What is the Kappa Shader?

A Minecraft shaderpack that aims towards a realistic, but also authentic look. So it is not plainly using physically accurate vales and equations like many other packs do. Instead, while still using many accurate calculations, it is tweaked to reproduce what you could observe in nature, which usually goes beyond just having equations to describe most phenomenons.

Kappa Shader v2.0 Lite

This is the first version of Kappa Lite.
I decided to publish it as a public Release Candidate to bridge the time until I am done updating the regular Kappa version.
That may take some time since I also want to update some of my other projects before that (eg. Vanilla Plus).

It’s kinda silent atm isn’t it?

If you are not accidentally peeking at my discord server you might be wondering why there is an absence of updates lately. Lemme explain this here. I have recently started a collaborational Project with Lee, another shader developer, and we have been doing some kind of power run to a 75% feature complete state on overworld over the last few weeks. As you can imagine this was taking up the […]
