Hi,
The node has already been updated for Revit 2022/2023.
There is no need to do any unit conversion since it is already built into the code.
It seems more related to this post :
According to my research, this is due to the fact that some of your textures do not have a 1:1 aspect ratio.
Either the API does not reflect what happens natively in Revit with the sliders, or the ratio should be taken into account in the code.
Unfortunately I don’t have the free time to devote to it.
