Paint by Layer issue/request

I’m having an issue where I’m trying to paint by layer and have the entire layer below certain lines or above certain lines a single color. When I do this on Bambu Studio it only does the outside of the part and the center of that layer will be a different color. In ORCA slicer it would allow me to paint the entire layer. This saves a bunch on filament changes. Can we get this fixed or have an option for paint penetration on the layer setting?

Maybe I’m not understanding, but it works just fine for me. I painted a few layers in a cylinder and it goes all the way through just fine. I’m using Bambu Studio 2.0.3.54.

Can you try it on a layer that is not the top layer? I get mixed results. On this model it did it on all the layers except one. And on that layer it only did it to half the layer. And that line will be visible on the outside of the model.



On this model the bottom layers are only on the outside (Yellow was the paint by layer.

After going through it. I think its selecting only half a layer based off the paint height being in between layers.

I’ve found that to get perfectly clean color layers using Paint by Layer, you need to calculate the correct values based on your slicer settings. For example, if your initial layer height is 0.16 mm and your layer height is 0.20 mm, you can use the following formulas:

INITIAL = 0.16 (initial layer height)
HEIGHT = 0.20 (standard layer height)
LAYER = desired layer number

BOTTOM = INITIAL + LAYER * HEIGHT
HEIGHT_RANGE = HEIGHT * (some integer)

By using this formula to set the “Bottom” and “Height Range” values in Paint by Layer, you can avoid issues with partially painted layers. I do hope they fix this issue in the slicer.
