Learn how to apply a texture to an area light.
- [Voiceover] One way that we can control…a color of lights is through maps or textures,…and in this exercise we'll use a file texture…to drive the color and pattern of the light…coming out from this area light,…and it will be a sort of simple…poor person's image-based lighting.…Let's select that area light and open its attributes.…I'll use control A to open the attribute editor…and in the area light shape node,…we can simply click to map the color.…
Click on the checker icon to create…a rendered node as usual.…In the create rendered node window,…simply choose file, browse for the file,…click on the folder icon,…and we're taken the current project source images…and I've got an EXR file here.…Select that and we see a non color managed preview,…and that's our EXR document that will be both…the background image and the light source.…Click open and because this is an EXR file,…we need to change the color space here.…
Instead of SRGB, we want it to be raw,…and now the color looks correct in the sample there.…The very first time you invoke…
