How to i send the 2 files the .wrl and .png to print? use .zip ?

you should have the material embeded inside the WRL file. if not you can always email it to the guys at kraftwurx here after you upload. just upload your file and then call or email them to make sure it looks ok to them. unfortunately you can't see your model once you upload it unless you sign up to be a seller then you can see your models when you upload them. These guys are great! and if you have a question about your model then just contact them and they will open it and see. remember if you are having issues uploading it.. it is probly because you have holes in your geometry.

When you upload a model. .wrl files can hold solid color information without a color map. That is called "Poly Coloring".

But for texture maps with detailed colors you have the option to add a texture map image file in the model publisher window. There you can add the .jpg, .bmp. or .png image file for your model.

Upload you model first. Then select material as Multi-Color Sandstone. Then click publish model. There you can upload a texture map.

Let me know if this helps.

ahhhh good info here. my model was just solid colors so that is why it worked for me Thanks Marco!

Good, Marco... I did this process initially, but apparently had too much density on the model, making it huge. Perhaps some guidelines for Kraftwurx parameters for size, density would be good... if they are here someplace, a link would be great.

I prefer the bronze feel, particularly for the western stuff

It is very hard to determine a good set of guidelines for how much shelling a model should have. Because this is based on the given size of the model in zbrush. As a rule of thumb. I typically start with a low number like 10 for the shell thickness. It is a trial and error sort process.
