Hi, I had a similar issue and then realized that some optimization/default config had another “blur” algorithm selected which was overriding my selection.
Also, you might discover that DoF is too heavy for VR, and won’t give you the kind of results you’re seeking.
Had to explore this for a “dream sequence” in a project, and then realized that a simple fade-to-white or other post-processes were cheaper and were actually less jarring.
Hope that helps some,
