Texture size question

[Ostapas]

Good day,
let's say, I create a model in Sketchup using photomatch and export it
to 3d game engine. However the model's texture sizes are not power of
2 (256256, 512512, ...) and 3d engine only accepts these. Anyone can
suggest a method, tool or software how to batch resize (to standart
sizes) and reapply the textures? Doing it manually is a real pain,
especially with complex models. Thank you.

Hi,

There are a whole lot of applications that can batch resize images (at home I use the simplest Windows tools for this).

If you resized an image, you can reload it from the material editor (click on an image there and go to the edit tab). Now I don't know how this - resized - image would "behave" with photomatched models though.
