Hello, I have difficulty understanding English, but i try to explain issues

I encountered a visual bug. It occurs during the period when the metal enters the mold, until the appearance of a solid ingot in this form.

This black something is located only on the right side of the screen, and generally appears when you look at mold, and disappears when you turn the camera away. It also remains on the screen when you continue to look at it through the blocks, and it is noteworthy that the black spot makes the chests disappear visually from the screen

Perhaps a visual bug is triggered in combination with some mods

Also, if it helps, I attach a photo of the currently installed mods? play on forge 1.20.1 no optifine

I've encountered the same issue. Same version of tfcchannelcasting.
