Revit has a direct FBX export functionality, but unless the FBX is opened in 3ds Max, materials will not import. This should be a more rare use case for Last year, we discussed analysing the FBX files exported by Revit to access the texture data UV coordinates and other material and rendering information. Revit generates the FBX file and places it in the target location. only supports "m" which stands for the term used in compositing My complete (intended) statement should read: Now that we have a 3D custom exporter at our disposal, it is easier and more effective to use that to implement OBJ export rather than traversing the entire database, reading the geometry from each element, and trying to interpret how it should be represented in a specific view. fbx) file is a format used to exchange 3D geometry and animation data. I then imported it into Unreal Engine 4 and it didn't import any textures; I clicked the Upload Textures option in Unreal Engine. @Duarte Farrajota Ramos there are countless export scripts that export blender meshes with their assigned materials, @phil123 You should post that as an answer below, with links to said scripts and a description of the workflow used, along with some screenshots of the results.

Have in mind that pre Blender 2.8# most Blender exporters do not even support Cycles node based materials at all, so even image textures used in Cycles node trees are often not expected to export correctly. Save presets into reusable libraries when available, to reduce the amount of repetition. Materials that are supposed to be shiny are diffuse and vice versa: Solution: For every "Ns" flip the value (newvalue = 1000.0 - value) or import with "Invert Specular Exponent" enabled, Explanation: The specification defines "Ns" to be the specular exponent, 0 is diffuse, 1000 is shiny (blender stops at 900). or is it really revit -> 3ds max -> All times are GMT.
