"Rocket Engine SupportsWarpBurn" Not Actually Supporting Warp Burn?

from what i remember from using it in Stellar Neighbourhood, ion engines sometimes have a plume and sometimes they don't

@Zenithspeed Does the plume persist through timewarp?? What I'm trying to do is make a plume for my "fusion engine" (xml edited ion engine) for my interstellar vehicle, but I can't find a rocket in which the plume persists through timwarp. So far I've been using a long line of transparent RCS thrusters. Those plume do persist through time warp burn.

kinda sad, one of my OP crafts uses a heavily modded legacy Pixie with warp burn enabled, hopefully it won't get too broken

@Zenithspeed Yeah, I tested with the Apex, and still no behavior as intended. I guess that functionality was removed for the overhaul.

the versions of the prefab engines (Pixie, Mage, Apex (Titan was added during engine revamp update)) which didn't have procedural appearances and instead used a system identical to the ion engine and had different looks

@Zenithspeed Which would be the legacy rocket engines?

i believe this only works for ion and legacy rocket engines, but not the current rocket engines
