Hi there,
the VrayCarpaint material does not render the HDR reflections correctly, as you can see at the attached image. Can anyone help ?
Regards

Weird. It looks like the reflection is actually correct but that the HDR in the carpaint example is not filtered.
Same problem reported here: http://www.chaosgroup.com/forums/vbulletin/showthread.php?52551-Car-paint-bug-HDR-reflection-filtering&p=521646#post521646
Vlado said it’s a bug and they are working on fixing it.
I already read it, thanks. I wonder why only two people are complaining about such an obvious bug…

We are the most annoying ones 
I actually posted the same issue but I thought it was to do with motion blur.
It actually looks to me more like a normals issue with CAD data. You know if you get CAD data and put a normal modifier on it, the mesh loses its smooth quality and becomes faceted. Thats what it looks like to me, the material is causing the bug instead of the normal modifier.
Tbh it looks like a filtering issue, not anything with normals. The weird thing is that the unfiltered pixels are a different res than the rest of the reflected map, as you can see by the large unfiltered pixels aligned to the wall of the building in the reflected texture, and right beside it you can see the rest of the building filtered and at a higher resolution.
If it is Cad data try using a standard Vray material, flipping the normals, and seeing if you get a similar issue. Will show if it is what I think it is or not.
