TCA cannot fire up engines of certain SSTO build from other mods

[kangjiajinlong]

Hi,

I am using TCA and I tried to TCA on a SSTO here (https://steamcommunity.com/sharedfiles/filedetails/?id=2446125572&searchtext=%E6%9B%B2%E9%80%9F), which is built using parts from KSP interstellar extended. The engines this plane have is called AntimatterRadiantDrive, which is from KSP IE mod. I found that TCA cannot fire up these engines when I use auto landing in orbit. I have enabled all modules in the SPH and everything else remains default.

Is this because TCA cannot control engine part from other mods (that is, it works only on vanilla ones), or is it something wrong?

I use KSP 1.12.3

I'd say your assumption is exactly the case. That engine does not have a stock engine module. Its engine module is named ModuleEnginesMagneticNozzle, which is unique to KSPIE. There are other such modules scattered throughout KSPIE's engine parts so you may want to take the time to identify them all to make it more worth Allista's while to try to develop support for that, if Allista is inclined to.
