What happened?

The light and shadow I use is (photon). When placing the artwork, the pattern will not be displayed, but it can be seen after turning off the light and shadow. Some lamp models are not displayed. The painting model is the original version, and the lamp model is from {Chipped} at https://www.curseforge. com/minecraft/mc-mods/chiped
What makes the light hang horizontally {Amendments}https ：//www.curseforge.com/minecraft/mc-mods/modifies
When the light and shadow are turned on, the project framework model also does not display
I hope someone can help me, thank you!
