I make 'pinupwear' because that's the type of art I make, and it's what sells. Now and then, just so my portfolio isn't solely full of 'fit caucasian pinup girls' I try something a little different, and every single time the sales are disappointing. The biggest slap in the face (and I'm not referring to anyone in this thread, just making an observation) is that often the people who most vocally demand that specific item don't even buy it once it's made. I do more than my share of charity work (IRL and 3D) and I actually have bills to pay. If I'm going to spend a month making something I'd rather it be something that I know hundreds of people are going to buy for sure than something that 'maybe' 50 people will buy, but most likely even those asking for it won't.

Poser content is incredibly time-consuming and finicky to make, and it's why there aren't that many vendors still sticking around making high quality content. It's why professionals from the industry come here, try their hand at a Poser item, realize how much work and fiddling and 'Poserizing' it's going to take to make it into an actual marketable item, and then leave. I can make and texture any clothing item in a day... it's going to take me at least a week(s) to get it functioning remotely the way I want it to in Poser, and then a week to package it, write documentation, put it through testing, render promos, etc.

That said, it's not a bad idea market for up and coming vendors to try. If I was a baker and moved into a town where there were already ten established bakeries and donut shops, rather than open an eleventh maybe I'd open a waffle house instead and be the only one in town. If you are looking to make a name for yourself then it's a viable strategy to cater to a smaller, specialized market than to drop another product into the sea of existing mainstream products.

I would (and often do) happily help people... the problem is that the Poser community is notorious for not helping themselves. Everything has to be spoonfed. I've lost count of all the times that someone has posted in the forums that they'd really like something, and I've taken a day of my own time to make it for them for free... and then they're like 'but aren't you going to conform it? I don't know how to use the cloth room' or 'thanks but it doesn't fit the breast morphs from this add-on'. I modeled a complex set to help someone a while back and they wouldn't even take the time to learn how to apply an emissive shader to it, they just said 'it doesn't work'.

When I started out I was a total Poser noob. I started making transparency maps for existing clothing items to make 'shredded' textures, then started improving skin textures, then making my own.. morphing figures.. modeling.. etc. It started out tweaking content for my own use, then creating content for my own use, and when people started asking for that content I gave it away, and when I thought it was good enough I eventually started selling it. There's totally free software (Blender, Krita, etc) and built-in tools available nowadays that blow away what was available back then.

Just the Morphing Tool in Poser has the ability to solve about 90% of Poser problems. Reshape figures/clothes, fit clothing, fix joints, flex muscles, reverse deformation, tweak morphs, make complex expressions, etc. I've been using ZBrush since it was released, but I'm hitting the GoZ button pretty rarely these days because I find the morph brush can fix things faster, and seamlessly right inside poser (and mirror in 1 click). I used to refer to it as a 'ghetto Zbrush in Poser', but it's not so ghetto anymore. If I asked for a show of hands of how many people used the morph brush in just this thread alone I suspect it would be a small minority.

As a community, people need to collectively push SM to overhaul the cloth room. The current cloth engine is 15 years old. It's 2019, dynamic cloth should work (nearly) real-time and seamlessly and intuitively in Poser. It would solve most Poser problems right away. There would be no 'Steampunk Dress for Sheila v3.2 (fits for 3 FBMs included)'. There would just be a 'Steampunk Dress'. Period. You could fit it to any figure past present and future, including any morphs, and it would drape like proper clothing should drape. You would see a much wider variety of clothing and people would take more risks regarding content.

In the meantime, the tools and shared knowledge are already out there for people to take their Poser art to the next level. There are helpful, knowledgeable people in this community that are always willing to lend a hand or at least point you in the right direction. It's just that very few people are willing to make the effort.
