Has anyone had some decent success with datasmith from corona into UE4?
All the tutorials for datasmith seem to yield a lot nicer results from Vray than corona out of the box. Especially with regards to lighting.
Personally I've never been able to utilize datasmith properly for both renderers. But my scenes were not lightmap-bake friendly either, a lot of heavy organic elements with questionable normals.
Lighting wise, I've been always using quite high-resolution HDRI's along with dynamic lights, almost everything would be edited to reach the point we were happy with the outcome. Quality-wise (afaik) you won't get far without editing .ini settings, but it also depends on scene and mood.
