what shader? is it the latest version?

tunaflsh•5d ago

photon shader from modrinth

Puhpine•5d ago

latest version?

tunaflsh•5d ago

but I've seen the github version might be more up to date

Puhpine•5d ago

the modrinth version should work fine what DH version? and have you tested with just DH, iris and dependencies?

tunaflsh•5d ago

oh it was version 1.0a is 1.0 better?

Miki_P98•5d ago

Depends, 1.0a can mean either: - Alpha (1.0 is newer) - Patch „A” (newer with some bugfix)

tunaflsh•5d ago

I'll test now with just DH and Iris ok so I could not replicate the error with just DH and Iris. this might be mod incompatibility I'll try to pinpoint

Puhpine•5d ago

alright

I was wrong. I can replicate it. With just the following mods: - sodium-fabric-0.6.0-beta.2+mc1.21.1.jar - iris-fabric-1.8.0-beta.4+mc1.21.1.jar - DistantHorizons-2.2.1-a-1.21.1-neo-fabric.jar - authme-8.0.0+1.21.jar The steps to replicate: 1. Launch Minecraft 2. Disable DH rendering and shaderpacks 3. Relaunch Minecraft 4. Join a server/start a world 5. Inside the world enable DH, then enable shaders 6. Get the error message

dh_terrain.fsh: dh_terrain.fsh: 0(364) : error C1503: undefined variable "dhProjection"
0(365) : error C1503: undefined variable "dhProjectionInverse"

dh_terrain.fsh: dh_terrain.fsh: 0(364) : error C1503: undefined variable "dhProjection"
0(365) : error C1503: undefined variable "dhProjectionInverse"

Minecraft version: 1.21 Fabric loader: 0.16.5-1.21 One way to work around this I found was, to repeatedly disable/enable DH and/or shaders. Or a better way is to enable both despite the error message then relaunch the game and both will load fine. Also it seems like a different set of variables are undefined each time.

Have you tried a different compatible shader? Oh https://discord.com/channels/881614130614767666/881614131877269586/1296608690442469418
