 So you made an awesome auto material and you just wish there was an easy way to swap the textures. Not a problem. Let's say you want to replace the textures for the grass and stone on your auto material. Well to do that, find new textures that you like. Then in the material editor, click the one you want to replace. And then click this arrow to swap it. Do that for the normal map and the ORD, you're done. I want to go ahead and also do the same process for the stone textures. But yeah, you can replace things without needing to drag and re-plug everything all the time. Hope that helps and as always, hope you have a fantastic day and I'll see you around.
