Random bugfixes

Added "Tab" key swap functionality to all 1500+ elements in my mod for faster building

MANUAL INSTALLATION INSTRUCTIONS (Not Recommended)

(Use Auto Installer Above If Unsure)

1. Mod File Installation:

Download Modern Archviz and ExperiArch 1.21.1 here

Go to "mods" folder in ".minecraft" folder and drop both ".jar" files there

You can find it in .minecraft folder by pressing Windows Key + R and entering %appdata%

If "mods" folder in ".minecraft/..."doesn't exist, create it

2. NeoForge Installation:

Download and install NeoForge for 1.21.1

After installation your Minecraft Launcher should look like this. If not edit installations above and create NeoForge instance as seen below

Make sure you allocate more RAM, at least 16G (that should be enough even for full x2048 now)

3. Sodium and Iris Installation:

Download Sodium for NeoForge 1.21.1 and drag&drop it into "mods folder

Download Iris for NeoForge 1.21.1 and drag&drop it into "mods folder

Note that if versions are not exact as in the screenshot below it may crash on launch!

How "mods" folder should look like:

You can find it in .minecraft folder by pressing Windows Key + R and entering %appdata%

4. Resource Pack Load Order and Installation:

Drag&drop resourcepacks to .minecraft/resourcepacks folder

5. In-game settings:

6. Continuity mod installation for CTM:

Connected Textures (CTM) require another mod called Continuity and two dependency mods that ensure compatibility

Download Continuity - NeoForge 1.21.1

Download Forgified Fabric API - NeoForge 1.21.1

Download Sinytra Connector - NeoForge 1.21.1

Place all 3 .jar files into the "mods" folder along with the rest of the mods

7. Custom Emissive and Glass blocks:

To fix watery glass and non-emissive lights do the following:

In order to get mod lights and glass to work properly you need to download "Emissive & Glass Files" for SEUS PTGI or HRR shaders.

Just replace new files within SEUS PTGI or HRR (visual instructions on Google Drive)

How glass works now:

How to place ExperiArch beds:

My resource packs and mods are working best with latest Ray Tracing SEUS shader by Sonic Ether

For best visual results use HRR 3. Make sure you put Geometry Ray Tracing to 0 in HRR shader settings to remove black shadows!
