I’m looking to set up a script to help more quickly iterate on getting the model into Unreal. Main issue right now is material reassignment at the other end. I’m thinking of a script that reorganizes the model hierarchy into layers based on material assignment instead so that selection in unreal i…

I have run into a problem… V6 seems to explode blocks differently than V5. When I explode my test block in V5, I get what you would expect: new layers with the materials from the blocks layers assigned: [image] However, exploding the same block in V6 I get this: [image] Clicking on the material…

Hi - Thanks for reporting, I see that here as well. I filed this as RH-57046 . -wim

Thanks Wim. I have my script basically working (in V5) One little hiccup… Is there an elegant way to test if any of an object’s parent layers are not visible? I generally have something like a “tools” layer, and then inside that I’ll have layers with reference material, cad drawings, construction…

Hi Ryan - [image] wynott: I have run into a problem… […] [It doesn’t] allow me to pick up the MaterialName from the index (and then subsequently make a new layer with the MaterialName. Could you explain in detail why this is a problem for you? Apparently possible options include: Leave …

@wim When I import into unreal engine with datasmith you end up with thousands of individual meshes that all need materials assigned. Even though the model may only use a handful of different materials overall, it takes ages to go through the model and assign materials if the hierarchy is organized…

Thanks for that background, Ryan. Is it possible for you to share your code? Perhaps there is a different way of achieving your goal. -wim

It’s really scabby and full of debugging prints and stuff… But attached. I’m having an issue where if I don’t run the functions one at a time it messes up… alternately commenting them out. UnrealMatLayers.py (4.6 KB)

Hey Ryan - Comment from Dale on that issue: For this user it sounds like have duplicate names would work AS LONG AS the materials with duplicate names are the same. I’ll comment out the new_mat.ClearName(); and see if anybody complains. Currently, we allow materials to have non-unique names and…

I haven’t bought a V6 license yet… So I don’t believe I can test a fix in V7.
