With Octavia Prime release, I would like to adress a problem I have with the visual effect of "invisible frames". Currently the choice made by the developers is an hybrid one, between realistic and non-realistic visual effect. On the screen, we do not see the Warframe (realistic) but we see the shape of the Warframe with, inside, a floating cloud/ smoke of the energy color we chose (non-realistic). So technically invisible warframes aren't invisible on screen. And this is fine, players don't need a realistic invisibility effect to understand that their warframe is invisible.
