Principia can't generate gravity models when stock planets are scaled with Sigma Dimension

[Starcatcher2009]

I'm trying to make a mod named RealBodies, which essentially just scales the bodies up using SigmaDimensions. However, it seemed that Principia cannot generate any gravity models except for Kerbol. Why is that?

(I'm sure that this has been discussed on Discord before. Not sure why you would expect a different answer.)

The error is:

F0802 21:33:23.805872 22164 ksp_plugin_adapter.cs:2538] missing gravity model for Plock

First, I note that there is apparently no Plock in your Starcatcher's Mods.zip, so it's really hard to understand what is happening.

Anyway, I suspect that you are adding a celestial named Plock by mentioning it in some initial state configuration. I have no idea how you expect that Principia will divine the physical characteristics of that celestial. The reason why Principia is able to find the characteristics of the Sun is presumably that you are inheriting it from the RealSolarSystem configuration that we provide. There is no circumstances under which Principia would magically generate a gravity model for you.

If you are trying to create your own celestials, please follow the documentation to provide the necessary configuration files. You can use as examples the ones that we provide with the mod for the stock KSP system and for RealSolarSystem.

Closing as this is definitely not an issue with Principia and we are not going to do anything with it.
