Assigning UVW coordinates in an OSL network

- [Instructor] The way forward in texture mapping in 3ds Max … is the open shading language, or OSL. … In previous movies in this weekly series, … we looked at how to author OSL maps from scratch. … Today I want to look at OSL … from the perspective of anyone who wishes … to use OSL maps but isn't necessarily interested … in scripting. … Specifically, the way that OSL maps … handle mapping coordinates is new, exciting, … and gives us many options that we didn't have before. … I've got a simple object with an emissive material … so that we can see the map very clearly. … And this is just a box object … and it's got a UVW map modifier applied. … If we go to the modify panel, you'll see I've got a UVW map … and it's assigned to map channel two. … As you probably know, you can have many map channels … per object in 3ds Max … and you can use those to assign different parts … of your shading network. … In this case, I'm using it as a teaching tool … to show you how OSL handles map channels. …
