Realflow River RnD

Hi Guys,

I worked on this RnD over a couple of days while I was finishing up on the Battleship Explosion Shot.

For College I am working on a project which will involve a river for a big amount of shots and was trying to spice it up a bit by using Realflow. I Modelled the River/Rocks in 3DS Max very quickly, using a Box With some noise for the terrain and then a few Chamfer Boxes for the rocks again with noise modifiers on.

Sim times were not so long due to the particle count been under 4 million particles, the core fluid and the Splash/Foam simulation took around 5 Hours . The Meshing took around 2 hours.

Rendering was done with V-Ray using a HDRI aswell as some V-Ray Lights for the Water Mesh. The Splash and Foam was rendered using Krakatoa and for the first time and after a some trying and failing I coloured the Particles via KCM/Magma Flow Colour by Velocity so when the particles are moving fast they are white but when they are slower they are more of a blueish watery colour.

V-Ray Water Shader was based on my Ocean Shader I developed for my Whale Jump Project (See the Fake White Water based within the shader)

Krakatoa KCM Setup

Comp'd in After Effects. 

FINAL SHOT

After some feedback I do agree that it is a little fast, this was due to me using directional gravity in Realflow to make the river flow from the emitter to the end of the stream where a KVolume Daemon kills off the particles. I think the value was a little to high. Next I am re working on a old shot and also doing RnD for a VFX Seqence. I have also just setup a new WEBSITE to look professional! 

Thanks For Looking!
