Unwrapping on 1024x512, or two 512x512 texture sheets

[reeke]

i know a way of rendering out the uvw so its on two 512's, but is there a way of doing it so they dont overlap coordinates? i wanna make a high poly version of the model so that would cause problems when trying to bake out the normal

Edit: Doh, supose i could just use different mapping channels? let me know if theres a better way.

I would go with seperate mapping channels
