Have you tried my most recent terraced, detached and semi-detached houses? I specifically created them with no third party props to reduce such issues. Check them out. http://steamcommunity.com/profiles/76561198025130003/myworkshopfiles/

They're better than the originals also.

I love your UK collection, but there are so many props... No way I can run it.

Missing asserts

@Macwelshman, did you ensure that your LOD uv's are all within the 0,1 bounds? If you stretch those UV's outside the bounds as you are allowed to do with a regular texture, you could get some weird things. I believe the game creates a massive "texture atlas" of all the mods you use in the game and when those UV's get stretched beyond that bounds they sometimes take on other properties as you could see. Either way - the issue seems to be directly related to the UV unwrap and the specular mapping you've assigned to the model. I know you're an excellent modeler and may have tried all these tips but just figured I'd throw them out there in case they are something you haven't tried yet.

It is quite weird indeed...
Perhaps, Rik4000 who creates nice UK buildings too, could look at it...
Now, when all the houses are close to each other like on the pic, we do not see it that much.
We have to go for a close look to notice it.
That will be fine...
Thanks for your explanations...

I have tried everything to solve this garage problem and have failed. The latest updates still have weird stuff happening. They used to go green or purple at narrow angles (see pics https://www.dropbox.com/s/dpxiowcglixdtzs/garage%20purple%201.png?dl=0 and https://www.dropbox.com/s/2nwvkkku85dsbud/garage%20purple%202.png?dl=0) but now they go yellow and black stripes (see pic https://www.dropbox.com/s/3q1dmvahts672nm/garage%20yellow%201.png?dl=0) .

I've tried everything: new textures, new lods new models.

If someone else can help with this it would be great as I've had enough. They'll just have to do.

Very nice ! I'm glad you aware of it..I'll keep watching...

Thanks! I am aware of the garage issue and have been trying to solve the issue for a while now. Just trying a new one now. Watch this space.

Allow me to let you know that the garage does not look quite right regarding the texture.
When we turn around the house, in the game or even in the asset editor, the walls and the roof come with a glassy aspect. It's like they are made of glass.
Otherwise, it is great to build nice neighbourhoods with these buildings...

Love your stuff man
