Path Tracer problem when using WPO with Instances

Hey all,

I’ve been using the ue5 PathTracer for a while now and I’ve noticed a weird bug when I try to render a sequence. As you can see in the gif when the camera is moving the wpo on the instances (the plants are all instances) somewhy breaks. I’ve tried enabling the usual cVars (culling, eval. WPO…) but nothing seems to solve it.
I’ve tried with simpler meshes (a cube that rotates and warps with wpo) and the issues persists.
Is anyone aware of the issue and do you know if there’s a workaround?
Thanks.
