Yeah, it's all optional - kinda depends on how you feel about your stuff being used. Me, if anybody used anything I have in freestuff in a commercial render I'd be so busy pissing in my pants for joy I wouldn't care. :lol:

Now repackaging and reselling something I'd created would be another issue entirely. Then, everybody would find out that yes, I'm part Irish and have the temper to match. :scared:

YMMV, of course. :laugh:

Seriously, it's up to you, and nobody should criticize you for making the choice you feel comfortable with. And, like you said, you can always quote pjz99.

You're already falling
It's calling you on to face the music.
