Is this possible in JNO?

another property you may want to consider the the corner radius

if you’re unfamiliar, it’s in the same menu as the pinch slider

when you find the setting, turn them up to a higher value, it should make the fuel tank look like a cross-section of a wing

@SmarsoAero yeah lider is the mod i meant lol

@RudimentaryCheezit I tried this on mobile but couldn’t get that effect, thx for the suggestion

@Zenithspeed Lider would be a perfect example, gotta check when I’ll come home, currently I am away from my home. So I can’t access to my pc

in SP that's made with hollow fuselage + fuselage cutting
in SR2/JNO there is no proper fuselage cutting, though that clamp distance thing in the hidden properties menu has a similar function (you'll need to trial and error it unless you have some mod)

it is possible

in juno, access to the part scaling tool, and increase pinch (not pitch)

it should create a similar affect as shown in the screenshots
