Light texture not rendering in Specular channel

The lights in the scene with .exrs in the ‘Use Rect Texture’ are not showing up/rendering in the Specular channel.

Refreshing the link works in the IPR, but then on re-rendering the lights do not show up.
Reloading the links work in the IPR, but then not in the production renderer.

All lights without a texture render ok in the Specular.

I’ve tried .exr. and .hdr

Put in a standard V-Ray light and this has the same issue - shows in IPR, but not in render.

Everything seems to work fine on a simple scene. Could you please attach an example file and give us some steps to reproduce the issue?

Hi Zdravko

I’ve dropped on the beauty for the part I need, for now.
I’ll pm a file shortly.

Cheers
