Current Behavior

To preface this is undoubtedly Optifine related, so not sure how easy to fix, or what your policy is on Optifine.

Had updated to the latest Minecolonies 1.16.5-1.0.480-ALPHA and started getting spammed with OpenGL errors at an incredibly fast rate, quickly generating massive log files. At first I attributed it to being an issue with Optifine and the latest forge version since Minecolonies 1.16.5-1.0.480-ALPHA required a forge upgrade. So I downgraded to 1.16.5-1.0.475-ALPHA and back to the forge version I was previously using (36.2.23) but the errors were still happening. Finally, downgrading to 1.16.5-1.0.474-ALPHA has stopped the errors- so it seems to be something that changed on Minecolonies' side. Something related to the Nether Miner update?

Expected Behavior

No errors.

Reproduction Steps

Upgrade minecolonies to 1.0.475 or 1.0.480.
Have optifine.
Profit?

Just to say this is still occurring with the latest version (minecolonies-1.16.5-1.0.507-BETA). And I do believe the errors are caused by the hut blocks specifically, though it is inconsistent.

I was testing with the school hut block and a level 0 or level 1 school causes openGl errors, no matter how it was placed.. normally or creatively (either paste option)- goes away soon as I destroy the school hut block. If I creatively paste a higher level (2+) school, I briefly get a flash of openGL errors but then they stop. However this does not seem to be consistent across all huts. Regardless though, it is definitely caused by the hut blocks themselves.

Definitely optifine issue

@OrionDevelopment or @Nightenom any idea.

475 added: .forEach(hut -> RenderTypeLookup.setRenderLayer(hut, renderType -> renderType.equals(RenderType.cutout()) || renderType.equals(RenderType.solid()) || renderType.equals(RenderType.translucent())));

translucent to huts because the nether hut block has this.

Was debugging issues with another mod and it was suggested to disable Optifine's "Render Regions" feature. Figured I would go ahead and try out the latest Minecolonies (1.16.5-1.0.564) and see if just maybe this helped with it as well, and to my delight it did. The OpenGL errors have now stopped with that feature turned off.
