I thought about that yesterday, “What if I’m making this and he doesn’t use Maya?” That’s funny and sorry I didn’t ask. Yeah the script is for Maya, you drop it into the script editor after your model is imported and selected. Then type ExtractAllBlendshapes() to run the script. I don’t think Daz Studio has the features you need for skinning, adjusting joints, adjusting uvs or extracting blendshapes. If you don’t use Maya though and have no plans to do so then yeah you’re right that Daz’s artist would be the best. The whole value of changing the skeletal structure for use in UE4 is to utilize retargeting along with the same animation blueprint and socket location structure on each character. But still it’s not necessary to do all this work.
