How to import from revit to UE4?
I'm an architect and I'm interested in using UE4 to create walkthroughs and videos. I have watched all the tutorials and read some more, but there is no tutorial as on importing from revit. I exported fbx file from revit but when I import it on UE4 either all the pieces of the project, in this case a house, are all separated, or all stacked together in one mesh, also there are no materials imported and the scale is off, so my question is if there is a workflow that i should follow to be able to import correctly my models to UE4.
Thanks a lot , I hope there is someone here that has come to a solution to this.

I know you sent me a PM with this, but for the sake of helping others as well I'm posting your questions here with follow up answers. :)
The reason you're getting UV overlapping is a couple of reasons. The biggest reason is that the UV channel is being used as the lightmap (where shadow information gets backed for static meshes). If you're materials are looking OK you can make your Directional Light and any other Movable which will make them dynamic and not need to bake any shadow information.
If you want crisp shadows that are baked and provide zero overhead during run-time you'll need to created a second UV that can be used as a lightmap. The key here is that any mesh geometry must stay within the 0,1 UV grid space.
I've not used Revit before, but I know it doesn't really use any convential UV setups.
I've suggested in the past for those who don't have access to UV tools in their programs to use Roadkill UV because it's easy enough to use, there are tutorials to get started, and it's FREE! (Link Here) Video Tutorial to get started.
If you're only concerned with doing something as a visualization and not focusing necessarily on game play then using Dynamic lighting may be your best bet, at least with getting started. This will negate the need for lightmaps and a second UV that is causing the Overlapping faces warning you're seeing.
There are quite a few ArchViz guys on the forums doing some really cool stuff that could probably give you some pointers more so than me.
Here are the users and their Forum WIP posts:
This one is especially interesting in that he has done a lot with Blueprints and interaction with the scene:
I hope this all helps. I know it's a lot and if you have any questions feel free to post here and I'll help out where I can! :)

Hi Julio Arco,
You may have read through this already, but if not here are the documentation links for our FBX pipeline:
The biggest take away from the above would be the following:
If you have any questions feel free to ask.

you can use revit export to twinmotion plug

You can use twinmotion's revit plugin. It works well.

i think i´m having some problems, importing the meshes, with the uvwmap, because: I set cm in revit and export it to 3ds max in cm, but when i assign the uvmap i set box type, in this step i have a question: Do i have to set 100cm i the 3 values??, because when i set this, the "box" of the uvwmap is really big more than the meshes
