Hey Ron, you can easily do it with AtomKraft, even with the free version you can use SH and it is pretty fast :)
- Lay down an AtomEnvironment - Plug in your HDRI (if not latlong you can use SphericalTransform) - Set mode to "Accurate" for SH (spherical harmonics). Just FYI the "Approximate" stands for bent normals. If you also need real shadowing from the environment you can: - turn AENV shadows from "off" to "simple" to also have proper shadow from the HDRI environment (when using shadows you should use a proper sample count) If you instead just need plain environment occlusion : - connect another AENV with no texture plugged (default is white environment) and - set shadows to simple, and samples accordingly. Note that: * The relative AOVs are properly filled. * There are many other combinations (plain environment reflections, raytraced reflection of the environment according to the BRDF, multiple textures for diffuse & specular...) that you can achieve, we are planning a simplification of AENV along with presets as it is a bit overcomplicated for a comp artist.
