These other meshes are the &#8220;sources&#8221; of the weight copy.<\/p>\n<p>Please be aware that the tool only takes meshes into account when they have been rigged to the same Armature as the skirt! Any other objects are ignored.<\/p>\n<p>For the engineers: The weight copy function projects the weights from the source meshes to the target vertices.<\/p>\n<h4>The Copy weights Operator Panel<\/h4>\n<div class=\"row-fluid\">\n<div class=\"rhcol span7\">\n<p>As soon as you have clicked on the button, another box opens at the bottom of the Tool shelf. This is the <span style=\"color: #ff6600;\"><em>operator panel<\/em><\/span> for the just called Copy weights function, and you want to enable 3 options:<\/p>\n<ul>\n<li><em><span style=\"color: #ff6600;\">Interpolate<\/span><\/em>: for calculating a better approximation of the transferred weights.<\/li>\n<li><em><span style=\"color: #ff6600;\">Only selected Vertices<\/span><\/em>: If not selected then the tool copies weights to the entire mesh.<\/li>\n<li><span style=\"color: #ff6600;\"><em>Clean Targets:<\/em><\/span> Remove the weights for the selected verts before doing the Weight Copy<em><span style=\"color: #ff6600;\">(1)<\/span><\/em>.<\/li>\n<\/ul>\n<p>Now the 2 top edge loops of the skirt should move almost in the same way as the Avatar meshes do. In our case that is: the selected verts no longer move with the legs. You can verify this by scrubbing along the timeline.<\/p>\n<\/div>\n<div class=\"rhcol span5\">\n<p><a href=\"https:\/\/avalab.org\/avastar\/292\/wp-content\/uploads\/2020\/12\/Image1029.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft wp-image-6438 size-full\" src=\"https:\/\/avalab.org\/avastar\/292\/wp-content\/uploads\/2020\/12\/Image1029.png\" alt=\"\" width=\"406\" height=\"467\" srcset=\"https:\/\/avalab.org\/avastar\/292\/wp-content\/uploads\/2020\/12\/Image1029.png 406w, https:\/\/avalab.org\/avastar\/292\/wp-content\/uploads\/2020\/12\/Image1029-261x300.png 261w\" sizes=\"auto, (max-width: 406px) 100vw, 406px\" \/><\/a><\/p>\n<\/div>\n<\/div>\n<p>(1):If you select this option, then the tool cleans up the weight groups from any previously assigned weights. As a result your weight copy operates on a clean target. If you deselect the option, then weights are still copied, but all untouched verts keep their previous weights. You can use this when you do partial weight copies for different areas of your mesh.<\/p>\n<\/div><\/div>\n<h4>When all is set and done&#8230;<\/h4>\n<div class=\"row-fluid\">\n<div class=\"rhcol span7\">\n<p>The Weight Copy tool apparently has glued the skirt&#8217;s top edge loops to the avatar body as we wanted:<\/p>\n<p>However we realize quickly that fixing the 2 top edge loops gives us an ugly stepping in the 3rd edge loop. This becomes even more clear when we change the pose (for example by scrubbing our animation). But there is an easy fix for this, the Blend tool.<\/p>\n<\/div>\n<div class=\"rhcol span5\">\n<div id=\"attachment_21202\" style=\"width: 564px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/blog.machinimatrix.org\/wp-content\/uploads\/2012\/11\/blend.png\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-21202\" class=\"wp-image-21202 size-full\" src=\"http:\/\/blog.machinimatrix.org\/wp-content\/uploads\/2012\/11\/blend.png\" alt=\"blend\" width=\"554\" height=\"391\" \/><\/a><p id=\"caption-attachment-21202\" class=\"wp-caption-text\">After fixing the top edge loops, the next loop needs blending<\/p><\/div>\n<\/div>\n<\/div>\n<h4>Smoothing<\/h4>\n<div class=\"row-fluid\">\n<div class=\"rhcol span7\">\n<p>The Smooth tool is part of blender&#8217;s native weight tools.

You can switch to another weight group by clicking on its name in the Vertex weights Editor.<\/p>\n<p>&nbsp;<\/p>\n<h4>About weight pollution<\/h4>\n<p>You see that the selected vertex has 4 weights. And 2 of these weights are very close to 0 (mTorso and mHipLeft). While this is in most cases not a big problem, this can occasionally cause some headache because it may become possible that far away bones influence mesh areas just a bit. But sometimes they add small and occasionally even very strong visible distortions.<\/p>\n<p>Also with each additional Weight the mesh movement becomes much more complex and unpredictable. So it is in general a good idea to have as few weights as possible to avoid clutter of any form. And just in the case you do not yet know: SL supports no more than 4 weights on each vertex. It is not defined what SL does when you ignore this limitation. Although Avastar fixes this automatically for you during export of a rigged mesh, you should keep the control and keep this restriction in mind during your weighting.<br \/>\n<a name=\"1\"><\/a><\/p>\n<h4>Cleaning weights<\/h4>\n<div class=\"row-fluid\">\n<div class=\"rhcol span7\">In almost every case it is advisable to remove small value weights. You can do this by clicking on the white &#8220;X&#8221; on the right side of the weight entry. So, lets remove the weights for mTorso and the mHipleft&#8230;<\/div>\n<div class=\"rhcol span5\"><a href=\"https:\/\/avalab.org\/avastar\/292\/wp-content\/uploads\/2020\/12\/Image1040.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-full wp-image-6480\" src=\"https:\/\/avalab.org\/avastar\/292\/wp-content\/uploads\/2020\/12\/Image1040.png\" alt=\"\" width=\"549\" height=\"279\" srcset=\"https:\/\/avalab.org\/avastar\/292\/wp-content\/uploads\/2020\/12\/Image1040.png 549w, https:\/\/avalab.org\/avastar\/292\/wp-content\/uploads\/2020\/12\/Image1040-300x152.png 300w\" sizes=\"auto, (max-width: 549px) 100vw, 549px\" \/><\/a><\/div>\n<\/div>\n<p><strong><span style=\"color: #3366ff;\">Further reading:<\/span><\/strong> Blender has a manual and there you can find a lot more of information about its tools.
