LightMtl & Texture Mapping

[SHORT CUTS]

I am not sure if its a bug but it doesnt seem right.
If i use a normal CoronaMtl and plug in a gradient ramp and map it onto a spline using real world scale everthing looks as expected.
If i use a CoronaLightMtl and plug in the same gradient ramp in the texture slot the mapping gets messed up and its not rendering correct. I attached two images to illustrate the problem, one with the normal CoronaMtl and the other on with a LightMtl. Nothing has changed except the material. Some parts are ok others are stretched...

Can you show the 2 materials on exactly the same part of geometry? (right now your screenshots are showing different parts)
I don't see a reason why this should not work...

Sorry to reply so late, we had to to finish the animation and i havent had the time. It seems its only a problem in this specific scene, i tried it in a new scene and it was working as expected. Not sure what went wrong in our animation but we got away with using a self illuminated corona material instead of a light material.

Maybe wrong material channel id? Moving to resolved until re-reported.
