I’ve done a test render using Blender and Luxrender at 720p to test out the limitations of animation using Luxrender. That’s why I’ve used multiple materials.
The clear poor performers are the rough glass and glass materials. Render settings were adjusted for high speed so I’m actually really pleased with how well most materials render at with only 2 minutes per frame. For future animations the time necessary for clearing up even the glass materials should be reasonable even at HD quality.
No sound, sorry. Also, apologies for fireflies and the “T” cracking a little too early. Physics were calculated with Blender’s internal game engine bullet physics. Letter shards were created using the “Fracture” tools plugin.
I’m very pleased with and have learned a bundle from this test! And hooray for my first YouTube upload!
