I have downloaded a large image from the NASA website that is a raw image of the earth from space.

I got it from here:

I opened it in Photoshop but couldn't save it as anything I could convert to a .rat file. I split it East and West and could save those as .tifs, but I'd really like to have it as one image for close ups of the earth.

Is there a way to convert a raw RGB image to .rat? Or is there a way to stitch two large images together in one?

Any ideas?

If this can't be done, I can split it into smaller images and use layered uv's, but that's a bit of a hassle since I have everything set up to do my displacements and spec passes with the uv's I have.

Hey Dave,

I haven't checked the rgb format, but will icp convert it for you?

It's just a raw binary format, rgb interleaved. There isn't a format for it in icp, as far as I can tell. The file has a .bin extension.

I think it should be able to use two separate textures? You'll need to split the uv space into two separate attributes and apply the textures using each one indepdently. (Eg uv0 uv1)
