I have downoalded an object from MakerWorld in Bambu Lab.I want to change the color of a pre-painted object. If I select the object I can easily change the color of the object, but what i must do to change only the color of the painted part?
You can do this by just changing the filaments in the filament window.
If you have used auto-sync to select the colours of filament you have, you can swap these around in the slicer (so they don’t actually match you AMS) then when you hit print you can manually assign the correct filament to the right slot.

That is a poor solution, as people use filament in strange ways, like using two colors, A1 and A4. It would be much nicer if you could swap filament for paint color in the Bambu-studio.
You can do just that as @Dylan.evans explained. Change the colours of the filament in Studio. The location slot in Studio doesn’t need to match the location slot of the filament on the printer. This is matched when you send the print to the printer.
Welcome to the forum.
I know that. But what happens if you have different materials in the AMS? The material is considered in the slicing process, so you can not just change the location slot when you send it to the printer.
But you can?

I design objects that use multiple colors - typically 4 to 6 colors. In my design software I create multi-bodied objects, with each body individually assigned a color/filament. This is why I always use .3mf rather than .stp or .step files - to better encapsulate the entire assembly as a multi-bodied object rather than as a collection of objects.
In Bambu Studio, selecting the objects option shows the objects as assemblies with bodies, each of which is assigned a filament, among other settings. To change the color and/or filament for each element, one only need assign a different filament to the corresponding body. Assigning all bodies to the same filament has the same effect as if all the bodies had been merged into one. In my opinion, organizing colors by bodies is much more controllable and predictable than painting in Bambu Studio, and easier to alter. Even though it requires a few more steps in the design process, the benefits are worth it.
In my case, it was not so. In the model, white and black filament was used and it was in A1 and A4 in the studio, while A2 and A3 were occupied by filament not used in the model. I had black filament in A2 and I moved it to A4, but let A2 empty. After slicing it was assumed that A4 is external filament set to TPU. So I have only a choice of A1 white and TPU (nonexistent) when I want to send the file to printer. There was not an option to switch TPU with A4. So I had to fill the empty slot with random filament and slice it again. It would be much nicer to select painted colors in Bambu-studio and assign them to AMS slots.
Actually its a solution as far as you do not sync or resync the AMS info on prepare screen. If you do that then you have to find the colours again in order to much the original file. In some cases also you will loose paint information. So is there any way to real edit colour painting or support painting on a pre painted project?
Be aware that when you change colors in the send to printer window that the purge volumes do not change to reflect the new colors. You can end up with a lot of color bleed in your model. Change from a couple of similar colors to black and white, for example, will probable get you a black and grey print.
