Rendering issue

I am trying to texture a house. Let’s say, I saw, that the roof could be better, if it had angle. I move the edge up, but the mapping doesn’t fit to it (fits only after apply) and the new roof appears invisible. So I can’t follow the change of textures on it. Is any way to fix this?

Maybe you can share the file for further investigation.

I put the texture, then I wanted to change the “angle roof” into “flat roof” by moving the edge down. As you see, the yellow lines show the change in model, but texture doesn’t get changed until I press Apply. So I can’t follow how UV mapping will change after I edit model. It’s the same with face moving, boolean operations, all changes in model.

I suppose for now don’t edit your object while you are using _UVEditor. If you find you need to edit your model first apply the uv map, make your object change and rerund _UVEditor.

@Jussi_Aaltonen am I correct in assuming that the UV Editor currently doesn’t know when the object being mapped has changed while it is active?

One cool thing I found is you can explode the uv mesh in the uv editor grab what you want join that together and rotate or scale that. That’s really nice when you need to rotate, scale or move only a part of the UV mesh that was previously joined to another part but don’t want to exit the editor.

As soon as UVEditor is started Rhino creates a custom mapping primitive from the current object and draws that instead of the object geometry itself - only wires are according to the object geometry. Modifications to geometry never change the custom mapping primitive.

Instead of modifying the object while UVEditor is open it is recommended to modify the geometry first and only then start UVEditor to tweak the UV’s if needed.
