I'm wondering if a friendly neighborhood Shapewayer has some experience preparing Sketchup files for full-color sandstone. I have a model (which, as a first-timer, I'm darn proud of), but I'm not experienced enough to figure out why my various filetypes (.skp, VRML, etc.) only ever import as gray. I've gone through the FAQ and forum-advice process but still don't quite understand folks' instructions. Would someone be up for "proofreading" or troubleshooting my model, both to get it to print in full-color sandstone and, since I'm so new, walk me through me how to do it right in the future?
