mekanism in All The Mods 10 Lite. I’m trying to set up a Thermal Evaporation Plant, but the multiblock simply won't "form" (no red particles or structural completion).

I’ve double-checked the wiki, but I’m clearly missing something specific to this version or just being blind to a simple mistake.

The Setup:

• Controller: Placed on the second layer (not the bottom or top).
• Frame: Using Thermal Evaporation Block for the edges/corners.
• Dimensions: I've tried a 4x4 base (standard 2x2 internal air space) and it's 16 blocks high (not counting full solar panel height).
• Valves: I have two placed (one for water in, one for brine out), but pipes wont connect.

The Issue:

Even after checking the corners and ensuring there are no "illegal" blocks inside the structure, the UI won't open and the controller remains inactive.

Is there a specific config change in ATM10 Lite I should know about?
Or am I just using the wrong blocks for the floor/corners?
Any help would be massive

Modpack: ATM10 Lite
