Build 3015

Hi folks,

Build 3015 has been released! Besides fixing some bugs, and a few smaller tweaks, the primary focus is improving a device I’ve never been completely happy with: the Thermal Weathering device.

The old version of Thermal Weathering had its uses, particularly in concert with the erosion device to help shape the sometimes over-steep slopes produced. However it never fully achieved its primary goal: to simulate the way freeze/thaw cycles break down rock faces and produce talus slopes.

I’m happy to say that the new version excels at that task!

Let’s take a quick look.  This is one of the example files included with Build 3015. Here’s a  canyon-type terrain:

Standard Erosion Only

Right off the bat, we can see that this is not a situation where WM’s erosion model traditionally excels. None of the natural forces that would dominate in this situation are being simulated, leading to a result that doesn’t look realistic. Among the problems are the lack of debris at the base of the cliffs, unrealistic streamlines down the cliff faces, and more.

So let’s try to fix it, using classic World Machine 2 Thermal Weathering:

Old Style Thermal

In some ways this is an improvement, but in others, a step backwards. Talus and other debris have begun accumulating on the slopes, but not in a consistent way or in a location that is actually where you would expect. This is due to a variety of reasons I won’t go into here, but the short version is that we still don’t get our talus slopes.

What’s worse, all of the nice erosional detail in the rocks that we created in the first world has been smoothed away. Sometimes this is desirable… but typically not.

So. Let’s take a look at the new version:

New Thermal Weathering

Hopefully you can see why I’m quite excited and proud of the new device. 🙂

Convincing talus slopes have been generated under the cliff faces. These slopes have a consistent (and controllable) angle of repose, as much volume as you want, and best of all not only preserve but even enhance the original erosion detail present.

The new device works great with or without traditional erosion. It’s also much more controllable than the old device (which was often a bit tweaky), has controllable mask inputs for both talus generation and talus sinks (where things like rivers can remove the talus), and, by the way, scales dramatically better than the old device in high resolution worlds — you’ll find some huge build time improvements.

In short, for most general purpose work, this device represents a giant leap forward, and finally deserves to be used on an equal basis with the regular erosion model. I’m excited that it’s now available, and look forward to hearing if you find it useful!

 

State of the World (Machine) 2017

Hi folks,

It’s been quite a long time since the last post here!

The latest development build (3014) of World Machine is available today, and that will be a whole topic of its own. Briefly, the two most notable and immediately useful new features are a major reworking of the River device to fully support multiple rivers and hierarchical river systems, and a usability improvement that lets you view the “before and after” of any device in the 3D View.

 

The next blog post will be about using the new modification to the River device.

But this post is about something else. The last post on this blog was about 14 months ago — what happened to 2016?

Seemingly a little, actually a  lot, and many lessons learned the hard way.


The Bad, and What I Learned From It

Let’s face facts – I, more than anyone else, am painfully aware that I seem to have disappeared off the grid in 2016. This manifested in two main ways. First, there were no new releases in 2016. Second, I wasn’t active in the forums. To make matters worse, there was no public information as to why. Yeesh. I heard from a lot of folks via support tickets and emails during that time: some were concerned (are you ok?), some confused (does World Machine still exist?), some frustrated (dude, are you ignoring us?).

The short version: I’m OK (thankfully), World Machine absolutely still exists and is what I exclusively work on, and for that last part, I sincerely apologize, but am taking steps so that this sort of absence doesn’t happen again, starting with this blog post.

Everyone knows running a business is challenging, but what I didn’t expect is that it continually becomes challenging in new ways I wasn’t expecting. I started World Machine as a side project because I love mountains, computers, and the act of creation. Then I realized I had made something people could get a lot of use out of, and devoted myself entirely to running this business, quitting my corporate job. Since then, that’s been World Machine – me at my computer and lots of coffee, exploring how to make this software I love ever better. I created the forums with the vision of having a community of people all passionate about creating worlds, that could support and inspire each other, and enjoyed being a part of that same community myself. I looked forward to interacting with any customer that came along, happily answering questions, even if they were just teaching new users the features. It was fun and I could run the whole thing while still having plenty of time for big sprints of development.

