# Where to set 'use_blender_profile' option?

I have seen that the Collada exporter uses a flag called use_blender_profile.

Looking at the source file, it seems that this option allows to export additional information in the Collada file :

• connect to say if the bone is connected to its parent
• tip_x, tip_y, tip_z to tell the length of the leaf bones

Without these values, the information is lost as Collada encodes the armature differently.

But where and how use_blender_profile can be set ? Am I right about the exporter behavior ?

The blend file :

• I would report that as a bug. The code appears to be there and there is no conditions to show/hide it. It is listed in the rna/dna files and it's in the operator and layout functions with the other options that are visible. I don't see any reason the option should not be available during export. – sambler Jul 7 '16 at 3:46
• @sambler thanks, have a look from the line 177 of ArmatureExporter.cpp (current version). How to report that ? – lemon Jul 7 '16 at 4:19
• That's where the option actually changes the exported data. The problem is earlier in that the option is not made available to be turned on/off. You report the bug at developer.blender.org, you can simply write file xx/yyy/this.c or you can add links in the bug report the same as here using [text](link/to/file$linenumber) adding $177 to the end of the url will reference a specific line. – sambler Jul 7 '16 at 4:42
• OK... first time I do that, but done : developer.blender.org/T48801?workflow=create. Thanks @sambler – lemon Jul 7 '16 at 5:54
