I've never edited or hacked a model. This will be interesting. I have built spaceships out of code, so am not afraid of a few numbers IF I know what they are supposed to be doing. :determined grin: I do art on the Mac, so the graphics programs reside there. This Win98 box has Notepad, Wordpad and Word (and my lovely preferred version of WordPerfect 6 for DOS, but the computer hates the printer and there are driver problems). Word has wierd formatting issues. Will Wordpad be able to open and modify the file? Also, Windows boxes try to save everything as .txt even if I want a different extension... hmm... I can fix that on the Mac if it does get snitty. So, basically, I open the file, find the right section, copy it again under itself, and change material names. Nothing will happen to mess up the groups? Do the g names refer to groups, and should they also be unique so that the layers are differentiated in the render materials window? It promises to be a rainy weekend. Thank you for the kind words. If the final image is anything like what I'm holding in my head it will be worth doing. (There is a chapter in the Silmarillion where the trees of light have been killed and drained and Varda is looking out over a Middle Earth illuminated only by the background stars she'd called into being earlier. She reaches into her reserves and makes more stars for us, carefully naming and placing them. I want to show her against the sky so she needs to be somewhat transparent and even more sparkly.) Making stuff look like glass or milk is fun, but I wish that I could get it to glow properly. (The code mentioned above was DKB before it became POV - I got used to having light sources inside my translucent objects... and layering textures.) Thank you for helping dig into this. If we can get a layered effect to work with any of these models, we will have another tool. :) Carolly
