Devin Johnston Posted January 12, 2016 Share Posted January 12, 2016 I don't have that much experience with Revit models, since FBX linking is totally broken in Max 2016 I'm using the Revit linking. I'm working on a linked Revit file and I'm having some problems with some of the geometry, as you can see from the image the window & door frames are messed up. The frame has a Vray material applied to it, I've tried clearing UVW mapping and flipping & unifying normal with no change. I'm using Vray 3.20.03 and haven't had any problems like this so far. Any idea what's causing this or how to fix it? Link to comment Share on other sites More sharing options...
brendanrogers Posted January 12, 2016 Share Posted January 12, 2016 Try importing the FBX model and see if its still happening. Link to comment Share on other sites More sharing options...
Devin Johnston Posted January 12, 2016 Author Share Posted January 12, 2016 I only have the Revit file and I don't have Revit. Link to comment Share on other sites More sharing options...
Scott Schroeder Posted January 12, 2016 Share Posted January 12, 2016 Co-Planar? Revit doors and windows can be particularly nasty with 10 doors on top of each other. Add an edit mesh/poly on the door and start deleting elements. Link to comment Share on other sites More sharing options...
Corey Beaulieu Posted January 13, 2016 Share Posted January 13, 2016 I just had this same problem with doors made n Revit today.... my fix was to grab each element of the door, move it away from the other pieces of the model, and then weld verts and cap any holes. Then I would move it back. I moved it away because the door, frame, glass, and transom were all merged down into one piece of geometry. I also had imported the model as FBX/DWG. I don't know if this will work for you, but it solved my problem. Link to comment Share on other sites More sharing options...

Chris MacDonald Posted January 13, 2016 Share Posted January 13, 2016 Ahhh, the wonders of Revit. Try resetting the xform on it, sometimes individual blocks get re-scaled on import and crazy stuff happens. Save your scene first though, because it's so unpredictable.

Thanks for the suggestion but it didn't seem to make a difference. Link to comment Share on other sites More sharing options...
Scott Schroeder Posted January 13, 2016 Share Posted January 13, 2016 What if you render a gray material override on it? Maybe it's a map issue on the metal material? Is this the revit material? Revit loves real world coordinates, set at feet. So anything else could be causing weird mapping issues. Link to comment Share on other sites More sharing options...
Devin Johnston Posted January 13, 2016 Author Share Posted January 13, 2016 A map override reveals the same issue, I replaced all the Revit materials with Vray materials anyway so that's not the problem. My units are set to inches and when I look at the geometry up close nothing looks out of whack. After talking to my BIM manager he informed me we got this model from another firm and that it's full of problems. IDK what that means exactly but hopefully it's just this model that's screwed up.

brendanrogers Posted January 13, 2016 Share Posted January 13, 2016 export the problem objects out as .fbx and re-import them and reset x-form, convert to edit mesh etc. Link to comment Share on other sites More sharing options...
branorataj Posted February 10, 2016 Share Posted February 10, 2016 what worked for me was selecting the object converting to editable poly and than just grabbing the particular object (i have selected to group by revit material) and detaching from the rest. suddenly it renders fine.

branorataj Posted February 10, 2016 Share Posted February 10, 2016 had this very same issue. what worked for me was selecting the object, this selected all the windows in scene as i had them grouped by material, then converting to editable poly and detaching the window. once you detach from the rest it suddenly renders fine.

Devin Johnston Posted February 12, 2016 Author Share Posted February 12, 2016 I'll try that next time, thanks Link to comment Share on other sites More sharing options...
