Skinning on CPU or another mothod?

[Andy Gilbert]

Hi, im trying to load a mesh that has 2 bones with attached verts to them so i can find them and rotate them in LE.

 

Is the only way to do this by using the "skin" shader? I ask because when i do using my laptop with built in ATI graphics, the mesh dissapears without any error, i can only imagine this is due to the skinning being done on the GPU? Trouble is i use my laptop for most of my work and FPS wise LE runs fine at 30fps, just this skinning issue thats giving me headache.

 

Or is there another way to "find" a set of verts within a mesh and rotate them? I dont want to have them as seperate models as this seem inificenct and as there might be alot of similer models it would be difficult to organise them all.

 

Thanks

Andy

Ken is manipulating bones in this tutorial http://www.leadwerks...ks-tutorial-r83

 

no idea if this will work for you

 

EDIT: not really what you want I guess

 

There was an intel article about CPU Skinning here http://software.inte...ng-for-3d-games

 

unfortunately the attached source code is not available anymore

I suggest posting your model here. Otherwise we're all just guessing.

Its not the model josh, i can try any model that requires the "skin" shader, it dissapears?

 

remove the skin shader and it appears again, but can i manipulate bones and there attached verts without the skin shader?

maybe this is one part of the solution http://www.leadwerks...?f=32&t=4518��?

 

but vertex are probably not attached to bones .... their position is probably computed from closest bone and the info is in the GPU so you can't get it back, you'll probably have to play the bone animation manually. Big job.

 

Just curious, what's your ati hardware exactly ? AMD fusion ?

What exactly runs fine with 30fps... the editor without anything added? If so I wouldn't exactly call that fine.

Hi Scarlet , when i say "fine" im referring to just me editing levels and testing code sat on the sofa in my living room, as apposed to upstairs out the way in the little computer room.

 

WChris, not sure im at work at the moment but will check when i get back.
