When linking materials 1 is good,1 is black, the other is white

[Hayden Brown]

When I linked them the color attributes names where different(Dirty-Vert or Dirty_Vert. and one was just Color not Base-Color). I got them named right but no change. Also they were in different configurations. like vert above color. I think it may have to do with add color attributes variety. 

Really Idk

Hello Hayden. I guess first make sure the names of the color attributes are exactly the same as in the nodes, letter caps and dash signs and everything, perfectly the same. I can’t tell by the screenshot because it is too low res.

After that check you assigned the same material to the other trees, one of them being white can mean it doesn’t have a material. Also check that all the trees each have the same color attributes in them, because if they don’t have color attributes by those same names, the nodes in the material wont work. So select each tree and go to their respective color attributes menu and check they each have one. And finally try turning up the world strength so that your scene can be better lit, right now it is very dark and hard to see what is going on.

Hope this helps you.

So it was really dark because i added dirty vertex to my Base-Color color attribute making it twice as dark. Then in the shader nodes i had dirty vert and base color input reversed in the overlay node ( at .5 Fac), making it even darker. idk about the black and white trees, I just sweeped all color attributes and started fresh.

Basically goofed on  everything I could in this lesson. just gotta take it slower and understand what im doin better. Take a break and come back. I appreciate response and your time. Always helps to have someone bring more certainty to the problem at hand

as for color attribute choices I went with:  base-color            Vertex-Color

                                                                                              dirty-vert               Face Corner-Byte Color

Idk what these are but I think it works fine

I’m glad you worked it out. From black to colorful, the tree is looking healthy again. May he long produce digital oxygen.

Yeah I second the comment by Omar. When you reference atttributes by name make sure spelling and case match exactly. Blender python attributes are type and grammar sensitive. Even if that wasn’t the whole issue it’s good to remember.

Don’t sweat making mistakes! You did the right thing by taking a break and coming back. Sometimes we are literally too close to these trees to see the forest (nailed that pun!)

@Bonkerz With Blender 3.2 the devs updated “Vertex Colors” to “Color Attributes”. There’s now 2 modes:

• Domain: Vertex or Face Corner
• Data Type: Color or Byte Color

Unintuitively, Face-corner and byte color is equivalent to the old “Vertex Colors” version from this course and everything pre-3.2. This can be confirmed if you switch to vertex paint mode on a mesh that doesn’t have color attributes. Switching to that mode will automatically create the old “Vertex Color” compatible slot.

Sorry for the confusion!
