Are the custom assets can cause errors with VAC?

Hello!

I want to ask you a question. When you believe your maps with custom textures and models do you keep the models and textures within the game files or do a folder elsewhere on your hard drive?

I'm afraid that may cause a problem with the VAC.

Thank you!

Thanks for your quick response.:)
