From what Ive seen/read so far lots of 3D stock agencies require PBR models so substance designer files are going to become quite mainstream so a good option to get ahead of the curve if you can. If you take a look at poliigon.com you can see they are selling generator files now (and I think will be focussing more on this as time evolves).
A quick comparison with their credit pack shows you that they themselves value substance packs higher than 3d models (probably because of market scarcity and niche).
Lets break down their pricing before we evaluate things. Without being a subscriber you can buy a credit pack, best value is 125 credits for $30 ($0.24 per credit):
Coffee Table Riverside Replica 001 - 3D Model
25 Credits (about average on this site)
$6
Upholstery Generator - Substance SBAR file (for use in Substance Player)
100 credits
$24
So on average they estimate the value to be 4x higher than the average 3D model.
A few things to think about:
- They do have very good sbar files with many options available for the average artist who needs no deep understanding of substance designer.
- They work fast, you can compare these to other free ones on the market and theres some lag maybe in regards to how the artist set up the file not sure.
- They also release video tutorials on how to use them, bonus points here in a few regards
- Giving the artist many options to variations is key here, I think more people will be using these now as everything goes PBR/realtime and the easier it is for artists from industries who have little R&D time (archviz especially) would pay good money for time saving tools.
