Fix my
export.

For a rigid accessory, choose its intended attachment bone in the IMVU Toolkit and run Setup Attachment on the accessory mesh. For clothing, use the clothing binding workflow instead.

Select the problem mesh. Check its Armature modifier targets the intended IMVU skeleton. In Object Data Properties → Vertex Groups, inspect the affected vertices: group names must match the intended deform bones, with weights assigned. An object name alone does not bind a mesh.

Include only the intended mesh and skeleton using your exporter’s documented workflow. Try the result on a default/reset avatar without other accessories first, then repeat on your intended avatar setup.

The current IMVU Blender Toolkit can export skeletal animation as XAF. If you use an FBX workflow, follow that workflow’s animation settings. Do not mix an old FBX preset with the Toolkit’s pose export instructions.

Play the intended frame range in Blender. For the Toolkit’s advanced animation workflow, check the intended NLA track under Control_Armature is enabled and competing tracks are disabled. Other exporters may require a selected Action; follow their documented selection rules.

An imported animation track still needs an IMVU Action/ensemble and trigger configured for playback. Test the trigger on a reset avatar with other poses and animations stopped before changing your Blender animation again.

In Weight Paint, examine the groups around the bad bend. Remove accidental influence from unrelated bones and assign any unweighted vertices. Compare neighbouring vertices before making broad changes.

Use Limit Total on the deform groups, then Normalize All as needed, checking locked groups. The current IMVU Toolkit documents six influences per vertex; older Classic guidance uses four. Match your actual target workflow rather than applying a universal preset.

Try bent knees, raised arms, sitting and a walk. Start with a default/reset avatar to isolate the asset, then test the body and scalers you intend to support. Do not apply all transforms to an already bound rig as a blind fix.

Export mesh through an SL-compatible COLLADA (.dae) workflow. Check required joint names and hierarchy, unsupported negative scales and a maximum of four bone influences per vertex. Do not rename an FBX file to .dae.

Preview skin weights in the uploader and enable Include skin weights for rigged clothing. Include joint positions only if you intentionally authored joint offsets; it is not a general repair switch.

A rigged mesh follows its weighted skeleton, regardless of the selected attachment point. Fix the rig/bind setup rather than trying different attachment points. Test on a reset avatar, then the intended mesh body and shape.

Use a Second Life-compatible animation workflow, such as BVH. The mesh uploader and an IMVU FBX/XAF export do not replace the SL animation upload process.

For BVH, the first frame is a reference frame, not the visible pose. Verify the intended bones actually change after that reference, and preview the exported clip before uploading.

Temporarily stop your AO and other animations, then play the test locally. Review priority, loop and ease settings in the animation preview. Use the priority your action needs rather than raising every animation indiscriminately.

Use the intended body’s authorised creator reference and a compatible rig. A successful test on the default avatar does not establish compatibility with every mesh body or shape.

Check for stray or missing weights and smooth transitions carefully. Keep SL’s four-influence limit. For fitted mesh, collision-volume bone weights affect shape response, so do not replace them indiscriminately with ordinary limb weights.

Try walking, sitting, raised arms and representative shape changes on each body you claim to support. An appropriate body alpha may hide covered skin, but it will not repair a distorted garment or guarantee fit.
