Hi, nice model,
some big textures, but overall it’s not that big, especially considering the size of it (several buildings, with details and furnitures, 90mb is not shocking)
if you absolutely need to reduce weight, you can use Material Resizer (a free extension), but I’m not sure it’s your main problem here
but you have a lot of trash tags.
my guess is you didn’t use tags, you have the tags of all the things you downloaded (various languages and symbols).
and your over-nesting might be a result of it.
right now you have a group that contains most of the project, then a sub group that contains all of the furnitures of one room, then a subgroup…
you could use tags. Create a tag fro the walls and floors, another one for the doors and windows, another one for the roofs… and place the different groups on them.
looking at your outliner panel, you used it the way you should use tags.
you have one massive group with all of the buildings, then subgroups, then then then (it goes 6+ nested levels)
you have another group with all the tables / chairs / dining stuff, it could be a tag aswell. same for the logos
Apparently Lumion doesn’t like that, because it means going really deep to reach the material infos.
In addition to de-nesting your file, using tags would allow you to quickly turn off part of your model.
there are no right way to organise your tags, if your project was mine, I would do this :
- a tag folder for each building. ← this is extra, it allows you to manage each building separately.
- in each tag folder, a tag for the floors, another for the walls, another for the roofs, one for the doors/windows, and one for the stairs.
- then, one for the decoration, and if you have some, one for the vegetation
- finally, one for the logo on the building, and one for the rest (the bits that don’t fit anywhere)
It may feel a lot, but I usually do this while modelling. I make the walls and floors, and tag them, then I make the doors and windows and tag them…

this is the tag structure of this file. you see most of the groups / components are directly accessible, pretty much nothing’s nested, and most of them are not even named. but thanks to the tags and tag folders, I can control the visibility.
at this point, In your place, I would take a couple hours off for some cleaning :
- copy your file. just in case
- delete all the tags. unless you have some you made yourself.
- explode your groups. not ALL the groups, keep the ones that define objects (check my file to see what I mean)
- create your tags
- turn off your tags. trust me
- now select the groups and components, in the entity info panel, assign a tag. they’ll dessaper, because tags are hidden. meaning the remaining things on screen are untagged.
- keep going until you have pretty much nothing left on your screen. it means it’s all ordered into your tags. you can turn your tags on again.
