RemapPSD

An example case: You have worked on a lowpoly game character and are almost done when the lead artist approaches you with the request to give the character's face more space on the texture. This is not so difficult if you are working on a flat image, but impossible to do with complex photshop files. With RemapPSD it's inredibly easy. You can change the uv-layout of an existing model and the psd file with all the layers, folders, adjustment layers, masks etc, will be remapped with just the click of a button.

I hope you will find it just as helpful as I do. To get started it is probably best to watch the video tutorial on vimeo:

INSTALLATION:

1. Select Maxscript/run and choose „RemapPSD.mzp“
2. You will find the macroscipt under customize in the category „3dhippie“. Assign it to a shortcut or make a new menu item.

USAGE:

Basically you need three things to make the script work.

1. Any piece of textured geometry
2. Two sets of UV's: Channel 1 for the old mapping, Channel 2 for the new mapping
3. A standard material with a bitmap texture as it's diffuse map

RemapPSD will do the rest for you.

The script will run through four phases:

1. Photoshop will pop up, open the document, save it under „[originalname]_remapped“ and do some preparations.
2. Back in 3ds Max render to texture will render all layers.
3. Photoshop will collect all rendered images and update the psdfile.
4. In 3ds Max the original object's material will be updated to use the remapped psd file.

That's it. You can now continue working on your psd file which will be organized just the same as before, with all layers, adjustment layers, folders and so on.

LIMITATIONS

You cannot remap vector elements, such as vector masks, or text layers, or smartobjects. All of those elements will be rasterized.

Long layernames will be truncated.

SATISFIED?

If this script has saved your life maybe you could donate me some money? I have setup a paypal donation button on my blog: http://davidshelton.de/blog/?p=249

I am looking for part-time or full-time positions as a 3d generalist in the games or films industry, as well as for freelance jobs. Please take a look at my current showreel:
