#[1.0.3-rc3] Shape preview clearing after painter

I noticed that the painter is not showing any shape, which clears the preview for machines after. The painters have blue paint flowing and are painting normally, but the display is not showing up. I also have made sure all lines from the pattern/fluid source havent been cut and none have. I let it run for about 10 minutes and it produced the correct shape, but no display for it. Any reason why it wouldnt be showing up?

Shape preview missing on painters without color and lines not updated
Done • Priority: Highest • Fix: 1.0.0 Release • Resolution: Done

Shape Previews on Painters do not appear until the Painter is filled with paint, even though a preview should be shown regardless. Additionally, Shape Previews on Conveyor Belts connected to Painters are not updated when the flow is cut, leaving stale previews until the player modifies the belt or pipe layout. The issue was reported with a test savegame. It was later marked as resolved after a prediction refactoring made the bug obsolete.

Shape Prediction not existing when shapes are painted
Done • Priority: High • Fix: 4 - Early Access • Resolution: Done

Shape Previews are not appearing at the end of Conveyor Belts after shapes have been painted. The expected behavior is that Shape Previews should be displayed at the end of the belt to show what items are coming next. However, after shapes pass through a Painter, the preview visualization disappears from the belt end. The issue was reportedly fixed but remains inconsistent, with an additional related bug created.

Prediction missing after painting
Done • Priority: High • Fix: 4 - Early Access • Resolution: Done

Shape Previews are missing after painting a part, potentially after paint goes through a Space Pipe. This issue was supposed to be fixed but has been verified as still occurring in version 23.1. The bug prevents players from seeing the predicted output shapes after the painting operation, which impacts the ability to plan and verify factory layouts. According to the discussion, the fix was not consistent and a separate bug report was created.

The direction in which a pipe is built affects shape prediction in painters
Done • Priority: High • Fix: 1.0.0 Release • Resolution: Done

The direction in which a pipe is built toward a Painter affects whether Shape Previews appear on the Conveyor Belt. If the pipe is built in the normal flow direction, the Shape Previews display correctly, but building the pipe in the opposite direction causes the Painter to show no Shape Previews. The issue can be reproduced by placing a pipe correctly, observing the preview, then undoing and rebuilding the pipe in reverse. This was marked as resolved following a prediction refactoring.

Painter won't show predictions when connected to two fluid tanks
Done • Priority: High • Fix: 1.0.0 Release • Resolution: Done

The Painter does not show Shape Previews when connected to two or more Fluid Tanks. The issue is triggered by having multiple Fluid Tanks attached to the pipe system feeding a Painter; removing one tank resolves the problem. Adding a Fluid Tank or Fluid Launcher on a Pipe feeding a Painter also stops the prediction from appearing, with the length of the Conveyor Belt and placement point affecting the behavior. The Painters still output Shapes correctly, so only the Shape Previews are affected...
