RPC Tree Material Bluring

I have a bark material that seems to work well except as soon as the rendering has gone past building the light caches, and merging them, the tree becomes a bit blurred and the bark material also blurs the texture. Apparently I cannot upload vrmat here so I posted the material and the tree in my google drive folder. It’s so weird because it looks perfect right before the light caches merge.

Hi Julian,

Can you please upload the textures you used too?

Best,
