Chameleon Post Process

I’ve been creating Vulkan-exclusive builds (testing) and only Chameleon materials/BPs do not compile.

Warning: Failed to compile Material /Game/Chameleon/Materials/M_2DTransform.M_2DTransform for platform SF_VULKAN_SM5, Default Material will be used in game.

The only errors/warnings I get regarding the materials (each of them, same thing).
