I noticed that the vanilla game has two separate files, vanilla and vanilla.winter. So I tried to copy all of those files into my mod folder but separate. Then I made my models and other additions to help add to the winter effect of the maps but it won't even use the models that I made. Any ideas on how to fix this?

Are your files in either media/overlays/your_mod/packages/vanilla.winter/[textures|sounds|weapons|etc..] or media/overlays/your_mod/packages/vanilla.winter/maps/map4?

Well, i just copied basically the whole folder of vanilla.winter into my mod but as a separate folder naming it "Winter". Then i put the normal maps in a different folder with all of my other models and changes naming it "Normal". I was planning on making models to add to the winter effect for guns and soldiers, but the game automatically uses vanilla models. I thought that maybe if I replace the soldier model xmls with my models it would use my models instead (using the same xml name). My mod wasn't fully updated to the newest version either, soo i had changed it and fixed for compatibility with 0.99.1 as well. But that still didn't work, I'm out of ideas sadly on how to fix this, and if you can't figure out a solution then its perfectly fine though.

I need some specifics about those folder locations to be able to help you.

Is it so that you copied vanilla.winter to media/overlays/your_mod/ named as Winter? That won't work, the game doesn't load such a folder as Winter there. You'd want to copy vanilla.winter at media/overlays/your_mod/packages/vanilla.winter. Then the game will use those files instead of media/packages/vanilla.winter when you enable the mod for a map that uses vanilla.winter, like map4 (Fridge Valley) or map12.

It also might be that you're not making an overlay mod at all but more like a complete content package which you pick maps from to load into, just like vanilla maps have it, so you'd have your files under media/packages/your_own_package.

I need more data

Your idea of naming the folder vanilla.winter may work, i will get back to you on that

I copied the vanilla.winter folder and named it that as well, here is the path, media/overlay/More Classes Mod(test)/ . The naming of the folder didn't work though, I had tried to replace the model with mine just to see if it shows. But it didn't sadly, it still used the vanilla models.

I understand now, you want me to do this media/overlay/More Classes Mod(test)/packages/(then the folder). The name has to be specifically vanilla.winter correct? Is that the same for my normal folder, should it be named "vanilla"?

So as of right now my path for the folder is media/overlay/My Mod/packages/vanilla.winter/factions, models, textures, etc. I tried running the mod like this and it crashed immediately.

Sounds like the loading now works then, at least there was a change

What does %appdata%\Running with rifles\rwr_game.log say about it? The paths where the resources are loaded from can be verified with that too.

10:22:27: OGRE EXCEPTION(4:ItemIdentityException): ParticleSystem template with name 'SnowFlakes' already exists. in ParticleSystemManager::createTemplate at ..\..\..\..\OgreMain\src\OgreParticleSystemManager.cpp (line 289)
10:22:27: : uninit comms

I'm assuming this is where the error occurred. It was at the end of the whole log, I was gonna copy and paste most of the log to here but i figured that would stupid and lazy of me. So i took the matter into my own hands, although if needed i can get the log for you.

Well played And that's indeed the problem; there's something different about particle systems that they can't be overloaded similarly as other files, IIRC. You should get past that by removing your_mod/packages/vanilla.winter/particles/snowflakes.particle.
