So I decided to get cracking with making a house by following Martijntje's tutorial, just so I knew I could do it. I'm having three problems: skyboxes (I have no clue what on earth I'm doing), env_lighting, and prop models. Now until this point, all my maps have been indoors so I have been lighting everything with spotlights and for the life of me I still don't know what I'm doing with skyboxes. If anyone knows a good tutorial (or even a page on the Valve Developer site) that explains how to make them clearly then please hit me up, I need to start at the beginning. Skybox aside, I've run into a rather amusing problem I assume a lot of other absolute n00bs have been hit with: a model error. Here's what it looks like in Hammer. Okay, so I have got my head around the concept. That doesn't look too bad. But when I compile it, I get this: Yuck! I don't know why it's doing this, in my previous two orange maps I have a working prop_dynamic in the form of a resupply cabinet and several prop lights fixed to the roof. I've only seen this happen on this map just now. I found some errors in the Compile Process window that may be of help. *** Error: Skybox vtf files for skybox/sky_tf2_04 weren't compiled with the same size texture and/or same flags! Can't load skybox file skybox/sky_tf2_04 to build the default cubemap! *** Error: Skybox vtf files for skybox/sky_tf2_04 weren't compiled with the same size texture and/or same flags!

Error loading studio model "models/props_2fort/gibs/miningcrate001_break01.mdl"! 10 I also don't know what I'm doing wrong with the light_environment. Here are the settings I'm using. I assume this only works properly if you set up your skybox correctly? Ambient - 248, 255, 100, 110 Pitch / Yaw / Roll - 0, 337, 0 Pitch - 45 Angle - 337 Sun Spread Angle - 6 It's kind of depressing that I could do so many things wrong on such a simple map. I knew I should have stuck with orange maps for the time being - I'm way in over my head here!
