I have been trying to figure out how to solve this problem for DAYSSSSS, without much luck. I would really appreciate some assistance if possible.
I am trying to create a really realistic interactive model of a two-family flat.
This is the house in the real world:
This is the original model in SketchUp:
Here is the model in SketchFab:
The textures on both the SketchUp and SketchFab models (as of the time this original post is being made) are seamless photo textures I made in photoshop from real world photos of the materials.
This is a photo of the brick facade on the structure:
Here you can see a comparison of the real world and modeled wooden texture on the doors:
They are decent, but ultimately insufficient because you can see the repetitions of the pattern when viewing the structure as a whole. This is particularly true of the brick. They also don’t do the best job capturing / interacting with environmental data.
With that in mind, I followed this tutorial to make a high performance endless texture in substance designer.
Here is a screenshot of that substance:
It’s not perfect, but the basic framework is exactly what I was looking for.
The problem I am now having is trying to apply the substance to the model itself.
I’ve been trying to figure out how to do this for days in the SketchUp and Allegorithmic (maker of Substance Designer and Substance Painter) forums.
I know there’s a Substance Painter exporter and that the seemingly obvious strategy would be to import the model from SketchUp into Substance Painter, import the substance from substance designer into substance painter, apply the texture/substance, and then upload to SketchFab.
Problem is that SketchUp doesn’t really process/do UV wrapping/unwrapping. There’s an extension that lets you add them, but it’s only for windows and I have a mac/it costs money/its really inefficient for complex models.
Following the advice from one of the responses and this tutorial, I imported the model into Blender to try and “smart uv unwrap” the model, which works for the most part but can only be done one group at a time.
Here you can see I was able to unwrap the UV from the brick exterior group:
But I have over 100 groups total
doing this manually one by one would take forever and certainly isn’t a solution for other models I have the same problem with.
So, with all of this in mind, what should I do? I’ve been modeling the structures in my neighborhood, which typically feature a small handful of material types and I want to have a handful of super detailed super realistic textures that I can use on the models of them that I’m creating.
I feel like I’m always seeing these amazing models in the SketchFab explore feature that make me say “wow, how the heck did they make that? It’s so realistic!”. I guess I just really wanted to see if I could create something of that caliber.
I want to create a model that lives on SketchFab that I can show people that’s better than the static renderings of proposed structures we normally see to demonstrate that 1. SketchFab is a superior architectural visualization platform 2. Interactive models are way more engaging than the paper handouts we always get at community development meetings.
