Please advise how I can rotate a texture on a face by 90 degrees.
Dear Bernard Glossop
That is a good question, but unfortunately I cannot offer you a good solution to this issue.
There is no possibility to rotate the textures in Relux Desktop, I can understand why this could be very helpful in some cases.
On the other hand, Relux prioritized its light calculations over the visualization of a project.
Your own pictures and textures can already be imported rotated to avoid an incorrect display.
Please do not hesitate to contact me if you have any further questions.

The direction of the texture depends on the order in which the object is constructed.
you can try swapping the base points
or expand the texture in a file using a graphical program
