What I expected to happen: Conjured light provides light source.

What happened instead: Conjured light is created successfully, but it does not provide light source, only rendered animation/texture. I tried updating Psi and Forge, but behavior persists. Light block behaves normally in the 1.15 version of Psi. Thank you.

I mistakenly gave you a duplicate of the Psi version. I meant to give you the current (1.16-87) and the previous.

I tried this without Optifine (as your instructions read), and it works fine. Apologies. However, Optifine did not interfere with this function in my 1.15.2 instance (Which was something I did check.) Again, my mistake.
