Peter Watje R6 Plugins:

Camera map Animated
http://www.max-realms.com/plugins/watje_r6/cameraMapAnimatedV6.zip

This modifier works exactly like the normal Camera Map modifier that ships with Max except that when the camera is animated the mapping is recomputed.

Chase Gravity
http://www.max-realms.com/plugins/watje_r6/chaseModV6.zip

Chase Gravity is a particle spacewarp which causes particles to chase the spacewarp or a designated object. It is useful for creating flocking type animations or using particles to outline an object.

CrossSection
http://www.max-realms.com/plugins/watje_r6/crossSectionObjectV6.zip

CrossSection Object is the object equivalent of the CrossSection Modifier. Basically you create a bunch of splines that you want to use as cross sections. You then create a CrossSection Object and press the Add button, which allows you to select the splines that you want to skin.

Deflector+
http://www.max-realms.com/plugins/watje_r6/deflectorPlusV6.zip

This is a rewrite of the original deflector spacewarp. It can pass through and affect stationary particles, supports friction and energy transfer.

Hair
http://www.max-realms.com/plugins/watje_r6/hairV6.zip

Hair is a particle system used to simulate hair. It was mainly aimed at doing long head hair but can also be used for short body hair. Since it is a particle system most particles space warps will work with it.

Gravity Plus
http://www.max-realms.com/plugins/watje_r6/gravityPlusV6.zip

Three different type of gravity mods.

InterpolateSpline
http://www.max-realms.com/plugins/watje_r6/interpolateSplineV6.zip>

Interpolate Spline allows you to set the steps of a spline, and change the optimization and adaptive settings after it has been collapsed.

Lag
http://www.max-realms.com/plugins/watje_r6/lagV6.zip

Lag is a modifier that stretches an object as it moves.

Linked XForm+
http://www.max-realms.com/plugins/watje_r6/linkedXFormV6.zip

This is basically a spiffed up version of the Linked Xform modifier. All bones in the system are equally weighted and have a radial influence from the center of the bone.

Mask
http://www.max-realms.com/plugins/watje_r6/maskV6.zip

Two plugins (Mask Top and Mask Bottom) that allow you to mask the effect of a modifier based on a bitmap or material.

MirrorTVs
http://www.max-realms.com/plugins/watje_r6/mirrorTVsV6.zip

This is a modifier that lets you mirror texture vertices, material ID's and smoothing groups across a mesh. Basically you select the faces that you want to mirror to and pass them to the modifier.

ObjectDeform http://www.max-realms.com/plugins/watje_r6/objectDeformV6.zip

This modifier lets you deform one object with another. Apply the Object Deform modifier to the object that you want to be deformed. Create another object and animate it cross the surface the object. Then pick that object as your deform object. This will allow you to do effects like footprints in the snow.

PaintMod
http://www.max-realms.com/plugins/watje_r6/paintModExV6.zip

This is a simple deformation system. With it you can choose an ink and brush and then deform the mesh by painting on it.

ParticlePlus
http://www.max-realms.com/plugins/watje_r6/particlePlusV6.zip

This is an update to the basic MAX Particle System. It adds a few more particle types, a few more emitter shapes, a particle position dump, and stream velocity and motion. Also contains Particle Material and Particle Blend Material.

Particle Control
http://www.max-realms.com/plugins/watje_r6/particleControlV6.zip

This is very similar to the Path Controller, except it follows a particle.

Particle Displace
http://www.max-realms.com/plugins/watje_r6/particleDisplaceV6.zip

This is plugin is a simple particle displacement modifier. Basically it works the same way as the regular displace modifier except instead of a gizmo a particle system is used to displace the object.

Particle Gravity
http://www.max-realms.com/plugins/watje_r6/particleGravityV6.zip

Particle Gravity just causes the particles in the system to attract or repel each other.

ParticleSpline
http://www.max-realms.com/plugins/watje_r6/particleSplineV6.zip

A spline object that uses a particle system as a reference. Basically it draws a spline between all the particles based on their age.
