well, i reverse engineered the format. it is human-readable. i just made a parser. i'm sure once valentina gets a bit more complex a more in-depth look will be necessary (requiring to look into valentina's source), but at this moment, it is kind of straightforward (i would suggest working on the curves though). please note that my focus is to have an alternative to marvelous designer. valentina's value for me relies on it's GUI. i was going to make one of my own, and that was when i found valentina.
i really do not expect to earn much money, but i promise i'll use the donate option to pass some of the earnings and support the project. to be honest part of my intentions are aimed at helping the cloth simulation plugin makers (syflex) to further develop their plugin, i love it, it is blazing fast, but with respect to them, their GUI ... well, it's not good... i just want to also sell the plugin as i don't mind (and need) some income in the process.
it also occurs to me that the greatest benefit will be that any person that gets the plugin will need to get valentina, putting valentina on the spotlight. something i also find interesting for you guys to consider.. is creating some sort of e-commerce.. like what blendermarket has (note blender is GPL too!). actually, if some of you guys have some sort of valentina library with different clothing pieces, i would be saving money to buy right now! (as long as it is not too expensive, i live in south america, and stuff is a bit more "expensive" for us due to the exchnage rate).
i'm not a cloth designer! marvelous designer also sells digital clothing (at basically the same price that the same garmet would cost in real life, hahaha). a way we can all get support for valentina is to create a shop. with the additional advantage that valentina is not foucisng on the 3d modelling groups (kind of small, everyone uses zbrush for this), it basically focus on everybody. anyone that needs a pattern for making a real life shirt, can buy it and printed out from valentina (and adjust parameters too). i think the potential relies there.
in summary, i do not design clothing patterns.. but i am in need of some! i will be the first client!
regarding the plugin, i am already using it myself. but in order for it to become something third parties can use i still need to make some modifications, and i am trying to get the quads algorithm to work. the valentina importer is like 10% of the plugin's code, the heavy lifting resides on the meshing part; there's also the UVing, and something i haven't implemented yet, is that i want to keep valentina's variables. it also requires some sort of GUI. anyway, once i publish the plugin (initially for modo), i'll let you guys know.
and don't worry, i of course intend to pass some of the earnings.
