i mean i was just switching out parameters.. it was visible.. but now even if i create a new parameter and try to connect it … it dont show..
Original problem was packed level actor custom primitive data related…I have a switch to use the parameter as is or to use CPD… but the CPD worked in a level instance.. but didnt work in packed level actor… Then the parameter itself was unable to be changed… Like u can see the material instance change its viewer.. but not in the scene.. for the texture array…
but the material just got worse with the parameter not being visible at all in the material instance options..
Ill try to recreate it a little later.. copy and paste everything. This thing is just gotten worse and worse… tried deleting all the unused directories of the project.. like intermediate and all that… but that didnt help.
