Attribute node returns flat white on xpTrail per-vertex color regardless of Name field

[swilkerson101]

Hello I'm trying to get my XPtrails to have the same texture and color as my particle emitter, but the attribute node returns flat white on xpTrail per-vertex color regardless of Name field, while W coordinate/Gradient map on the same geometry renders correctly. Is there a bug or any reason why this function still does not work. I looked in the forums and the last post about this subject was over a year ago. Has there been a fix to this problem, or is this something I need to talk to INSYDIUM about? I have attached my project file below.

Hi,

I suspect that the issue is caused by Chinese name attribute:

Trail color works ok here with english name attribute:
