Uv mapping question

[dmoyes]

Can someone explain the circled message? I’ve been having weird mapping issues such as the wood grain in one side of a box rotated 90 degrees. See 2nd image. I’m using V6.

[pascal (Pascal Golay)]

Hello - if a texture uses WCS (world coordinate system) then it has its own ‘real world’ size and orientation and will not pay attention to individual objects’ UV or repeat values. - this is useful for textures like bricks where you want them to be a specific size, not a repeat number.

Thanks Pascal. I also found another useful response here:

Texture Mapping Seems Locked?

Applying some materials from the library, then wanting to use Texture Mapping to adjust size, surface type etc, no change to mapping or size if I try to adjust ? There is a small window saying ‘some of the materials are using WCS and changing the values below may not change their values’, is there a way to get back to being able to change them as I usually do ? tia [Screenshot 2020-04-07 at 23.09.25]
