Hey guys,
I was able to find a solution to this issue by reducing the weight influence of my bones. I use blender and found out that “weight” of the bones was causing the issue and giving me the message.
“Skeletal Mesh is not supported for current feature level ES2 and will not be rendered…HasExtraBoneInfluence=true”
Initially, I had weighted the bones by USING “Automatic Weights”. Since my character is simple, it worked fine.
It is weird as in previous engine versions the same skeletal mesh used to work fine at ES2.
Anyhow, I had to go do a little bit of weight reduction for my bones inside blender, it was not ideal but I still was able to do it through trial and error.
I exported my animations, deleted my old skeleton, reimported, checked if it is rendering and then reimported the animations and set them to the re-weighted skeleton.
In my case it was a spine bone near the shoulders causing the issue.
