Texture behaviour

suSteve

Hi,

If I have a cube that is cut in half with edges and I texture on half in brick and the other in carpet.

I take my eraser tool and remove an edge on one side and then remove an edge on the top the textures behave differently. For example the one on the front gets the carpet whilst the one on the top gets the brick.

Is there a reason this happens?

thanks

Could you post the SKP?

If I draw a box similar to yours with a line dividing a face and erase the dividing line, the entire face gets painted with the last material I applied to one of the faces. If I erase an edge along the top, I lose the two faces that share the edge. Both are expected behaviors.

Thanks Dave,

not a big issue but curious as to why I am getting this behaviour.

.skp attached.

Erase the edge in the middle at the front and you get carpet, erase the edge on the top and you get carpet and erase the edge at the back and you get brick.

carpet was applied first and brick applied afterwards

I believe it is related to how the faces are created and their orientation to the global axis.
If you redraw the line you are erasing from the other direction you will get the other texture.
Draw a face and copy it, split one with a line front to back and the other with a line back to front, colour left face of both red and right face green, remove the splits and one will be red and the other green.
I'm sure someone like Tig can explain the mathematics of how the model decides the orientation of the faces, but it's way beyond me.

Thanks Box, that is exactly right. It depends on which way you draw the line.
