I am just starting CS:S mapping today, and have a few questions:
1. Is there an equivalent of the "Null" texture from CS 1.6?
2. What exactly are Cubemaps; Can someone give me a very brief, simple explanation of their purpose
3. Hammer is running a bit sluggish; How can I fix this?
4. Any other tips you have for a first-time CSS mapper?
Any help is welcome.
