So this UnReal methodology is nice but also not nice.
As a noob, I appreciate that this SketchUp/Datasmith/UnReal methodology simplified my workflow and time required to achieve a final output. However, I’m busy with some UnReal Online Learning Courses which refers to and uses the Graph Panel in the Material Editor. I would like to upskill myself by getting into more of the detail and power of UE. The instructor in this paricular course uses 3D Max/Datasmith/UnReal workflow and (ostensibly) has the Graph Panel available as soon as he opens the Material Editor. Like the noob that I am I was clicking around trying to find a toolbar menu whereby I can activate the Graph Panel on my side. If I hadn’t come across this thread regarding the SketchUp/Datasmith/UnReal workflow I would still be searching online and randomly clicking everywhere.
The solution offered above of creating a New SketchUpMaster could work (I presume - I couldn’t find the copy I saved when re-directing the Parent material).
The second option, of course, is to simply create each of the SketchUp materials afresh inside UnReal. Quite a pain if one has many materials.
So why is that the 3d Max/Datasmith/UE automatically allows each material to be independently modified but the SketchUp workflow doesn’t?
