For this week's video. SCEA software engineer Greg Corson, who has worked on interchange file format COLLADA since 2005, talks about taking advantage of the format with game development tools such as COLLADA Refinery and Coherency Test.

Corson believes that COLLADA is helping developers move away from using custom-created solutions and formats: "This was the same issue in the movie industry -- they all had their own custom software, or they bought all their software that they used from one company. Everyone realized that they can't really do that anymore. No one company has everything that you need to build a game or to do a movie.

He continues: "It's getting more and more important that you have a lot of tools that work together. Other tools tend to get discarded now, instead of just worked around. That's a big change for the industry, finally seeing everyone say 'We can buy tools from anyone we want and have it work.'"
