Post tutorial Report content RSS feed HD Video Tutorial - Optimization 1: func_detail

Learn the basics of optimization, learn about leafs and portals and how to keep their numbers down using func_detail to increase compilation speed.

Posted by on - Intermediate Mapping/Technical

Rundown
First there's a quick theoretical walkthrough of how leafs and portals work. Then the problem is presented; round shapes and details.

Then we open up hammer and create a cylinder, we compile the map and see a large amount of leafs and portals in the compiler window. Then we tie the cylinder to the func_detail entity and compile the map again to see that the number of portals and leafs have decreased a lot.

Please give me a comment telling me what you think.
Also, don't forget to give me tutorial requests!

you could have loaded the portalfile if you were using the EP2 engine to show exactly what the portals looked like before and after.

What's the difference between a normal brush(not func_brush)and func_detail besides the fact that it reduces leafs?
