A very useful function for surface details is the Boolean/Stencil
funciton.  Say you have a triangular image (one of those caution markers)
that you want mapped on the right shoulder.  Load the Image into Layout,
the go into Modeler.  Select it as the background image.  You'll probobly
have to tweak the size a bit -- try typing in the images resolution (say,
320x200) for the X and Y axis, which should give you a pretty good match.

Add a point to each corner of the triangle (do it clockwise) and hit p to
make a polygon.  Extrude it, so it had some depth, and rotated ti so it is
aligned to where you want it mapped onto the shoulder.  Mkae sure it's
partway through the shoulder, the Boolean Stencil.  Give it a new surface
named "Tri_Detail_X" (X is for reference in Layout, X axis).  Export the
whole object into layout (I forget, but you may want to do a merge points,
too.)

(BTW, If you have Pixel Pro, you can use that to make the "triangle" or
whatever -- it's a LOT easier than tracing...)

In layout, set the surface settings for the detail surface to be the same
as your whole Mecha's main surface (in this case, the shoulder).  Then, go
into the Color Texture Map panek, select the image, and autosize it along
the X axis (or whatever).  When you do a render, the image should fit
perfectly into the trianlular space, and leave no hint of black around the
edges (assuming your image is the EXACT size of the image file (meaning
you don't have a 10 pixel image in the center of a 320x200 screen --
you'll have to do a LOT of tweaking then...)

Also, there are Detail Polygons in Modeler, but those are rarely used
since Boolean Stencil appear.  Check Attach/Detach in the manual for info
on Detail Polys.

Hope this helps...
