Hi, has_face_color() is just returning, if the OpenMesh has a face color property. OpenFlipper uses face colors in several plugins, so the property will always be added automatically and not depending on the loaded file. Maybe we could introduce some information structure that provides information about the files which are loaded. Which box do you want to uncheck? Load face colors in the obj reader could be always on and will just skip reading face colors if they don't exist. Best, Jan Möbius On 19.05.2015 11:10, MBRSL . wrote:
Hello,
I'm using .obj for OpenFlipper. Is there any way to tell if a .obj contains face color or not from code?
I found that if I checked "Load Face Colors" in the popup options, has_face_colors() will always return true no matter this .obj contains face color or not. The resulting color is invalid if this .obj does not contains face color. However, I can't tell this from my code.
I would like to run a batch for several .objs that some of them contain face color and some others does not so I can't unchecked this option one by one manualy.
Thanks, MBRSL
