IES light orientation not working on light planes

[ciboulot]

Hi,

Is it normal that the Ies files orientation doesn't work with the light planes? It is impossible to make them face the right direction, like the direction in which the light is aiming.

Is there a solution?

Thanks

I had this problem too, but I was not sure if I was using the IES correctly.

Hi Richtoxic,

thanks for your answer. I did some tests with a huge library of IES. None of them work. I found out that it works with the spherical lights.
BUT, it was working before with the planes, so I don't understand why this doesn't work anymore. wIth so many other things, like the orientation of the HDR with the sun and sky node. (who would think of entering a value in the translate Z before the orient Y accepts to work in the transform 3D node?)
