With some, it might be kind to point out that while they may be very familiar with photoshop, they may not be so familiar with the materials room and how to set all that up.  Not to say the information isn't out there if they should want to learn but it could be that is just beyond some skill sets.

The eyes I totally agree about.  It is an absolute pita to have to go through every single eye texture I purchase and remove the lights.  So much so that I don't buy character sets at all anymore. 

I have participated in creating a character set - Still not up here at renderosity but it is up at the bad place "Bargash"  anyway - we took great pains to do alot of what you have said here.  I think it shows through in the quality of the Character.

To the merchant who got all uppity about it, LOL, me -personally I will gladly take the advice and I imagine those that purchase my products will in fact be paying my salary so - Thank you to them!
