Relatively minor, but the the clock side of the logic cabinet's model interacts weirdly with smooth lighting, as shown here:

It also seems to vary depending on orientation; when the cabinet is facing north or south, the effect is much stronger than when it's facing east or west.

Try enabling experimentalForgeLightPipelineEnabled in forge-client.toml. Without that option you'll get some weird lighting on IE conveyors as well.

Ah yep, that fixes it!
