I am trying to use the Interpolate Material Instance Params node in Blueprint and it works, but some of the parameters are not being changed.
Both material instances derive from the same base material, though I believe some parameters are being optimized away?
I put a breakpoint in UMaterialInstanceDynamic::K2_InterpolateMaterialInstanceParams, and sure enough the parameters weren’t all there for one of the materials.
Can I somehow stop material parameters from being optimized away (or is this even what is going on)?
Thanks in advance
