Dynamic system build along a single spline. Vein model and particle flow follow the spline.(see 'dynamic_splinebased_system.gif' animated gif for details)
Stacks of all models intact so you can very easy make it fit your requirements. (ex. strength of noise on vein or cell)
Bloodcells flow done with ParticleFlow.
Bloodcells source from 4 different models to get more variance.
Maxfile is very trim so everything will be found with one click. ( see 'MaxFile_LayerManager.gif' for details )
Depth of field and motion blur done with VRay and part of the MAX file. Materials all standard max and procedural.
Scene without any lights or GI, so very fast rendering. ;)
