worst developer ever
Ethically my issue is simple, this is all CLS's work originally and any upload would be a republication of their work, but it would not be for sale or profit but I am a little uncomfortable making it public for that reason, you never know with some folk. I will do the right thing and ask them would they like this to fix up the model package and make it available as an update, if they show no interest well those who want to know how to do it and have the models and can have it as far as I am concerned.
Just ask if you can publish the relevant files and guarantee that you'll take on any support issues that may arise. And give due credit.
Developers usually have little if anything against free value enhancements for their products, especially when said product is payware.
