You have applied text over a shader domain in Carrara before using layer list. But sometimes it is very hard to apply the layers tool on some curved surfaces, so we will cover about the process of using shader domains to do that. Looks a little strange but this is a way to create labels with transparency very easy.
Nine minutes of faltering, halting, hemming, and hawing.
Remember, get the stationary point of the text where you need it first, set the Bend Axis Angle to 180°, and make incremental changes to Bend Angle to find the best fit.
