Hi,
We encountered an engine crash when a Skeletal Mesh with unlimited bone influences (bone influence limit set to 0) switches to a new SkinWeightProfile. It appears that the LookupVertexBuffer of the SkinWeightVertexBuffer is missing in this case.
Could you please confirm whether unlimited bone influences are currently unsupported for SkinWeightProfile? If so, are there any plans to support this feature in the future?
Thank you for your assistance. We look forward to your response.
Best regards,

Hi, yeah unfortunately, skin weight profiles with unlimited bone influences aren’t supported at the moment. We have an outstanding JIRA ticket for this, which you can find here. It’s not a trivial task to support this; we need to overhaul how the data is stored to do so, so I can’t offer any fixes or workarounds at the moment. However, I’ve reiterated to the dev team that this is still an issue and that you’ve run into it.
