Wall reveals don't divide all walls in to sections for individual material painting

[lshannonEQEBT]

So I am stumped. We have some exterior walls that are all the same wall type, that all have the same wall reveals placed onto them. On some of the walls (East and West facing coincidentally) the reveals divide the wall surface up into different parts that can all be painted with different materials. The same wall types (North and South facing) with the same wall reveals do not divide up the surface, so if you try and paint a material you can only select the entire wall. Any idea why this would be?

Create Parts after placing reveals and change parts material.

Split Faces and Paint?

I'm really trying not to need to do anything different, just curious as to why it would be working with some walls and not others. We could split the face, but any ideas why it would automatically be splitting the face on some walls at the reveals and not others? Is there a way to see if someone had already split the face on some of the walls manually and we just don't know about it? (there are multiple hands in this project)

I jus tried doing the split lines just to see, and since there are reveals in place, you can't actually place a split line because the geometry is already split. We could fake it, but if the geometry is already showing as split due to the reveals, then why can't I select them individually? Pulling out my hair haha

What I was suggesting was a possible explanation of how the walls were colored that way. If it wasn't done by Painting Split Faces, then I'd have to examine the file to see how it was done.   Post the file here if you want.

I don't think it would be working with any walls unless you split face the wall prior to placing reveals.

So a new development. On the wall that was automatically splitting the face by the reveals there was an extra revel near the base and we deleted it. Once it was deleted, all of the automatic split faces reset to a single face, and even if we put it back, the wall face is now not split. #stumped

Yes.  Another reason to use Parts.

Were you able to find solution to this issue?

I was looking for exactly the solution to this issue, it was quite nerveracking... and finally a team member gave me the answer! I am posting in the hopes of helping anyone still battling with this issue.
You have to use the split face tool. The thing is, you dont need to use it in every place where you want to change materials, only once per wall does the trick!  After that, the paint tool recognizes all of the different parts created by the reveals. In our case we made one line very close (0,0005m) to one of the reveals on each wall and that was it.
And that was probably the thing that was letting you paint the parts in some walls and not in others.

My mind was blown... What can I say, Revit wants what Revit wants...
