Hello guys, I've made a rotating object ( flattened sphere with texture using a jpg) in Houdini
using a simple “$F” expression and exported via the ‘Film box fbx’ option.

when I import the fbx file in unreal engine, the following error throws up
“no smoothing group information was found in this fbx scene.
please make sure to enable export smoothing groups option”.

But the object got imported and we had to reapply the texture again in unreal.
The object is not rotating when we play. I'm new to unreal, and also new to exporting fbx object in houdini.
How do I get the animation to work properly in unreal?

Earlier, I brought in multiple objects as HDA but I didn't see the texture and the animation didn't work.
Can I bring in the animation through HDA?

Basically I want to bring the animation from Houdini to unreal, whichever way is best.
I appreciate any suggestions or solutions. Please help.