But here’s what I never saw coming. All that was easily doable when there were a couple hundred users. But as World Machine continued to grow, the time devoted to handling the administrative and support side grew with it and sorely tested my ability to handle everything as a one-man shop. I’m amazed and grateful at the success World Machine has seen, but its success greatly reduced the time available for each part of the business – development, customer support, forum engagement, and generally keeping users updated (like the website and this blog). And those last two were the first things to drop.

I’ve finally realized this, and am looking to adapt to the new realities of World Machine’s growth. Here’s a breakdown of what I’ve learned and how things are changing.

Let’s go back to that first most obvious disappearance. After a long cadence of multiple releases per year, there were zero releases in 2016. This left anyone who had purchased a license upgrade expecting to receive, well, upgrades, likely quite upset, and understandably so. In an ideal world, I would aim for quarterly releases, but it’s not always that simple. For example, 2016 was a year with substantial time poured into speculative R&D projects, trying to do things that haven’t been done before. Some of that effort has yielded extremely promising early results; however, other efforts consumed month after month of work, ultimately never producing a viable product. To make matters worse, since much of that speculative R&D work was entangled with the changes to the River device, it impeded my ability to get any other features out that were production ready.

What I’ve learned and what’s changing

  • The first major business update is to make sure the upgrade policy is fair to everyone. Going forward, if World Machine does not release a new version within 12 months of purchasing your license upgrade, you’ll receive the next (Development) version once it is available, even if it’s beyond the 12-month upgrade timeline. Also, anyone who purchased a license upgrade between December 2015 and December 2016 has already automatically received all 2017 updates free of charge, not just Build 3014, just to say thanks for your patience and support last year. I can’t promise how often I can get new features in your hands, but I can promise that a 12-month license upgrade will actually provide at least one upgrade!
  • Next, I’ll be making additional efforts to keep the speculative R&D efforts on separate development branches so regular releases can still go forward despite stalled experimental progress. I’m also going to be better about splitting dev time more equally between near-term and long-term improvements. So if there’s a feature you’ve been wishing for, I’d love to hear what it is. I’ll be looking at the forum under the “New Feature Requests” topic to see where there might be things I can get into your hands more quickly.

Now let’s address the second part of my disappearance: no activity on the forums. This was very different than previous years, and made it seem like World Machine had been abandoned. While I was able to (mostly..) keep up with support tickets, emails, and other administrative requests, that plus development just flat out didn’t leave me time to nurture and provide support to the community that I longed to create and be a part of.

Despite my desire to help every customer with questions, it really is too much for one person. So for the first time, I’m looking to bring on some help with the creation of a part-time position: Community Liaison. If you’re already a pro at World Machine and are looking to help people out and bring in some extra income, shoot me an email at stephen@world-machine.com.  My vision would be for this person to help run the forums and a few other points of customer contact, answer questions and brief me on how things are going there, as well as to help keep lines of communication up during long development pushes on my part. Hopefully, this will help keep the community informed and help me more efficiently wade through that data.

The Good, And What I’m Really Excited About

Not all of the R&D efforts were futile. I’ve developed some incredibly promising new functionality, but haven’t ironed out all the issues yet. This is what’s both so exhilarating but also demoralizing with new possibilities – there’s no clear path to follow to make it work the way you envision it.

But regardless of big and exciting new developments, I’m committed to working on the easier, smaller features as well. That way, even as I pursue what sometimes seems like rabbit hole after rabbit hole.. only to find zero rabbits, there are still upgrades to be shared.

To give you a little taste of what I’ve been so excited about that I spent months of 2016 pursuing it, here’s a basic World Machine world transformed by the application of some of the new devices:

 

Basic Terrain, Basic Coverage

 

After a few new features are applied 😉

 

So. although 2016 was a rough year for World Machine progress, 2017 will get to enjoy the fruits of that labor. And that’s a great thing.

 

Undo Support? Could it be?

Yes. Riverpreview 2 should be out tonight and includes a basic undo/redo stack. You’re welcome. 🙂

It also fixes a number of other issues that have been found so far. Let me know if you run into any problems, including actions that are not undoable, etc.

Further afield, there’s some very exciting new potential features coming up on the dev branch, too. My next post will detail a few of them…
