I load HDRI maps as the viewport background from time to time for preview purposes. The problem is that I get a seam running all the way vertically if I load the HDRI image via VrayHDRI map. Strangely, this doesn’t happen if I load the HDRI via the Bitmap map. The problem is only in the viewport. The seams don’t appear when rendering.
Please check the attached screenshot. Max 2016 SP3, Vray 3.30.03.
What type of mapping is this - spherical ? I can’t reproduce this… Can you share your settings and the HDRI itself ?
Yes, spherical mapping. No need to show settings and send HDRIs, I think. Everything is at default and it happens with every HDRI on 2 different workstations. Just start a new empty scene, make the viewport show the environment, choose a random equirectangular HDRI and load it in the environment slot with the VrayHDRI map in spherical mode. We’re using Nitrous display mode (DX11 level) if that helps.
Reproduced it, thanks.
The seam is caused by the Blur option on the Coordinates rollout. VRayHDRI does not support blurred spherical environment so as a workaround you could set Blur=0.01 to remove the seam.
Hm, I thought that enabling the tiling option in the texture should fix this… but if not, we should definitely make a note to look into it.
Best regards,

Noticed the seam renders with RT, but not with advance.
You are talking about RT GPU, right ?
Yes RT GPU
Thanks for the feedback, this is a known bug which is already reported into our system.
We’ll let you know when it is fixed.
