    Is it possible to request a more streamlined terrain to landscape conversion? Currently exporting terrain as a datasmith is great but lacking the functionality of a landscape object. I am trying to incorporate UE into my workflow for large scale visualizations using real world survey data and it would be great if I could import graded civil 3d terrain objects into max and then export them as datasmith and have them functions as a landscape in UE4. If there is already a plan for this or I have missed another suggested workflow to accomplish this my apologies.
    Thanks

      This is on our list of "to do", just that there is a lot of stuff ahead of it. We're aware of the problem.

        I second the greggotsch request but from CityEngine end. CityEngine utilizes raster DEMs but landscape offers lot more functionality.

          Hello all,
          I work at a construction firm and have been following several companies who are getting into the VR realm. They are uploading their models into software to be able to walk the job sites and give their foreman a better understanding of what they are going to be building. My company currently uses AutoCAD MEP and Fabrication MEP, both produce dwg files and I noticed that Unreal studios doesn't support those files yet. Is there any way to get those file types available for the engine?

            Your path is probably through 3Ds max. We could consider dwg, but your version would require object enablers that only autodesk provides that we don’t have access to.

            I can be wrong it’s been a long time I was exposed to those technical aspects..

              It would be great if you could report back if you can get this happening from AutoCAD->3ds Max->Unreal

                I don't know if someone asked for this before me. In my pipeline I use an hybrid system: datasmith for architectural elements and non repetitive elements modeled in Revit and csv data reading for positioning my blueprint actors as their counterparts are in Revit for library ones (laboratory analyzers, benches, fixtures, luminaries and so on).

                For Datasmith importing it would be fine to have some kind of voxelization option for big walls, ceilings and floors. I think so to avoid 4K lighmaps for these elements that as well in many circumstances 4K doesn't give enough quality. For example, if elements bigger than a 10 meters cube are encountered, then they would be divided in so 10 meters voxels as needed, and convenient lightmapped. This is not only good for lightmapping calculations but also for distributing meshes for calculations on swarm agents in a balanced manner.

                What do you think?. I know a studio that is doing something similar in house plugin.

                  Sounds like a good idea, maybe some kind of integrated/streamlined mesh splitting within a single mesh asset to allow multiple lightmap UVs ?

                    Yes, this is the idea: to avoid too big items that need big lightmaps. It could be achieved modeling in Revit (or whatever BIM app) for balanced dimensions with this in mind, for example creating floors and ceilings in a per room basis, or walls partitioned every x meters, but this is not the way for BIM modeling. An authomatic parameterized voxelization could solve this.

                      Yes, we've recently talked about the need for this. We have a bunch of "worst case" Lightmass baking scenes we received from customers that we want to throw at the new Lightmas. If you want to provide some problematic examples, feel free.

                        Testing datasmith in 4.20 & SketchUp 2018.

                        - is it possible to add an 'export selected' option in SketchUp? I have lots of helper objects in the scene -hidden- that still all get exported to US. Lots of manual cleaning to do in US which takes quite some time.
                        - could the geometry be flattened into 1 SM object if they are in the same group? At the moment, if you have a group with several 'clusters' of geometry, each cluster of connected faces is converted into a separate SM in US. Makes the scene hierarchy rather messy.
                        - could it be smoothing is not supported at the moment?

                          I dont know but it seems like all guides and tutorials and everything require us to use 3dsmax while I do not use it nor do I want to install it just to to some basic stuff. It would be great if the UVW-nromals or whatever it does could be integrated just fine without the use of 3ds max.

                            We are continuing to work on the SketchUp workflow. You should have solutions to these coming. Not sure about smoothing, but unless that is something special, it is supported. Perhaps you should log a bug.

                              The export visible will be supported next build. Then scenes will be your workflow to decide what to export or not.

                              for smoothing I can check. Can you send us a skp model that shows the issue?

                                Hi pf_breton , thanks for the reply.
                                Great the export visible will be an option in the near future. Smoothing works after all - my mistake.

                                I have a few suggestions if I may:
                                1. could the object names in the geometries folder be the same as the object names in SketchUp and in the World Outliner? At the moment they don't match.

                                2. I added a small picture showing the issue of meshes in groups in SketchUp that get split up into separate meshes in US (imho not the expected behavior - I would already have made separate groups in SKetchUp myself if I would like them to get split up). A fix would clean up (shorten) the Oultiner graph in US a lot.
