[Closed] Show soft selection on unselected mesh?

Wait. Wait no, it doesn’t, sorry.

That colors the verts directly from red to blue, basically running the opposite direction on the color wheel.

polyop.setVertColor is very slow method (i’ve already explained why it is). if you need it faster use polyop.setmapvert instead

But doesn’t polyOp.setMapVert set UVW coordinates?

Also, still need a way to get the correct color…

so i meant:

		c = red
		c.h = red.h * weight + blue.h * (1.0 - weight)
		c

Currently using this with your makeWeightColor function, and it is working perfectly as far as I can tell. Thanks again!

fn vertColorFromSoftSel obj = (
	obj.showVertexColors = on
	obj.vertexColorsShaded = on

	for v = 1 to obj.numVerts do (
		local w = polyOp.getVDataValue obj 1 v
		polyop.setMapVert obj 0 v	((weightToColor w) as point4)
	)

	redrawViews()
)

All right, one last thing I guess… right now it still only works when the node is selected with subselection on. Otherwise polyOp.getVDataValue <node> 1 <vertex> always returns 1.0.

If I first select the node and lock the soft selection, then deselect the node, it will return the correct values. But is there any way to do this without having to select the node at all?

(weightToColor w) as point4

is not necessary. the function as you can see has an option argument.

about a sub-selection level… i think it’s a limitation. probably using sdk is possible to force soft-selection level update. with pure mxs is probably not. but just in case i would check the state of baseobject instead of polyobject. maybe it updates.

other way is to calculate ‘soft selection’ weights yourself. the formula is known. as i remember it was posted (by Klvnk?) on this forum

Not sure what you mean by calculate the soft selection weights?

far distance is lower weight. selection you know, neighbors you can find… distance as well.
the formula is something about distance, falloff, pinch, and bubble… it was shown here

Oh yeah, that. Unfortunately that won’t work if painted soft selection is on, which for my purposes it will be. Given that, not sure if this is the most efficient way to get the desired result, but it works.

fn vertColorFromSoftSel obj = (
	-- Store selection and subobject level
	sel = selection as array
	setCommandPanelTaskMode #modify
	SOL = subObjectLevel

	-- Temporarily set object and subselection
	select obj
	if subObjectLevel == 0 do subObjectLevel = 1

	-- Set mapping and display
	polyOp.setMapSupport obj 0 true
	obj.showVertexColors = true
	obj.vertexColorsShaded = true
	obj.useSoftSel = true

	-- Set vertex colors
	for v = 1 to obj.numVerts do (
		local w = polyOp.getVDataValue obj.baseObject 1 v
		polyop.setMapVert obj 0 v	(makeWeightColor w asRGB:on)
	)

	-- Restore selection and subobject level
	deselect selection
	select sel
	subObjectLevel = SOL

	redrawViews()
)
