I was just wondering why you don’t have a version of your software that is free of charge to encourage people to learn it. Wouldn’t it make more sense to have a version people can learn on, in order to promote its use in larger studios? Wouldn’t it just make more people want to use your product, if you had more people showing off what it can do? It would also be a way for someone to add a knowledge of Zbrush Software to their resume, without needing a 400-600 dollar license to legally be familiar with it?
A lot of other companies have versions that have trial licenses that last for up to 3 years to allow someone to familiarize themselves with it. If your worried about someone abusing your software in a professional setting, then digitally watermark the model etc so that unless it is saved and compiled on an official version it would be easily identified among a games assets.
That is just my personal opinion. I would find it interesting to self teach myself Zbrush, but I prefer to learn software when possible on free versions. I know at least a half a dozen guys who were interested in learning Zbrush but gave up because they didn’t have legal means to get a free version to learn it on. If you think about how the Unreal Engine has been adopted by so many as well as the Unity Engine, you can see just how they have driven their product by making it freely available to learn to those that choose to pursue it.
You would also likely find tinkerers and others playing with it in a variety of ways, and likely informing you of bugs and perhaps making very useful plugins that your entire user base might make use of. Think of all the games and new game developers have emerged from the ether because of the Modding community, and free tools that have let them pursue their dreams. A learning version of Zbrush should bring in a wider array of end user customers; since they could then require prior experience with it from an applicant, who could spend their time learning it on their own or whatever. I think requiring prior Zbrush experience is likely not on anyone’s list of pre-requisites at present. With a free learning version that could totally change.
Anyways that is just how I feel about it.
