How do I get the UVs right for this?

NullPointer · Mar 2018

Hi!
I have been working on a house model for UE4, and I have been struggling with this for a long time.
What I want to do is to add indiviually modelled roof tiles along the edges, like in this model: (inspired from: https://80.lv/articles/romanian-village-production-in-ue4/ )

And I don't really know how to get the tiles perfectly aligned with the texture and how to connect the UVs of the tiles to the UV of the roof. Or is it better to add them in UE after finished with the texturing (substance)?
Thanks!

What tool are you modeling & UVing with?

Make the tiling texture first, apply to the roof, model 1 edge tile, UV it to match the roof. Then duplicate it and offset each UV for uniqueness.

I'm modelling with 3ds Max and ZBrush, and making the UVs with Headus UVLayout. How do I offset the UVs to match the texture exactly? Do I have to do it one-by-one?

Bring the UVs back into 3ds Max, apply the texture to the model so it shows in the viewport, and apply a UVW Unwrap modifier to edit the UVs. This will let you see the 3d model while you edit the UVs.

Thank you! I overcomplicated this a bit.

Haha, I understand. Easy to do when you see a neat little hack like this!
