Thanks to everyone who pointed out that the initial release of Detonator did not play nice with Unity Indie. The Heatwave and its HeatDistort shader made it quite sad indeed.
Indie users note: After installing this package, delete Detonator/Resources/Detonator/Textures/HeatDistort
Update: Posted 1.02 – The fallback subshader in HeatDistort was not working properly. Now it is and you don’t need to delete that shader anymore. Woop!
