Hi, did you check all settings of the mod? There is FOV setting. About animations - that is not about FCAV mod, we got decision to change them - improve. You can put into: YourFCFolder/Mods/FCAV/Music/Menu any your own custom music/sounds, including original soundtrack, so yeah, you can.
About Grass issues, check what shaders you using, as another variant, try this one: Lighing fix shaders cache maybe this will helps and with a grass too. Also be sure you have nvidia videocard and playing it on Vulkan render, or if you have some troubles with Vulkan, you can disable it. It is located in OpenFC folder, named as d3d9.dll file.
Hey.
I can`t believe I hadn`t seen the FOV setting before, lol, thanks. About the menu music, it worked, thanks again. As for the missing grass sprites, my bad, it was a wrong setting, "min vegetation size" was set to 2.2 intead of 0.
What about the auto ammo pickup, any way to restore it for the single player?
