Similar to Dreamscape or Terragen or Vue. Create dramatic animatable clouds that are compatable with iray / mentalray -inside 3ds Max. Cloud system to be part of the new intergrated physx simulation system. Terragen doesn't work in Max. Dreamscape doesn't work with iray / mentalray. Vue xStream doesn't work with iray and has it's own wind system.

It would be very good to have tool like maya sequencer in 3dsmax. Super tool for switching camera animation for shot

For photometrics I really need an option of choosing geometric objects as a light source :)
Self illumination in material is not good in mr.
For example this feature implemented in vray.

Actually i am working on stereoscopic 3d content development and have never found total satisfaction with tools currently available in Vray or Final render or Luis script for 3ds max stereoscopic camera modifier.

I personally want Autodesk to think in this section because it the most growing section at present and people are dieing to get something good.

The Autodesk Maya like tool or better then that one native inside 3Ds max will boost my production and may be boost Autodesk 3Ds max user community too.

A simple button next to the render settings in the render window itself that would send the render to the background and allow you to continue work on your scene, but not necessarily update itself - it would just take the scene as it is when you hit "render" and allow you to view that as you worked.

Please allow Screen Grid illuminance/luminance data to be exported to .csv files similar to Light Meter data to save having to type the data off the rendered image.

Sometimes we need to crop just some animated parts and would be geat if we could animate the crop in the viewport as we want it.

Have iray work with matte materials, shadow, reflections, etc, just like mental ray. If possible have iray work with some render elements, like Z-buffer, Matte, etc.

Ability to region render in max viewport like XSI.

A simple way to render with default lighting when there are lights already set up in the scene. It allows for quick test renders when scene lights aren't wanted.

Possible implementation: A radial box in the Render Window to switch between Scene Lights and Default Lights. This could also switch when changing the viewport setting: 'Illuminate With Scene Lights/Default Lights'.

Enable the ability to render just points (vertices) in Quicksilver to get similar results to Krakatoa when rendering particles.
The performance of Quicksilver is great, but if we are able to render just vertices then we can have 15 millions particles in a rendertime of about 1 minute per frame (more than Krakatoa, but is great if you don't have it).

Currently you can not do this, but it is incredibly useful, and opens up lots of new possibilities when creating imagery.

One of my only better favorited features in maya over max is the Render Layers feature in maya. Bringing that to max would be simply great! Managing heavy scenes for render would benfit in a big way.

GPUs are used in many apps now because of their speed. I think if Max was able to benefit from using the GPU as well, during the RTT process, or Mentral Ray, this would free up computers to do other tasks, as well as process the renders much faster.

Would it be possible (or even worthwhile) to configure the daylight system to switch to a "night sky system" when the sun is lower than the horizon?
