Kerkthea MTL + Depth Map

Original Output

After the deadline of the BFI competition project, I got a little to play around with this free render engine, the MTL algorithm is a more accurate one compare to photon mapping, especially in the details and edges. The best well know software that use MTL is Maxwell, and it ends up with easy settings and accurate light calculation. The biggest problem with MTL is the slow render speed and the grain, it needs more passes for each frame to get better result. But an advantage is that u can stop whenever u want and save the image. I use Tadao Ando's the church of light as a model, because its a simple geometry with simple light fittings, it will be the best condition to test the software, especially on the indirect sun light. After 20hr of render which I think its too much for everyday use, but the result end up quite satisfying. the indirect light do illuminate the interior and u get the fadeout effect on the floor of light reflections. Another very useful settings is the depth map, and it takes only seconds to get this depth of field mask that can apply to the original image in Photoshop very easily. There's no need of using DOF camera that take ages to render. I'm sure other program like Vray or Mental Ray can easily achieve this result and maybe better, but a software for free and with easy settings, it really done a good job.
