Hey all again
I am going to make a custom gmod map for the game type murder i want to make it really nice with my own custom textures and basically have fun making a map for users to play just need a little bit help with a couple of questions, if you don't mind.

1. Where can i get free custom textures?
2. How do i compile a garrys mod map with custom textures?

I have made many maps before in gmod, was currently working on a facing worlds map but
it was already done and much better and more of a professional (team) working map and i got stalled.

So i was going to make a simple but good gmod murder map for murder, but its going to be more my level, light switches, water maybe some werather effects and custom textures.

As iv said i have made maps before on gmod with my own custom textures but i don't know how to compile the map with custom textures so everyone does not see a Black and pink checked world of hatred.

Thanks in advance!

Googling 'free game textures' gets a few results that look promising.

For packing in game textures, while developing the map you want the texture probably in the garrysmod/custom/ folder or something like that, find the place that any custom textures would go in a HL2 mod. This should allow you to load the texture in hammer, and it will show up ingame as well when you load up the custom map. It won't be baked into the map at this point however, so then you want to use this tool https://developer.valvesoftware.com/wiki/Packbsp

Then remove the custom texture file from your gmod folder, and test to see if the texture still works.

Thanks a lot huge help really sped up the process was struggling to find anything useful.
