Hi.
As the title suggests, how to rotate the HDRI?

Connect an octane transform node to the octaneImageTexture that the hdri is plugged into and translate in x

thanks TBFX , but I need to turn the hdri sphere in y. The y axis is blocked.

With octane, rotating the octaneSunSky sphere in the viewport doesn't affect the orientation of an HDRI so we need to use image texture transformations to achieve this. What I suggested above works as it effectively slides the HDRI around the sphere, in reality this is no different than rotating the sphere. If you really want to use a rotate workflow (admittedly it is a little more intuitive to work in degrees of rotation than 0 - 1 translation) you need to connect a spherical projection node to the projection slot of the image texture and then a transform node with rotation to the transform slot of the projection node, then you can rotate away to your hearts content in any axis you please.

perfect, thanks so much
