I've recently been thinking of putting an asset pack together, and was wondering how I should do that.
They'd be ones I made in Blender and possibly ones I made using Gimp. Mostly food and beverage related items as well as a clock, and possibly some furniture, such as a nightstand. That kind of thing. They would be items I've used in games, as well as items I haven't.
I hope that answers your question.
A good first step would be to have a look at other people’s asset packs. There are several of them available for free, so you can get a very detailed impression of what people would expect from it. (And maybe consider donating to the asset pack that helped you the most…)
A good second step would be to add a space and capitalization to your user name. It will look more professional that way. ;)
