Quote - I have been using matmatic extensively for the hundreds of materials I include in the products I do with DreamlandModels. I made a couple improvements I will publish.

So, I'm assuming the Feb 2nd release (1.5.0) is not what you're referring to, here, BB?

Sheesh, it's been a bit since I've done much in Poser, but that's soon to change: I'm looking at doing scenes/sets at the moment. Working on a 221B Baker Street Victorian era set at the moment, which will definitely not be a for-sale item, since I'm using it as a Blender modelling learning tool. But there will be extensive material management needs for this set, which your improvements to matmatic should address nicely.
