[Update News] Modern Archviz v7.9 and ExperiArch v3.3 - NeoForge [1.21.1]

Hey everyone! I hope you're feeling well and getting ready for the summer!

I've been doing a lot recently trying to understand how shaders and raytracing works and I started applying that to my mods. The results are amazing and will be the staple of the next update. I wanted to do this for years. My mod blocks were never properly shaded. GI was actually leaking through and shadows did not accumulate the way they do with vanilla blocks while my blocks were also invisible to reflections.
Well now I made a solution for it.

Before (GI passing through with no reflection capture)

After (GI properly bounces off the surface and blocks are visible in reflections)


Currently I'm working with IterationRP and will apply that to SEUS HRR 3 later. Here's a before and after., you can see how shadows accumulate now and create much more natural feel. I also did some color correction on IterationRP.

Here are some more comparisons:

I've also been really busy with Medievalism lately. Lots of interesting updates are coming and I will apply the same shader updates to that mod as well!


Thank you so much for your support as always guys and I'll see you with the next update!

It depends on the shader. This is IterationRP but my update hasn't come out yet.

Ultimate Immersion · July 13, 2026

This is just for NeoForge. Fabric does not support models of such complexity.

Hello. I downloaded the 1k resource pack for version 1.21.1 two months ago, but the `experiarch` folder was missing from it; it was missing in-game as well. I noticed the folder exists in other versions—is it intentionally excluded only in the 1.21.1 version?

U
Ultimate Immersion · July 6, 2026

Hi, no all of the folders are on my drive but you likely only followed one link. I have multiple links in my downloads and they are separated. They all work for 1.21.1.

Is this really Minecraft? This package only works for NeoForge ? :(

U
Ultimate Immersion · July 1, 2026

Yes, and currently it only works in NeoForge yes. I'm planning to do Fabric support in the future but complex models are not supported with Fabric.

which folder should i put your mods in?

U
Ultimate Immersion · June 14, 2026

It needs to go in .minecraft/mods. I suggest you use modrinth however. It has automatic install and you can just drag drop resource packs and my mods into it and all will work including all complimentary mods. See the video in my download post.

What type of pc will it time to run this

U
Ultimate Immersion · June 2, 2026

Depends on the resource pack resolution and shader. But with mid tier PC you can easily run x256.
