For example I´d like a really good collision detection for modelling. Maybe even a collision deformation (fingers deform, when they hold something). Not this tube-sphere thing.
The visibility of the data should be enhanced. Photoshop, Flash, they all have folders to organize their objects.
the buttons should have an option to wrap, if the width of the window isn´t big enough to display them all.
And a key (similar to the common tabkey) to jump from field to field (try to name 60 bones at once and you know what I mean).
I would like to fix objects (or a layer), so that they cannot be selected when I model. A commonplace option for other vector-oriented programs.
Then complete access to all the data via python. Especially bones.
An alignment option like ctrl-k in flash.
A more intelligent subdivide function for adding smooth edges and more control over the result (so more ways to restrict than ‘beauty’).
I would like an extrude-option inside the surface of a mesh, where you actually subdivide it, so that one does not create an independent new edge. For this tool, I´d like to have the ability to move the new vertex along the edge.
(bumpmaps that really deform the surface. I think it is called displacement mapping.)
I´d like to have more control over the armature-movement. It was possible to restrict the movement of ikas. This function seems to have gone or at least could be improved a lot.
Access to the absolute rotation of a parented object would be welcomed.
The constraint buttons could be easily enhanced.
When you model a joint with an armature, the vertices move to the rotational center, while bending the joint. Either a thing like ‘keep the distance to the center’ option or a direct link to a relative vertex-key would be nice.
This is my little wish-list (not complete)
the basic question is not, can you do it with blender, but how fast, how convenient can you do it?
