MOD DEV - Dual Fuel Engine

[Makx]

Hi, I'm trying to create a hybrid liquid/deuterium fuel engine that I'm kind of basing off the LV-T30 and R.A.D.I.C.A.L engine, (using T30 model and parts of the R.A.D.I.C.A.L cfg) but i'm having difficulty stopping it using both fuels at the same time... I'm trying to design it for long haul flights to the Jool system using a single engine rather than several different ones...

Here's my CFG file, am I missing something to make it only use one fuel at a time, easy to toggle between using both fuels and get it so it only produces plasma when using deuterium?

Thanks

You'll need to use ModuleEnginesFX instead of the standard engine module. MultiModeEngine module only works with ModuleEnginesFX modules.
