It sounds like you are trying to change the filament color for specific parts of the model using slicing software. Instead of using the paint tool, you need to use the “split” or “dual extrusion” feature in your slicing software. This will allow you to assign different filaments to different parts of the model. Look for tutorials or guides specific to your slicing software for more detailed instructions on how to achieve this. Good luck with your project!
