Penumbra Collection HDTEX Mod - WIP/WID

[wabo]

Blender I guess, maybe some option in the program you use might need to be changed or maybe the files are read-only? I cannot really help anymore on this. Try blender if the above fail.

Locked means "Read only" in OSX so I guess I'll give a try with Blender. Luckily, it'll able me to open and "fix" the problems so models can then be used in SketchUp. Is not the first time I've heard such errors (ie file X created with a program, then open in another program and save to let other program open it... all the time the same filetype).
