Hello,
Usually I use an HDRI image as environment texture to illuminate the scene, and of course usually I change the HPB rotation (in the environment texture node). All works good.
But if I add the node "Color correction Texture" (between the texture and the environment texture node), the rotation goes crazy: not only does the rotation no longer change, but the map also gets a rotation other than 0° (I can't understand how the map is rotated).
Is it possible to resolve this bug?

Thank you
Gianluca

This is a known limitation. The problem is that the environment node itself doesn't have these controls, so the plugin is using a hack to modify the incoming texture UV parameters, but this only works with the texture node connected directly to the environment node. Probably you can in any case modify the rotation directly in the texture node UV parameters, or adding a projection node to it.

Thanks,
