With now UP3 guns adjustments it would be nice to have these visuals. Atm. it feels like firing lasers.
So you're on the right way.
Maybe if you're once on the visual trek, could you please consider adjusting Wr.Gr. 21 hit effects?
The Handbooks of Fw 190 Rüstsatz weapon-trials I have, give it a blast/severe damage radius of 30m!!! If you ever tried ingame
Werfers it's nothing compared to that, I can hardly differ small Flak louds from this effect, the lil pluffy cloud it produces, though I think it uses the Flak cloud effect too. I know it's not a direct aiming weapon, that you need to place these big grenades near a target, but then if it explodes 3m near an engine, I don't think there was some left after that in real-life. That a fortress flies like a swiss cheese is also clear, have book here with these lucky gals returning home, but it doesn't say they are unvulnerable to these Grenades. Maybe you can't add Damagemodel, but at least a proper explosion effect would be nice to have.
BTW. Thanks for work on this project, wish you all the best
