Hi, I ran into this issue on the Answerhub here: PerInstanceCustomData not working for HISM in standalone mode and packaged project - UE4 AnswerHub (unrealengine.com)
…and I wasn’t able to fix the issue by following the answer instructions.
You need to have the HISM component created in c++ (let’s say its called “HISM_Comp”). Then, after setting custom data value on all the required instances, you need to call BuildTreeIfOutdated function
I created a C++ component as a child of
NumCustomDataFloats = 1, then called
BuildTreeIfOutdated in the constructor, but that stops it from even working in the editor.
What am I missing here? It’s so frustrating that it otherwise works fine but I can’t package it!
