Well first off, Im a complete noob. Now thats out the way,
I was watching this vid and he’s using a 2.4x blender and I saw him hit “apply” as well as verbally state (along the lines of) “… and I’ll go ahead and set smooth and apply multires”. But as the video progresses, you can see him bring back the multires and change the settings, I thought maybe he was just making a new modifier (though you say multires isn’t a modifier in 2.4x) but it just doesn’t match up to what i was seeing in video. Here’s a link to what im referencing
I also just read that applying the modifier provides a more accurate rendition of what its actually going to do and I could sort of see that initially when working. And being such a noob, and following along in that video, I wanted to see that pixel perfect blend as I was working, its just neat, lol.
Anyway, I started suspecting I should just avoid apply after I started reading about the modifier stack and I guess your confirming this for me now. Now I get to start over on my little landscape and practice using those brushes some more.
