Minecraft Version

1.18.x

Version

1.100.5

Details

Can see the sky and part of the world through the monitor with BSL-based shaders.
VBO option is enabled in config.

ComplementaryShaders v4.4

BSL v8.1.02.2

Solution for BSL

• Change Fast Render option to False in Video Settings > Performance.

But...

Complementary still has some problems - the sky see through the borders.

ComplementaryShaders v4.4

I'm afraid shaders are not supported by CC:T. Rendering issues are hard to debug at the best of times, and adding adding shaders and Optifine into the mix makes things basically impossible to debug, especially due to their closed-source nature.

I've spent a lot of hours trying to fix issues with shaders in the past, and it rarely comes to anything. I'm afraid I just can't justify any more time on this sort of stuff.

change monitor_renderer = "BEST" to monitor_renderer = "VBO" in Minecraft\Instances[pack you're playing]\config
computercraft-client.toml

I am using complimentary shaders and this worked for me.

CC:Tweaked is maybe conflicting with the BSL/Optifine "pipeline"
