Now THIS is a such a simple thing I didn't realize I needed! Thank you, sir!

Yeah, sorry, it was my fault. I had misunderstood something.

@Peter34
I tested out both mods together, the Console Edition HD Art mod does not stop it from working, either another mod you have is interfering or your empire does not fullfill the requirements to upgrade it.
You need to apdot and finish the cloning tradition.
The upgrades are also locked behind the tier of the capital building, each tier giving access to another tier of the clone vats.

I never get the option to upgrade the Clone Vats, and I suspect it's because this mod interacts weirdly with the Console Edition HD Art mod.

Oh yes, sure feel free to do that.

Would you mind if I integrated this mod into my mod Expanded Pops? (Our mods would not be compatible otherwise)

*value of the sustained clones on the building.

Hm, the way I made this work is by multiplying the value of the sustained clones, @clones_sustained_low which is 500 normally
It could be that another mod changed the value of the @clones_sustained_low, which in turn exploded the numbers of pops sustained.

Surething. Suddenly the vats were reading as providing 5k and 10k clone support from level 1 to 2. If nothing changed on this end, there must be a conflict elsewhere or likely a mod that I tested/removed is having a lingering effect. Something must have changed/overwrote a vanilla value. Will get to searching.

As for the Ancient Clone Vats, one third.
It exists now, it should hopefully work without too much issue.

If you could elaborate Jarren.
All in all, there should be a max of 6500 clones per planet with a Genomic Research Center, a fully upgraded Gene Clinic, and a fully upgraded Clone Vat.
The only other source of clones would be the ancient Clone Vats which each provide 2500 Clones.

Did the recent update increase the clones supported? If not I am likely having a strange conflict.

I wonder if same thing could be done with Ancient Clone Vats

Yeah, the Building Slot scarcity is absurd for some builds.

fantastic mod, between the medical centre, genomic research facility and 4 cloning vats you have to use 6 building slots just for growth normally. Thats too many, imo this is how it should work base game
