Why cant you add a “change filament” option to a layer if you are printing merged objects?
Example:
1.) I can print a keyring with text on the bottom layers using 2 merged STL files (reversed text)
2.) I can print a keyring with a Hueforge image on the top faces using a ‘filament change’ at a particular layer.
I cannot print a keyring with text as above and then add a ‘filament change’ for the Hueforge image.
Why not?
It would help us help you if you provided at least a screenshot or much better, a 3MF.
I merged some objects on the plate together, put a “cut” type text on the bottom, and added a color change
You’ll need to be more specific? Works for me
In this example, the text and lid are STL files added together (viewed from below) so that I can have different colour text but if I try to add a colour change higher up it is greyed out
Are either of the two items shown in the screenshot painted? Painted objects can interfere with other feature choices.
If they are, try removing the paint and instead select each object in turn and set the filament colour it requires.
I assume you have at least two filaments as I can see red and blue, I can’t see the view type you are using as that is cropped out, but it looks like filament. I mention this only as I needed to know you have at least two filaments, if you only had one this menu choice would be disabled anyway. You do appear to have at least two though.
If the removal of paint didn’t work or paint wasn’t part of the equation, there is another way.
Assuming the objects are merged, you could use a different technique to change the filament colour at different heights.
Height range modifiers are very powerful and do far more than change colours, but, we will focus on that.
If you have not explored the height range modifiers, give them a look. You can control so much with them.
They are in addition to the other varied modifiers available.
Having your 3MF, would let me confirm my thoughts.

Here is an example. I would need a filament change at layer 18 to white
The height range modifier I suggested solves the problem.
I set the range as below to get your layer 18 upwards as white.
From underneath showing the two colours you had, plus the layers at the top are white.
I do not have the option to change the filaments next to where it says:
Range 1.52-2.24 (mm) See attached screen shot.
It is the last bullet point from above.
Look at the bottom of the screen.
It is here where you add/remove and edit all the ranges.
You can also edit just one by selecting it.
That is exactly what I have done but as the screen shot shows, there is not an option to change filament
I showed you a much taller screenshot than you are providing as it sits right at the bottom of the screen.
I made the window shorter for the second image I showed you.
Make sure you look right at the bottom edge of the window.
I misread what you said, that is on me.
Can you see it in the file below?
Be aware, I am on version 2.0.x, you are on v2.2.x.

I just added a second Layer range by clicking the + at the bottom of the screen and now the options to change filaments have appeared.
If I delete either layer then I lose the option box !!!
I suspect a bug in the v2.2.x branch.
The good news is, you can add as many as you like and if you do not change any settings, it still works fine.
At least you have a solution.
Thank you for your time and solution. I will try a reboot later to see if that might help
