I've tried placing that giant controller everywhere on every planet type and size. Nothing...!!! What am I missing? thx
You need to build it over the 5 blue spots at the northpole of a metal planet. Note that there is a variant of the metal planet in GW (faction leader system), wich is not Anni-laser capable. Also the buildigns have a very large placement area (at least twice the model size) and MEX can easily get in the way.
I noticed somethign else today: Apparently building wrecks can block the Catalyst spots (no automatic removal of wrecks as with other buildings even in the current PTE build). Area reclaim them to get the space free.
It's a tad tricky because the blueprint doesn't snap into position correctly. Hold down the left mouse button and move your mouse to rotate it. Also make sure there aren't any other structures nearby because they'll get in the way. Beat brian to his own video. I'm awesome.
remove and reclaim any metal extractor that is very close to the catalyst point, they are surely annoying
Your engineers sometime don't want to build the catalyst when they are far, to avoid this problem move your engi closer to the spot of construction.
