Minecraft version

1.20

Forge version

47.2.19

FramedBlocks version

9.1.6

Describe the bug

Using a Smooth Quartz Block on a Framed Block does not render correctly when using shaders (Complementary Unbound_r5.1.1).

Screen Shot from Minecraft of Framed Panels with Smooth Quartz Block camo next to Minecraft Smooth Quartz Stairs and Smooth Quartz Slabs.

How to reproduce the bug

Use a Smooth Quartz block as camo on any Framed Block with the Complementary Unbound shader enabled.

Expected behavior

Framed Block with Smooth Quartz camo should look the same as the Minecraft versions.

Additional details

I am using the Framed Blocks mod in the ATM9 mod pack. This issue also happens when Complementary Reimagined shaders are enable but does not happen with the BSL and the MakeUp-UltraFast shaders.

Crash log

No response

After a little more testing I found that this issue only happens when "Integrated PBR+" is enabled in the shader options.

This is caused by the way the shaders detect which block is being rendered to decide which effects need to be applied. There is most likely nothing I can do about this, I'll keep it open for the time being though in case I can find a way to fix it.
