Hello I am checking out Open GL objects and am having an issue with the help file for the jit.gl.mesh object. When checking toggle switches for the auto_normals $1, auto_tangents $1, auto_bitangents $1, auto_colors $1 messages and the prepend color_mode drop down menu I get red errors in the Max window along the lines of "failed to auto generate tangents!" "source data does not exist: " " failed to generate auto colors!" and so forth.

I restared Max and get the same thing. I'm running the latest version of Max/MSP on a very new iMac.

It is likely that I am missing something here. Any advice is greatly appreciated.

yeah that is a bit weird, I also get the errors in the max window, but up till now I haven't had any use for those particular auto messages. You can always set the colors and everything by yourself check the tutorials for more info.

as mentioned in the reference file auto_tangents/bitangents need normals and texcoords.

auto_colors looks at the color_mode attribute to determine what generates the colors. the default is none, which is why the error shows up. hopefully this patch explains:
