Oculus in All the Mods - Gravitas

Oculus is an unofficial fork of Iris that is made to work with FML, which is what lets Iris-style shader support run on a Forge-based pack like this one. If you want shaders in your modded world, this is the mod that provides them.^[1]

The pack ships Oculus 1.6.4, built for Minecraft 1.18.2.^[2]

What it aims to do

• Performance: Oculus should fully use your graphics card when it is paired with optimization mods like Rubidium.^[1]
• Mod compatibility: it makes a best effort to work in modded environments, which matters in a big pack like this.^[1]
• Backwards compatibility: existing ShadersMod and OptiFine shader packs should just work, with no changes to the shader pack.^[1]
• A well-organized codebase, so working with the code is a pleasant experience.^[1]

Who it is for

It is for anyone who wants better visuals through shader packs, including your existing ShadersMod or OptiFine ones. If you only care about frame rate, Oculus is meant to be used alongside an optimization mod like Rubidium rather than as a replacement for it.^[1]

Unverified The sources I have don't show any quests, guidebook entries or progression role for Oculus in this pack, so I can't say where it fits in the progression or on the ATM Star path.

Oculus is a bit different from most mods you'll meet in this pack. It's an unofficial fork of Iris, made to work with FML, and it's all about running shader packs. That means there's nothing to craft first and no quest to chase.^[1]

I checked, and no recipes in this pack produce Oculus items. No quests involve it either. So there's no recipe to show you here, and your first steps are about setup, not progression.^[1]

What to know first

• Oculus is meant to make full use of your graphics card when it's paired with optimization mods like Rubidium.^[1]
• It aims to be as compatible as it can with modded environments, which matters in a big pack like this one.^[1]
• Existing ShadersMod and OptiFine shader packs are meant to work without any changes, so you can bring a shader pack you already like.^[1]

What I can't confirm

Unverified The sources I have don't cover where to put shader packs, which key opens the shader menu, or which shader settings suit this pack. I'm leaving those out rather than guessing.

This section is short on purpose. The project page describes Oculus as an unofficial fork of Iris, made to work with FML. It talks about performance, compatibility and shader pack support, and says nothing about machines, multiblocks, power, fluids or item automation.^[1]

What Oculus is designed to do

The project page lists these goals for the mod:^[1]

• Performance: Oculus should fully utilize your graphics card when paired with optimization mods like Rubidium.^[1]
• Mod compatibility: it should make a best effort to be compatible with modded environments.^[1]
• Backwards compatibility: all existing ShadersMod and OptiFine shader packs should just work, without any modifications required.^[1]
• A well-organized codebase, so that working with the code is a pleasant experience overall.^[1]

Unverified The sources here include no config files for Oculus in this pack, so any Oculus settings or pack-specific changes to the mod are not shown here.

Gravitas 4.0 ships Oculus 1.6.4 (the file oculus-mc1.18.2-1.6.4.jar). Oculus has been in the pack since Gravitas 1.1 or earlier, so you've had it for a long time. These are the notable changes from the mod's own changelogs, oldest first.^[2]

Notable releases

• 1.2.5a: fixed some crashes related to Tesselating/Vertex things.^[3]
• 1.5.2: full support for the majority of Optifine shaders, plus some bug and crash fixes.^[4]
• 1.6.4: includes all the Iris changes from 1.6 to 1.6.4, plus a set of Forge specific fixes (listed below).^[5]

What 1.6.4 changed on Forge

• Block lighting is now on par with Forge.^[5]
• Added compatibility with Reforgium.^[5]
• Removed the NotEnoughCrashes warning screen. Only a notice in the crash report is left.^[5]
• Restored block lighting on 1.19.2 (SEUS PTGI and similar shaders). The pack runs on 1.18.2 going by the jar name, so this particular fix is listed for a different Minecraft version.^[2][5]
• Jar naming now matches Iris.^[5]
