I have learned a bit about the GeoDecalFrosted material type:
The melt system is only effected by the windshield deice. (SDK needs this info)
The blast system is only effected by the Structural deice. (SDK needs this info)
Changing the structural_deice_type in the systems.cfg will update the Blast system as expected.
So in reality the settings names was never made to match the structural_deice_type selected. So again melt is windshield deice and blast is structural deice. We need to have 4 systems. Windshield sys, Structural sys, Nacelle1 sys, Nacelle2 sys. Then we can use the systems.cfg to choose which type of system. Bleed heat or boots and vacuum and of course melt time.
The SDK needs to be slightly updated as all the labels and info is not accurate. But my suggestion is what we really need and hope to see this in the future.
@FlyingRaccoon I have a question for you. Is there anyway for now to use no melt or blast and have ice build up by weather only which we know works and then write a code to slowly hide the mesh as if I had nacelle bleed air? With the current windshield deice and structural deice working perfect I can’t find a way to make my nacelle deice system, except to use a visibility tag and just hide the ice when the ENG ANTI ICE:1 variable is true or ENG ANTI ICE:2 is true for another nacelle.
