Layer Color Changes VANISH when adding object

I have a 3MF file, for some signs, with two color changes (first image). if I ADD another STL, it defaults to the primary color, but REMOVES (in PREPARE) my layer points for color changes. (2nd image). even if i DELETE the added STL, the color layer changes do not return (3rd image).

HOW to PRESERVE the color layer changes (in PREPARE), I KNOW i have to fix the primary color, i just want the LAYERS to stay intact, so i can then adjust primary color,change AMS colors if i have updated this, etc.

any help appreciated, thanks

how do you add the other STL? It should not affect these layer filament switches :thinking:

i just drag it in from a desktop folder.

re: “it should not affect….” … As you see, it does affect it… drives me nuts

maybe you are dragging a 3mf with more than just the geometry? because I tested and if I add a .stl it keeps the layer changes

thanks, but just dragging the STL…

just reexperimented, same thing.

opened the 3MF, has color changes. (base filament is #3, red)

drug in an STL, it takes teh default filament #1, white, i do PREVIEW, and the layer changes disappear

Did you ever find a remedy? I am having a very similar problem. I import a 3mf display stand and can put a layer color change in just fine. As soon as I import another file (Ive tried svg,3mf) it makes my layer color change disappear. I am just trying to add a logo to the stand.
