Love the idea of the mod, and your railgun artillery model is fantastic. That said, it seems to be currently incompatible with Combat Mechanics Overhaul, throwing a startup error regarding sprite rotations. If it's within your means, may I ask for a compatibility update?

Hi! Thx)
The CMO: https://mods.factorio.com/mod/combat-mechanics-overhaul?

Can you provide please more info about error?
- Factorio version (current stable or experimental)
- Maybe the game log file will be enough for futher debug process
- Provide mod set or save file without railgun artillery mod (for easy way for syncing modlist and settings?)

I've tested on stable release of factorio in combination with minimal modset base/space age game + cmo + railgun artillery mod: and all started fine ...
Maybe I've missed some settings or smth else

Okay, will test soon, including settings - maybe I've borked something on my own. If I still see it happening, I'll give you my log and what info I can. If I figure out it's something on my end, then my apologies.

Alright, here's what I'm getting with just Railgun Artillery and Combat Mechanics Overhaul enabled. Can't seem to upload the log file, so here's the pasted log: https://pastebin.com/8Rqy3hbL

• I tested in 2.0.66 both with and without any settings changed on Combat Mechanics Overhaul, both times with only these two mods loaded.

Hmmm seems to uncheck "High-quality animations" in Grapgics settings action leads to error....
Ok, I'll try to debug why it happens

Try pls 0.1.6 version, I changed shadow layer properties to be correct with non high-quality-animation mode. Locally the error has be gone on my setup.

Works like a charm! Thanks a bunch!
