The refresh button is definitely there in the Mac version. I don't have Carrara on the computer I'm using now, so I can't give you a screenshot, but the icon looks like a folder with a circular arrow or something like that. It's one of the icons next to the image preview in the texture tree. That button is not the greatest tool, though, because if you change a texture map you have to go open your texture in the texture room, unfold the tree to see the mapping, and click that button. I wish that that there was a global texture refresh command, so that I could reload several textures at once. Or better yet, Carrara could automatically detect when textures are updated (lots of programs have this ability - the game authoring system Unity, for instance.) - Joe
