I haven't had a chance to try v7 yet. Though I'll see if I can soon. I did notice this though:
-rod now has model, and I have found a way to fit more catchables into the rod (I dont have any other models though)
I'm not entirely sure what you are going for with new catchables. If you want only more rare and expensive fish, or some type of moon fish. But if you want to keep it simple using already existing models.
You could use the
boot model as a cliche joke "fish". Selling very cheap.
Simple texturing over a crate could make a fishable
Box 10 pairs of Boots.
Also I'm not sure if it is possible to do this within the actual source engine. But there's always cheaping out and having
Baby Sharks, just scaled down versions of the Icthy's. Selling more than the other fish.
That's of course if you want to cheap out a bit, or don't mind using cliche fishing jokes. =)
Love watch your doing with the map, and love what you've got so far. This is coming from someone who hates farming style maps. You added a whole lot of things to keep it interesting.
I'll go check v7 out asap.
