Hi Stompin. Thanks for dropping by. I can only speak for the beta version I’m using.
There’s no question that Vray is a lot faster, but perhaps not as realistic. I’m also still missing some controls over materials, but Andrey is working very hard on the script and it’s getting better everyday (literally everyday). There’s now support for diffuse transmitters, for instance (2-sided mats), which is great for interiors like those. Support for glass materials has even become much better since I rendered these images. Camera shift, render layers, etc.
What’s definitely harder to get than in Indigo are optical effects such as aperture diffraction and such. Well, you actually can’t get those straight out of the box and have to do them in post (I post-produced these images in Blender’s node system).
As for the workflow, well, it’s a question of what you’re used to, I guess. For Indigo, I always define my mats in Blendigo, never in Blender. Here you must define materials in Blender - not such a big difference. But apart from that, both Blendigo and Andrey’s script work very roughly the same way…
