Can you make a replacement for the vanilla turret art (it really stands out with the rest), for example this https://mods.factorio.com/mod/rp_gun_turret_1_art or maybe making a new one.

I agree it looks a little out of place. I'd probably release it as a separate mod because I get a lot of complaints that the mod is too big as it is.

I'm working on a companion mod right now so it won't happen for a few weeks.

Could that mod replace the other vanilla turrets sprites with your others (for example the Artillery)?

Artillery turrets are weird because they use a completely different animation format. My assets don't support them very well and the end result is pretty underwhelming. So I don't recommend reskinning it.

I've made it pretty easy for you to use these assets in other mods so you could release your own. A few other people have done this. It's only a few lines of code. I explicitly do not allow you to copy-paste the assets directly, you must use them as a mod dependency.

• RP Art Util - The core mod for using assets, includes examples
• Howitzer Art Patch PD - Example of how someone else used these to reskin another mod

I would do that but I have no idea how to make mods for factorio.

Neither did I when I started. Now's a good time to learn
