all good points.
personally I wouldn’t ever get into trouble with any assets that are code or bp related in terms of upgrades. I can see me being upset if a model pack or something wasn’t supported in a new version maybe and I didn’t know how to fix in maya or something.
Obviously it makes no sense to require support is “forever”. I guess most purchases in real life come with a year warranty by default.
I guess the buyer also needs to take responsibility for the purchase. Don’t buy things you can’t “upkeep” yourself in the future if its a concern. Seems like a fair statement.
In terms of the support being worth it, I hear that for sure. I have a couple of tools I’ve built I considered releasing but ultimately decided not to because of the support/time commitment.
