Ok, so, managed to find a program that I can actualy use (Blender is basicly unusable without takeing some collage course in how to use it, in my opinion), and have been working on makeing some mesh objects by way of practice. The program Im useing (Hexagon) does not have a direct export to collada, so I am exporting to obj, then useing another program to convert to collada (Zbrush mostly, less sucessful results with Blender so far). I've done a few meshes that have turned out just fine. However, I have finished detailing one such mesh, and upon trying to upload, Im suddenly getting an error I didnt before. In the preview window, when I go to preview the physics for it, some of the edges on the model show up as red lines, and then when I go to upload it, I get an error saying "mesh failed to upload: Multiple errors while validating asset. NewAgentInventory_InvalidAsset. See log file for details." Doesnt tell me what or where the log file is, or what the error is about, or what is causeing the red lines. This has been happening for two days now. Has anyone else run into this and knows what's causeing it and how to fix it? Incase it's relevant, Im useing the mesh compatable version of Phoenix. EDIT: Also, the last two steps under the 'Physics' tab are all greyed out, so I am unable to adjust any of these to see if they help solve the issue.
