i feel funny for being so perfectionistic but let me show you:

after adding this mod my problem was resolved but then you added the scaling-settings feature so i set it to 2 to match the player model, very immersive. see: https://imgur.com/a/LnwRS2Z

hehehe.... then problem again! PIXELS, the vilain! see: https://imgur.com/a/8jjyGBA (looks like heavy-ship has depth-of-field on compared to gunship lol)

could you please make the other 2 ships match ''gunships'' sharpness?

thank you

It is no longer possible. This is the maximum sprite size as far as I know.

you could try rendering the sprites of heavy+cargo again.
see in the second image the gunship is fine.

its up to you how much effort you want to put in the mod.
thank you anyways.

This mod is my limit. I'm not a blender specialist and not even a confident user)
