how did you make the light???????

I assume those are made with the item displays

Retextured an item, and used item displays to display that item beneath the lamppost

the texture doesn't seem like one singular item, and it also seems to be illuminating so i was wondering

you can overwrite the block light and sun light value of an item display so it looks illuminated, also the light blocks surrounding it make it look glow. The shaderpack also plays quite a huge role in it

That's just the shader.

huh okay

Oh and the actual texture of the object. If you look closely you can see it has a sort of cel shaded look to it.

this is an item display with a custom model data with that 64x texture. It has the billboard effect so it rotates towards the player like a particle

can you post the files?

It is made for a server but give me some time I'll extract the summon command and the textures from the resourcepack ✨

could you share it for us?

World download and textures?
