Site split into sections and assigned materials, but showing up as one grouped surface in lumion

[Anonymous]

Hello, I have been banging my head against the wall for almost a week, trying desperately to get a model where the specific site and topography is essential into lumion. I have assigned each split up chunk of the surface different materials, but they all show up as one site in lumion. How can I bring it in so that I can assign each one of my site chunks a different material in lumion? Any help would be much appreciated.

try changing assets of materials

I'm not super familiar with Lumion, but when you were creating the different materials, if you right clicked on the material name on the left side and pressed duplicate, Revit didn't duplicate the material in the way that you think. If you look at your material and the number that is circled below is not "0" this might be your issue. Click the duplicate button on the right, circled below. I typically just create new materials from scratch to avoid this with the button in the bottom left that looks like a sphere with a + symbol on it.

Hello, thank you for your response, I am quite familiar with Revit and know not to just duplicate materials. I actually went into the material editor and found either asphalt, grass, etc. and made a new material from scratch for each, so it's not just a duplicated material or material group. That's why I am so confused, I have never had a problem with this when going from revit to lumion.

What do you think I should change? Identity, Appearance, or Graphics? And if I created each material from scratch and assigned it, how would that change anything as far as the file itself reading differently in Lumion? I feel like it's got something to do with the topography being one type of element, and also lumion is reading layers even though Revit functions more on views than layers, so each layer is identical..... As far as troubleshooting, I have tried looking at the lumion settings but they're rather stupid and I can't seem to find anything of actual use in there in terms of how files import (to resolve the layer issue). I have tried exporting the Revit files as an FBX, as a DWG, and I have messed with all of those export settings available in that exporting process to see if that would work. Live sync for revit to lumion freezes and crashes my laptop (an ASUS StudioBook Pro), so I haven't tried that, but know it wont work. Let me know if assets changes will still help, and which to change 🙂 Thank you for your response.

All of the mateerials on the site look like this, so I think we should be good on the assets part

I'm  thinking  this issue is related to the View Phase Filter.  Set to "Show Complete" and report back.

@barthbradleyI tried changing the phase filter from "show all" to "show complete", but these images are showing what's happening in Lumion. It's absolutely maddening because the surface shows the suggestion of perforation/the sections of the site, but in material editor, it still reads as one big surface. UHG I am so confused.  

[ryley.g.h]

can you copy a chunk off to the side and see if Lumion is still trying to lump it all together?

[Anonymous]

@ryley.g.h that's just the problem, sure I can copy another model right next to the other, but it doesn't import in chunks, it imports as one large surface, neither split like in revit nor editable as different materials as assigned in Revit. I am not sure what that's going to do for me

[barthbradley]

I don't think this is related to materials.  Looks like it's related to phasing graphic overrides.  Post a screenshot of your "Show Complete" Phasing Graphic Overrides settings.

here's that setting for you @barthbradley

[Anonymous]

@barthbradley each of the topography chunks (split, not subregion) is in the new construction phase individually

[Anonymous]

here are the visibility graphics settings for the topography as well in case that helps

Is it possible that this is a problem on the lumion side of things? Do you have an older project from Revit that you know worked which you can just quickly try?

[Anonymous]

Here's an example of a project that I did where we had the semester to put all of our projects on the same site. I burried most of mine into the ground and needed to split the site into water, a path, and grass. This worked just fine as you can see in the final rendered images. I have also shown a couple of interior renders that used the same principal. I split the floor piece into different chunks, set the heights I wanted, and assigned them materials in lumion, and it worked just fine. While the file I'm working on now might be slightly bigger, it certainly has worked for me in the past.

Are you able to grab that old Revit file, and insert it into a new Lumion file and still do the same thing with the split surfaces? Trying to see if a software update has screwed something up.

Looks pretty cool by the way!

1. Is the question how to import the model into Lumion WITH THE ASSIGNED Revit material or is it how to apply Lumion material on the Toposurface?
2. Are the surfaces selectable in Lumion? or the surfaces all got merged back to into one?
3. Are you using the latest Lumion Exporter plugin? are you using LiveSync or are you exporting manually?
4. Is the site Linked? or both building and site in the same model?
5. What are the import settings, can u share a snapshot?

[Anonymous]

I can try that and see, and thank you 🙂

Hello @RDAOU, thank you for joining! To answer your questions 

1. Yes, in a way it is about that. However, it's not just the materials that aren't transferring over, I am also struggling because the site chunks (a topography I split into various pieces, not sub regions) are not showing up as separate either. Neither the chunks or their individual materials are showing up. Hopefully that makes sense
2. They are unfortunately reading as one surface in lumion, but they aren't one surface in revit.
3. I am exporting manually because Live Sync crashes my device (because its a laptop and just doesn't have the horsepower for live sync). When exporting I have saved as both an FBX file as well as a DWG.
4. The site is not linked, I imported the surface from the GeoLocation function on Sketchup and used the "toposurface" button in the Massing & Site tab. I then used the "create surface from import" selection, and hid, and then eventually deleted the original import that the topo was created from. 
5. The import settings looked like this:
