Adding hotkeys to the image browser may not sound like a sexy feature but it would be extremely handy and speed up my workflow (use default windows hotkeys).

Alt+Up = Go up a level of folder hiearchy
Directional Arrows = Move around textures

Then add right click menu to directly apply texture as stencil, stamp or camera plane. Without needing to move mouse a long distance.

I have also mentioned in the past a right click menu for textures for such things as copy, cut, paste, duplicate, Show in Explorer (or Finder), properties, and finally an option to Duplicate and resize. Thus user can directly resample, resize image in Mudbox to another resolution without needing to jump to Photoshop. One more thing that would be great is being able to apply curves, levels, hue/saturation, sharpen, and blur to all textures within image browser. This could be done non-destructively or baked back down to the texture by the user (thus they could first use the duplicate image feature, then create some colour shifts, then bake them back down to duplicate).

The one other big feature currently missing for me regarding texture workflows is a method to warp textures before projecting.

mesh extraction with depth and edge smoothing. Do it the same as that other package that begins with Z. This would save a huge amount of time. I am tired of jumping between packages making base meshes.

Fix the move brush

Draw a straight line from point A to point B. Splines and stencils are not good enough at this simple task

Keep edge brush, smooth brush that works like z’s polish

Projection painting and modeling.

Ptex for colour work please. I could paint without worrying about uv’s and at later date transfer to my model that has final uv’s. This would be a bit like Z’s vertex painting but better.

Psd layer folders.

Paint layer masking. This has to be done the same as photoshop so it can be transferred between packages

Bake norrmal maps using smoothing groups.

Take it or leave it

I want ViewCube!
No, I’m not joking. Now with XSI joining the VC club it makes only sense that Mudbox should join also, but even more important is that Mudbox would benefit the most from VC. The other 3d apps had their viewports and stuff while in Mudbox is a struggle to switch between camera views.
