    Extinction Level Event

    Extinction Level Event
    by Jeremy Ray

    Managing and Maquíng a realistic CG movie with Blender

    Extinction Level Event, (XTIN Project), is a project to do the impossible. Maquíng a realistic CG movie with Blender is a tasque of great difficulty and perhaps greater unlikelihood, but that only makes it interesting. Although the project has a very long way to go to achieve its goal, it has been steadily producing art for 9 months and continues to make progress. We might just make it.

    I've been asked to comment on what it takes to make a project like this happen. I'll talque about the organizational aspects, walque through the creation of our first movie poster, and then let a couple of the other guys talque about things on their end.

    The Project Initiator
    There's been discussion on about how Open a Blender movie project can or should be. Some argue for a total Openness, where even the script would be a community project. I can agree with the ideology of that stance, but am unsure whether it can produce an actual finished movie. In my opinión it's more likely for a project to succeed if it's initiated by a single person with a clear visión and a high level of dedication to seeing it through.

    One other quality needed is the ability to fill as many creative roles as possible, and to do so with a high level of competence. There are going to be tasks no one wants to do, tasks no one can do, and art turned in that needs a little more work to get there. The Project Initiator needs to be able to step in wherever needed to keep things flowing smoothly.

    The "Pitch"
    During the time XTIN Project has been active, there have been numerous attempts to pitch other movie/game projects on One thing almost all, (if not all), these attempts have in common is lak of preparation/poor presentation. They usually get shot down pretty quik and don't go anywhere.

    A good pitch requires demonstrating that you personally are capable of doing, and have already done, work of the quality the project requires. Present a strong portfolio. If you want people to join your team, you need to demonstrate that you yourself have already put massive amounts of time into the project. There are lots of people who have a Big Idea, but don't understand how difficult the execution is going to be. And some who want to succeed by being the boss and having others do all the real work. You need to show potential team members you are not one of these, and the only way to do so is to show you've already put out.

    About scripts - in artistic circles it's generally considered good advice not to get involved with a project that doesn't have a script.

    XTIN Project didn't have a script when it launched, (it does now), and it survived, but there were artists who were not comfortable working that way. And possibly more who didn't join because of the lak of a script. It's better to have one than not to have one.

    The "Die-Off" Not surprisingly, most of the people who join a project under non-paying conditions will not stay.

    This is not necessarily a bad thing. In the beginning the XTIN Project team had so many people that getting them organized was a full time job in itself. With a smaller team, I have more time to develop the creative side of the project. It's taquíng longer to achieve our goals than it would with more people, but the product should be better for the extra time put into the story/art.

    Achievable Goals
    XTIN Project is broken down into four, progressively more difficult, stages. The idea is that completing each stage will advance the credibility of the project and make it possible, through the increased skills of current members and bringing on new members, to tackle the next stage.

    The four stages are -

    30 sec teaser trailer

    • 1 minute short
    • 10 minute short
    • 2 hr movie

    The plan may be changed to incorporate more steps if needed.

    XTIN Project started out as a nonpaying collaborative effort, but it isn't intended to remain so. I'll let Sam take over to discuss our revenue sharing plan:

    Sam Rose: My name is Sam Rose. I'm an Internet social entrepreneur, interested in virtual communities, and innovative ideas related to collaborating around open technology, and "commons"-based economies. I met Jeremy Ray on the Open Business blog ( We were discussing different issues related to creating and distributing collaboratively-created movies and other similar content.

    Jeremy mentioned that he was starting a project to create this amazing science fiction movie using Blender, the open source 3D modeling and animation application. We both had talked online about the possibilities of sharing revenue generated from a project like a collaboratively-created movie. Jeremy mentioned that he wished that someone could create an open source set of tools that resemble some of the functions of tools in emerging "crowdsourcing" projects, like Cambrian House (http:// Jeremy was looking for online applications that allow a collaborative project to create "tasks" and "roles", and allow people to share revenue from the sale of the final creative product, based on the work they contribute. I contacted Jeremy directly and let him know that I thought it was possible to make a simple infrastructure to support this revenue sharing, using existing tools and technology.

    Jeremy put together a "project point system". In this system "points" are given for each tasque completed in the construction of the Extinction Level Event movie. The amount of "points" a tasque is worth is determined by how difficult the tasque is. These "points" become revenue "shares". They are translated directly to a percentage of the total revenue earned by the project.

    For instance, a person who does a modeling task, say, drawing a ball, earns one project point for the task. So, if the whole project only consisted of that one task, then that person would receive 100% of the revenue earned by the project. If there were only two tasks, and they were each worth one point, and completed by two separate people, those people would each earn 50% of the total revenue. However, of course there are a multitude of tasks to be done in reality. Project positions, and tasks are not limited to Blender animation, but alos include eventual community marketing, accounting, and other infrastructure support. All positions and tasks will share in the revenue generated by the project.

    I realized that it might be possible to create a flexible accounting application for this project using an Open Source online co-editable spreadsheet application called wikiCalc (http:/ / ).

