So now I've narrowed down my current question to the more focused question "How would I go about making a TwinMotion plugin of my own?" How to tell which packages are held back due to phased updates, Solution: Replace "bump", "map_Bump", "disp", "map_Disp" with "norm" or import with "Bump/Displacement is Normal Map" enabled. Sorry, that is a complete misunderstanding. Select this option to hide the lines wherever two surfaces come together. That's fine. Question: Why isn't my subsurface+glass+alpha material exporting with every property? At present, I'm not seeing a way to export an FBX with materials using the Revit API.

The FBX is an export of Revit model. I love Twinmotion (based on game engine and all the work is done for you, rather than stetting up unity - plus it support VR) but the FBX export pluing gives you various options on how you want to break the model down and also on how you want the materials to be exported. "matte", Solution: For every "d" option flip (newvalue = 1.0 - value) every number (or just set it to 1.0) or import with "Invert Alpha" Open the Revit model to export to FBX file format Open a 3D view. rev2023.3.3.43278.

I have found that if I link the fbx file rather than import it, SOME (80%) of the materials are now in the max file?!? (Apparently, there's a way to get the materials to re-appear if you open in 3DS Max, but that's extremely non-optimal for an automated pipeline.) 2015-2021 BIMWERX. It's just a lot more code that I would have thought. This is how the process works: We draft in Revit, export the model to SketchUp, (where it imports as a blank 3D object with no labeled materials), then we apply materials to the SketchUp model to give it color. Why is this sentence from The Great Gatsby grammatical? Apparently you can at least get the material names for objects so it's easy to batch replace materials. If you are interested in the FBX export rather than OBJ, then OF COURSE you should use the full-fledged built-in functionality provided by the Revit end user product itself. Added Decimation.
