Pixelation of 3D meshes

Hey guys,

I have a few 3D colourised meshes (.OBJ and .PLY files) made in pix4d mapper.
The meshes have a .mtl file and a .jpg file, they are not georefrenced but I georefrence them by using the EDIT>APPLY TRANSFORMATION>AXIS ANGLE>TRANSLATION. I use a offset file pix4d provides.

Now the problem is when I import the mesh it looks perfect
Before moving.JPG
Before moving.JPG (226.05 KiB) Viewed 4699 times
but as soon as i georefrence the mesh the image becomes exremely pixelated or jaggered.
After moving.JPG
After moving.JPG (246.58 KiB) Viewed 4699 times
I have moved meshes before without any issue but I have not changed anything in this process except the drone I used to for pictures for the mesh.

any suggestions?

Regards,
Damon Saunders

It looks like the coordinates of the vertices are too big.

Do you see it pixelated right away (after translation) or after saving and reloading it?

And does CC suggest to apply a 'global shift' when you transform the mesh coordinates?