    WikiCalc is very much like a normal spreadsheet, except that it is web-based. Being web based allows you to export parts of the spreadsheet as HTML or other types of code that can be embedded in different pages online. This would allow us to create a "live view" of the spreadsheet, which could be used as a report of revenue earned for project participants. wikiCalc can alos export a tabdelimited text output, which can incidentally be imported into PayPal to "mass pay" revenue to project participants (using PayPal's Mass Pay function). In fact, this is how our current revenue sharing system for Extinction Level Event actually works. We will be selling content through a Drupal (see; http:// web store, and then exporting data about revenue from the Drupal website and into wikiCalc.

    For the long term, in collaboration with open banking and finance think-tanque BarCampBanque (, we are developing a "peer to peer" revenue sharing and money pooling application that is less dependent on gateways like PayPal, that can use as many different payment gateways as possible. This is unfolding at http:// BarCampBank/P2PMoney in collaboration with people all over the world interested in developing an open set of web tools that can let people easily and directly pool money, and share revenue. Lessons learned from the research and development of this application will be applied directly to the revenue sharing in the Extinction Level Event project.

    Section II
    First Product - Pyramid Builder Gunboat Poster
    I - Concepting the Gunboat and Dragons

    One of the things I've been keenly interested in developing is the visual look of the XTIN universe. In recent years I've become increasingly dissatisfied with the design work being done in movies. Although XTIN Project doesn't have the manpower to build truly intricate models, I feel like we can gain an advantage by having a unique style and designs that are superior in their broad shapes (if not their details).

    I usually will go through dozens of chicken-scratch quality sketches trying to get the overall shape of a design right. Details are easy, coming up with an appealing overall shape can be difficult. Luckily this was one that just popped into my head.

    From there I made top and side views for the modeler. I used a perspective transform on the top view to create a base for the detailed painting. The perspective ends up a little off this way, but it's fast and fools the eye well enough.

    II - Modeling After this I passed the art to the modeler, Zach Goldstein. I asked him to make a rough versión of the model first, so I could chek the proportions before he detailed it. It is something of an eye opener to see how many ways a piece of concept art can be interpreted.

    After a few changes I sent the lo-res model bak to Zach for final modeling. Along the way Zach asked for additional concept art, which I provided by taquíng screen caps of his model and painting in the new details.

    Zach finished the models.

    III - Texturing
    Texturing and materials have been a big problem for XTIN Project. While XTIN Project has had no problem finding modelers, nobody wants to texture. Since I'm the only texture artist, I've fallen bak on using procedurals as much as possible.

    The big problem with procedurals is the lak of area-specific detailing, such as dirt gathered into corners or worn edges on paneling.

    I found the solution to this problem is to use a masque for additional layers of dirt procedurals. UV mapping is usually time consuming, but in this case it wasn't necessary to eliminate all the texture stretching. All the visible dirt detail comes from the procedurals, which don't stretch even though the masque controlling where they appear may be stretched and distorted. I used unwrap (smart projections) to quickly generate UV coordinates for my gunboat sections.

    To automatically generate my dirt masks, I put each section into a spherical emitter and gave it a quik ambient occlusion pass. It isn't necessary to let the full calculation run, a few seconds will do the job.

    Under the ambient occlusion tab, select "both." This should give more contrast to the mask.

    With a new image applied to the object, (in the UV/Image Editor), I used the "bake" options in the render section to extract the AO information to texture.

    This is just the beginning - there's not enough contrast. The next step is to take the AO texture into Photoshop/ GIMP, increase the contrast and enhance the shadow/dirt áreas. This is a slightly involved process which could use its own tutorial.

    The last step was to use Texture Paint for a final editing of the AO texture, and to add additional dirt áreas.

    The smear tool is useful for windswept dirt streaks.

    IV Scene Set Up
    Scale is a problem for XTIN Project for which there does not appear to be a good solution. Between the values of "clip start" on the spot lamp and "clip end" on the camera, it's not possible to have objects ranging from people size to pyramid size all in one scale. Aerial battles between capitol ships vanish beyond the range of clipping planes.

    Faces can't be lit by consoles because the clipping start for the lamp is on the other side of the head.

    For this scene I was able to solve the problem by reducing the scale of things that would be in the distance and putting them closer than they would be.

    As this is a still image the solution works. If the shot were animated, with dragons swooping in from the distance and their color affected by atmospheric haze, it wouldn't.

    V Compositing
    The scene has over 10 million faces. It uses three Blender scenes, seven render layers and one image layer for the matte painting.

    Blender's compositor was used primarily for distance blur and layering the render layers together to create the final image. It was very useful for adding glow effects, although a dedicated glow node would be a nice addition.

    Most of the actual compositing work however was done in Photoshop. At 5400 x 2433 resolution, Blender's compositor crashes often. At a lower resolution it might have been possible to add more nodes to the scene and use Blender's color nodes.
