Create Mod chain conveyors not rendering using stock Complementary Unbound

Hey, I originally asked this question on Complementary Discord because I thought that was the right place. But then I was referred here. I have the following problem: As you can see in the screenshots, everything is covered by Create, except for the chain conveyors when I use Complementary Stock (or Euphoria). The same problem does not occur with Rethinking Voxels. I am using the following: Minecraft 1.21.1 Neoforge 21.1.174 Sodium 0.6.13 Iris 1.8.12 Create Mod 6.0.6 Any ideas?
