Maya Quadrangulate Workflow

Here's another long video I created. I talk about converting polygonal meshes with triangular faces to quadrilateral (or quad) faces, using the Quadrangulate command in Maya.

First I talk about using the command with its default settings. Then I go into more tricky situations where the command does not work the first time, and how we can still achieve a quadrangulated geometry in the end.

In summary, the most important settings to take note of, from the command options, would be:

- 'Keep hard edges' checkbox (I always turn it on. many external applications export meshes with all edges hardened. In which case, the command will not perform any quadrangulation)

- Angle threshold. The lower this number is, the more choosy Maya will be when deciding when 2 triangular faces are to be turned into a single quadrilateral face. 0 will tell Maya to quadrangulate 2 triangular faces only if they form a perfectly flat planar surface (ie, only if they are co-planar). A maximum angle threshold of 180 means that Maya will take all possible pairs of adjoining triangles will be converted to quads.

I hope this helps you in your mesh clean-up.

Search Algorithms for Game Play: Going from A to B

From a blog post on Packt.com, my favourite resource for software development related books, I came across an article that talks about Search Algorithms.

In the post,  Daan van Berkel talks about the processing, logic and steps involved in navigating a character from point A to point B in a game engine.


Having no previous knowledge of path-finding, I find this immensely intriguing and an enjoyable read. I am definitely interested to find out more!

nVidia iRay Test Car Render - Maya

After the completion of the Future of Us Launch Video, I took some time to test Nvidia's iRay renderer.

http://www.0x1-software.com/iRay is included in 3D Studio Max 2015. However it is not included with Maya. I found that the company 0x1 has implemented an iRay for Maya plugin, sold as a commercial product.

Using the car model from the previous project, (which was purchased and modified), I set-up iRay shaders for it.

The background image is being used as a source for image based lighting and reflections.

The depth of field and motion blur are in-render, rendered as a single pass. Each frame took 12 minutes (cpu/gpu batch render) on a dual Intel Xeon 2.5ghz with 64gb system RAM, and an nVidia Quadro M600. (This is the machine I'm using at work).

iRay for Maya is responsive. I really love the interactivity. I have not tried rendering in passes and compositing images with it, but from the video links for their product site, it seems quite possible to achieve a passes-based workflow like all other renderers.

iRay for Maya is available as a 30 day trial from 0x1 Software and Consulting.
