How to get Rhino to refresh an obj skin?

Hi,
V5

I have imported an obj made by Agisoft metashape (2.2.0 the latest) , worked on it , but eventually having rotated it to correct angle, see its too dark now to work with.
I study Agisoft and yet again the export model had the vertex colours option greyed out.
It is erroring . had to go Tools> model> generate vertex colours, then export the obj all over again.
In Rhino I select my mesh and browse to the jpg, select it, BUT THE SKIN REMAINS DARK

If I import the redone obj then allocate the skin its then the right colour

BUT I have done various scaling and rotating and stuff to the original obj,

I AM NOT REDOING A DAYS WORK AGAIN.

How do I get the re-imported mesh to be same size as the existing ?

or how do I force rhino to take on the corrected skin ? that would save a lot of messing about.
Surely re-allocating the correct skin should have updated it ?

and I wish Agisoft would fix this new error, never used to do this. and fix alugn photos error and also softy fuzzy areas error.

Hi,
I had a bell icon on my motif, click it and see Wim, but no message, but see a double of my post, and see no method mentioned on how to force a refresh.
puzzled.
