Save Texture UV position


#1

It will be great if sketchup save texture UV position either if unchecked Use texture image in Materials editor and changed it to color


#2

forgive my ignorance: UV position?


#3

It’s like UVW Mapping in 3ds Max, the problem in sketchup when unchecked Use texture image in Materials editor and changed it to color and enter a new image the position for texture is missed for all objects.


#4

@Whaat s plugin SketchUV has a function to save the UV position an reload it after changing the texture…


#5

? I still don’t get it. (sorry)

When you place a texture onto a surface, say a square, you know the X and Y of where the texture starts. But if you also want to know where in the texture corresponds with the start point, you need the X and Y of the pixel in the texture that is used. But, as X and Y are already used for describing positions in space, U and V are used to point to the coordinates in the texture.

It gets more complicated when you start stretching and rotating, or skewing, and so a UV map would be a description of how the coordinates in the texture map to the coordinates in the model.

But doesn’t it already do that? If I rotate a texture and move it, I can sook it up with the pipette and use it (with the same rotation and transformation) on another surface. Or multiple surfaces.
