Hi, I am doing a Maya for VFX course on Udemy (:lightbulb:COURSE LINK!!!:lightbulb:). I have two engines, and for some reason, they are appearing green in the viewport. I made a node based material in the hypershade, and when I right click the material, with the engines selected, and select apply to selection, nothing happens and they are still green. All of the other materials that are the same as the engines, just duplicated, show up. I attached screenshots.
