Ooops sry Nus, I missed that point

I'm not really sure but this may be caused by the placement texture node which is connected to the lambert used as MDS texture.

Open the hypershade, select the wacky (lambert) and then click on the "Input & Output Connections" button. There you can see the placement node "place2dTexture" appearing within the work area. I you select it, I guess the rotation factor is not the right one, ... in the attrib.mngr.

>> what could, I guess, explain that your origin file is still right, but even when you create a new plane, no matter, the placement node is set


Well, hopin' that's the right point
