Using Tools Textures - Part 2I'm going to be using the same tutorial map I created for the last texture. Simply because I've already got the main content needed for what we are going to be accomplishing here. Its another simple and easy texture to use as that is how we are progressing through this series, building up the know how on the easy ones and working our way up to the more complex and powerful ones. Covered in this tutorial: ~Toolsblocklight - Custom Shadow's for models with no info. ~Toolsblocklight - Custom Shadow's for window texture effects.
ToolsBlockLightNow this texture does what its called. It simply blocks light, and it's main purpose is to create better shadow effects or to stop light from passing through/below something that it shouldn't be. The source engine isn't perfect after all and neither are we, so errors are bound to happen when making lighting effects. So we resort to using our set of tools and this comes up, for many simple situations you'll be able to use this in texture and effect and not even realize it at the time. Some simple info/warnings before I start into this, and so I don't have to repeat myself a few times throughout here or answer questions later.This brush is NOT solid, it will not effect vis leafs or show up in-game. The Texture ONLY WORKS when its been applied to the ENTIRE brush, you cannot have any other texture applied to the brush other than toolsblocklight otherwise it will be rendered in-game as a normal brush, completly visable and effecting vis leafs. For this tutorial I used a smaller light map scale to better show off the effect, so if you are wondering why yours are not as crisp as the ones in the screenshots, adjust your light map scale on the textures receiving the shadows to get what you want.More information on light maps can be found here:
