My "calculate weights" button is disappearing when I check "skin weights" (before you blame it on my bones or tell me to uncheck the unused influences box, please read further) Frivolous details: maya 2011x64 mac OS X 10.6.8 viewer 2 version 126.96.36.199864 OpenCOLLADA 1.3.0 plugin from here I HAVE unchecked the unused influences box in maya I HAVE checked all the bones with a text editor and compared them to a working mesh file.. they appear to be there in the .dae file I uploaded all the pictures from this post on a special flickr here Okay I seem to have the same problem as everyone else, but I swear I have tried everything. But, I still feel like in the end, this is going to be something small and stupid and I'm going to groan over whatever I am doing wrong. So here, I'm going to attempt to post my process with screen shots, and see if someone can tell me where I am going wrong. (because I've explained it like eight times, and two of the eight were only helpful in saying they had the same problem) My adventures in uploading mesh from maya to second life (it's been a roller coaster thrill ride)… Okay first off I have this pretty pretty princess dress (not really, I was just fooling around and testing mesh out) that I first formed from a nurb and then converted to polygons. I tried uploading the nurb straight and thought well maybe I can only use ploys for mesh… and that made no difference. <picture 01 - my mesh dress> okay so on I go, I import the Reed Steamroller skeleton from here And I did what Raster Teazle suggested here by adjusting the joint size to .05 and switching my coordinates to Z <Picture 02 - The post> So now my scene looks a little bit like ET: <Picture 03 - ET Dress with skelton> So I continue by switching to wireframe and clicking the hip bone on the skeleton so the whole thing appears white, and shift clicking the dress I've made. I follow the instructions he gives here… and do my smooth binding. Yes, I unchecked the remove unused influences box. <Picture 04 - my smooth bind settings> Kay so after that I select all and go to export all, double the work but just in case! I have tried both my OpenCOLLADA & my DAE_FBX exporter, and they both produce the exact same results…. <Picture 05 & Picture 06> my export settings I even tried using the dae_fbx exporter and changing the up axis to Z, but it gave me the same exact results… I haaaave heard rumors that the open collada exporter is buggy with certain versions of maya, and you have to uninstall it completely as it will override your settings to some degree, I wonder if this could be part of the problem. I have not tried that yet. But I was trying to export my mesh with dae_fbx before I knew everything and didn't have the opencollada exporter installed. Okay so next I log on to viewer 2, crash, relog, crash relog etc until I finally am able to log in and load and it doesn't tell me I have 20L… I do a mesh upload, and everything appears normal until I hit skin weight, then my calculate weights and fees button poofs! <Picture 07, Picture 08 & Picture 09> my upload settings for sl (no need to worry, I will take all the millions of linden I make off of this mesh dress and convert that to 20usd and put that towards buying a new computer!!) So like, I have fangaled with every lil button in there, even tried uploading my file to each lod and what not. And I can't figure out anything, the only thing that comes up funny for me and may possibly be a clue is this… When I click the funny lil settings icon, and I click show skin weights and show joint positions it comes up like this: <Picture 10> Uhh... wtf <Picture 11 - possibly the culprit> (everything I do gives me THIS same exact result) This leads me to think somehow rigging/skinning is not happening correctly in maya or my exporter is not behaving. I'm leaning towards the exporter, because when i wiggle around the joints in maya, they seem to behave just like that dudes video. But I don't really know, that's why I'm asking YOU! :) BTW the mesh is uploading in world completely fine, I just can't wear it. So I uploaded a non rigged version and it is mocking me with evil taunts, please help.
