a couple of workflow questions

I have a couple of models in development that i plan to rig and animate. With both of these i wish to create a model for animation and a model for rendering; I have done this previously and have encountered a few issues :confused:

This is the first…

I have reached the stage where I can either build a rig or continue with multires sculpting baking e.t.c.
I have a previously done this and had some issues with spikes appearing; i’m not too sure about using the multi res with an armature modifier. Current thoughts are to rig this as the animation dummy and then copy the mesh to work on further. But input from anyone would be useful.

The second model is this;

Its an experiment to rig the basic shapes of the model to easily weight the plates so they dont deform and then use this to animate. this is in progress.
Again i have some vague idea to copy the mesh and build a deformable skin that interpolates the weights already there.
There will also be mechanical details that will be objects
The end result aim is a high detail model.

I guess i’m interested in the most efficient approaches to rigging the dummy and the eventual renderable model so i can link both in a scene file.
Currently i am thinking that copying the weighted mesh and then continuing with producing more detail unwrapping / additional sculpting and texturing is the way to go.

If anyone has any ideas, inputs, suggestions e.t.c. (or warnings of major pitfalls) i’m all ears…
