The 3ds Max Updated Public roadmap at the Artist Experiences shows a new item called Brush tools. There is a brush tools panel that seems identical with Mudbox one. The details of this Future feature are not very enlightening: Consolidate and improve brush tools inside 3ds Max. The brush tools in 3ds Max are inconsistent.
Pls. better not be just a port of the Mudbox core like in Maya without all the power features of Mudbox like: Dynamic Tessellation, Sculpt layers, Ptex, Retopology etc.
Add a Preserve Volume option both to the Relax brush, Relax tool in Editable Poly like the previewed Relax modifier from the public roadmap.
Brush tools with physics and collisions like the recent developments in Blender (Cloth Brush) and Zbrush should not wait for too long either.
Same as those mesh filters and masking. The mesh filters in Blender are already cool and there can be only more of them and more powerfull soon. The Topology Automasking of the Sculpt tools in Blender is a simple, but very powerful option. The huge mask extraction options, are very useful and handly too, including extraction of mask selections making them solid in a single operation.
The radial Symmetry option as well from Blender works wonderful. And you can get more than a symmetry axis on at same time. That is not possible in Mudbox.
Max needs a robust set of sculpting tools, some actual sculpting tools would not be enough, especially now that Mudbox is discontinued and that sculpting is an ever more requested task from all industries.
Mihail Lupu wrote a small script based on the max functions (polyboost tools) combined with booleans and I can do this type of sculpt inside of 3dsmax.
