With Complimentary shaders (Reimagined) enabled, moving parts of Create buildings do not render, and occasionally create very large graphical errors. This is only the case with this mod enabled, and with these shaders. Disabling real-time shadows does not resolve the issue:

Iris-Flywheel-Compat disabled

Iris-Flywheel-Compat enabled

-MC Ver. 1.18.2
-Latest mod ver.

Currently having similar problems, so here is some more info:

• Happens with every shaderpack I tried (BSL, Complementary Reimagined, Bliss, MakeUp - Ultra Fast)
• Does not happen when shaders are disabled. If I'm understanding this correctly, flywheel optimizations are turned on when shaders are disabled, so it does not seem to be a fundamental problem in flywheel (I currently don't know how to turn flywheel stuff on, off or check their status, since it seems to be integrated into create itself. Therefore I can currently only speculate about flywheels status)
• When iris-flw-compat is disabled, no rendering problems occur while using shaders (but the performance obviously tanks considerably)
• My setup:
  • Mods: create astral with fabric 14.x via curse
  • iris-flw-compat 0.2.0
  • GPU: AMD Radeon RX 6900 XT
  • GPU Driver: radv Mesa 24.0.2-manjaro1.1
  • OS: manjaro
• My friends using Windows and Nvida cards don't have this problem. Therefore I assume that it is either exclusive to AMD cards or maybe only to AMD cards in combination with Linux mesa drivers. Update: I tried it on Windows, there the problems don't occur for me
• Cogwheels, waterwheels and co render correctly for me. Only blocks moved by the bearing block or the rope block (and probably everything else from create that turns normal blocks movable) don't render. In contrast, @Sneumorin seems to suffer from rendering problems for all moving create entities. I also never encountered other graphical glitches like depicted in picture three.

Update for clarification in my original issue, as well as a few things @SebastianMeinberger reminded me of:

• Machine specs:
  Nvidia GTX 1060 - GPU
  Intel Core i5 8400 - CPU
  Windows 10 64-bit - OS

• Issue still persists over other versions of this mod, as well as with Embeddium installed.

• Issue persists while switched to multiple shader packs listed on the mod's page as "compatible"

I can confirm as I have similar issues. Moving parts do not render and I see graphical issues all over the screen.

• Shaderpack: Complementary Reimagined
• Specs:
  GPU - Nvidia RTX 3060 Ti
  CPU - AMD Ryzen 5 5600
  OS - Windows 11 64-bit

I've got this issue as well. Using latest Iris Flywheel Compat version from CurseForge (not the outdated version from Modrinth):

• Fabric 1.20.1
• iris-flywheel-compat-1.20.1-0.2.4
• iris-mc1.20.1-1.6.17
• create-fabric-0.5.1-f-build.1417+mc1.20.1

Disabling EuphoriaPatcher-0.3.0-fabric.jar or switching to a non-EuphoriaPatches enabled Shader solved this issue for me.

Setting Shadow Sample Quality to Very Low fixed this for me.

I had this issue while using Emeddium on 1.19.2. However I've since switched to Rubidium and Rubidium Extras, which fixed most issues I had with create rendering and allowed me to use this mod with a huge performance boost.

Tested on a Mac Studio, same issue, disabling this mod fixes the rendering of contraptions that are invisible with this mod enabled

Same issue with #89, which is fixed by commit 3d07f64.
