charles derousiers 7a8788dd6f Fix material function crash with Substrate on preview. ...

There were two issues:
* The material function preview was not correctly converting material attribute output.
* The cached expression were not populated, causing the IsMaterialAttributeOutput() function to not return the correct value.

Down the line, this was causing material attribute data to be connected to a float3 input causing a crash down the line.
