the tool like older plugin skinfx but with better colision tools

Currently, trajectories in 3ds Max are strictly for reference and do not allow the user to adjust the motion of an object. It would be nice if the trajectory could become a spline which you then could adjust in the viewport. This is funtionality similar to what is done in After Efffects or Combustion after a element is animated. Another example can be seen in Maya. There is a tech demo on the Area showing similar functionality.

Make a more robust fluid system where we can simulate photorealistic water, fire, and even smoke without the use of external plugins. Make sure it can be simulated fast and has general overall ease of use and speed unlike RealFlow 4 and even Fume FX.

Autodesk can look at guess what - Autodesk Maya for beginning:

Also BonesPro looks pretty cool:

- better performance, multi-threading
- modern/good/advanced skinning options
- better listener/filtering
- unified selections/tools between Skin and other modifiers (and stack)
- any innovation? (mix of displacement/skin morph/muscles and more)
- additional deformers?

For example:

Thanks.

Make the skin modifier better performance.

I would kill for something like Maya Dynamics inside of 3DS max. Any sort of half-decent particle simulations - water, smoke, fire, etc.

Even though it isn't a particle system, the awesome fractal pattern that Maya uses for oceans would be a huge plus in 3DS Max - the ocean (lume) shader only goes so far......

Bones Pro works with CAT and adds terrific volume preserving features and solving/feedback speed several orders of magnitude faster. It would turn Max into the solution to beat in terms of Rigging

Paul Neale's script will be such a great little addition. Even if its just added as part of the bonus disk.

Controllers can be assigned in the motionpanel and in the trackbar or a trackview. But not all are equal in editting the controller settings. In trackview you cannot set the rotation order for example, that needs to be done in motionpanel. You can assign a lookat to the gizmo of a xform, but after that it´s only editable via maxscript! Motionpanel only exposes controllers of transform(PRS) type. But lets you edit it, while trackview exposes all controllers, but doesn't let you edit it's settings (most of it).

Similar to Maya's dual quat. weighting or Eigen vectors.

Allowing CAT to use BIP files in Motion Mixer would be great. The current file type limitation in the motion mixer for CAT is a real limiting factor it its uptake for my current production.

Make assigning verticies/polygons/edges to bones easier and simpler.

The Cloth modifier is not multi-threaded. I recently had to simulate 16 flags blowing in the wind and when only 2 of your 8 cores are being used it can be really frustrating (it literally took over 8 hours).

There are probably other modifiers with this problem (Hair and Fur?) that could use an update.

Would be really good to have alembic point cache format support in max like it is in maya.

A rotation spring right now has to be built via dummies and offset transform springs, which is tedious and inefficient. Availability of a true rotation spring controller would be neat.

Cloth Fx in 3dsmax have many problem , too many Bugs , low speed, flickers and ...
i think

A tool/ Curve track that allows global or per track slow motion/time warp.

Rayfire's way is simple and effective - an helper with an animatable value. < 1 = slow down, >1 speed up. Put in a list the objects affected.
Should work with EVERYTHING - particles, noise phase etc.

Could be useful if we can put markers (like After Effects, for example) on the timeline.
One kind of marks for marking steps of the animation, or whatever.
And another kind for marks for indicate cropping area for render or playing.
There a place in Max, since version1, a free area zone at the right end of the timeline where you can place buttons, to choose to snap on them or not, or indicate to play only the playing-render time-zone.
