ol i saw this red lines on bottom left
so that what it does!
but this means that ounce the UV image has been change you loose the original data
unless there is a way to re upload the file from folder
may be it can be use
thinking might be possible to simulate the moon’s phases with this and use only one image!
but if need to change the day for moon’s phase then have to reload the original pic and modify it again
the image we have has something like 614 X 614 pixel about 500 KB
so hopefully it should do it inside a few seconds
aso there must be a way to make this new image the active one in script ?
i tried with a moon image and cannot see it on a plane in viewport but can see it in render!
