Clouds can sort of work, if you then select each brick and rotate/flip to get back some seams. Though it might be simpler to just select a few bricks (unconnected ones) and run clouds, then select another few and again, until you've had all.
It's probably not disappearing, but shrinking down to where you can't see it. A good way to check this is to select everything that is still visible (Don't just marquee select an area- ctrl click on individual shells) and then invert the selection. Resetting your Xform usually fixes it-- in my experience.
Hmm, thank god they finally put soft selection in. Soft Modification tool was just about the worst implementation of a soft selection thing I've ever seen Multi-selection should be nice. Will have to see if we can get this update at work, should be useful.
More then likely the UV pieces need to be flipped. If you're using 3dsmax go into the UVEditor window, select face mode, click Select > Select Inverted Faces. Flip anything it highlights. If you used the mirror tool it inverts your UV's and they always need to be flipped.
problem is luke if you select each colour with the magic wand you get horrible ragged edges. is there a better way to select your colours and get clean edges like the alpha channel does? select by colour range still gives me slightly weird edges
manipPivot -p repositions the gizmo of your component selection in world space. xform -ws -piv repositions the gizmo of your object selection in world space. I don't think there's a way to move a shell selection to world space with a single command that also retains component spacing.
I use Modo, but maybe Maya has something similar. It has a useful edge selection tool called diagonal which selects the diagonals you need to remove to go back to a quads mesh. It's not perfect but it does a good 80% of the job, the selection needs to be adjusted by hand.
Looks like you've turned on soft selection. Double click the select (or translate/rotate/scale) tool on the left toolbar and in the tool settings palette uncheck soft selection. I'm not a regular Maya user so I don't know what the hotkey is, or if there even is one by default.
I do some interface work too, using layer effects sometimes. I made an Action for that does the Vig thing, works really well. New Layer Merge Duplicate Set selection Set channel Alpha1 to selection Delete layer Set selection to none
Without scripts: Extrude the border, select the newly extruded faces (ctrl-clicking the face level to convert selection from edge to face), switch back to edges and delete the selected loop for cleanup. Free script alternatives: Extend Surface (UI-less) Extend Borders (with UI)
