VRay to NUKE motion blur workflow

Here we create a teapot moving from left to right and right to left, move up and down, move backward and forward. In 3ds max, with V-Ray renderer, generate a color map represent 2D directional (vector) information, which we can use it in NUKE for motion blur effect.

In 3ds max 2011:

1. Add VRayVelocity element

Tutorial: random movement in thinkingParticles

Sometime we need to add some variation to our particles, however the standard Wind spacewrap is not very directable/controllable. Here I demonstrate three methods to add subtle movement to your particle. 1)using Blurbeta's random walk spacewrap 2)using A-bomb operator in tP 3) using Bubble Motion operator in tP

And finally, we combine those methods to create more complex particle motion. Have fun ; )

particle connected to three different forces. Turn on each of them to see the differences

Without any forces, particles look like this

With StdForce turn on (Blurbeta's random walk)

With A-bomb turn on

With Bubble Motion turn on

Tutorial: VRay gold material

Every now and then I was to asked create something made of gold. How to create a realistic gold material with V-Ray? Here is the quick setup:
