If you create an make array node with 10 index for example with random numbers and its connected to an floats array, after disconnect the make array from the other array save all and close and open back the editor the make array now don’t have class (float) and all index data are lost.
I’m not sure if that’s intended behavior, but for a work around, you could plug MakeLiteralFloat nodes into the MakeArray node. MakeLiteralFloats seem to survive the reboot without being connected.
Okay thanks.
