Next to the Space Shuttle, Vostok is the second rocket in the Flightgear repository. I haven't developed it myself (the developer would be Viktor Slavutinsky), but I'm now maintainer and have been busy over the last days moving the visuals to the next level.
(I've thought I'd separate Vostok from the FG Shuttle thread next door, since it's really a different project with different internals, different philosophy and different look and feel.)
One problem I had to solve for the ballistic entry is that the visuals and reflectivity of the capsule change quite a bit due to the fierce heat (the entry scorches are visible on the Shuttle TPS, but the effect is far less drastic there). I am moderately happy with the solution.
Here we go, the capsule and TDU in space, all shiny metal:
TDU separated and entering the atmosphere, glow just starting at the stagnation point:
Now the capsule heat shield starts to glow in earnest:
The plasma tail hides what I want to show, so here's around Mach 6 after the plasma has disappeared, still glowing...
... and a close-up reveals that the metal is no longer shiny but charred by the fierce heat, changing the reflection to something pretty dull...
... and braking parachute out, ready to deploy main chute:

Celestial ballet - the Vostok capsule has been separated from the TDU in preparation for entry and is slowly drifting away.
