Hello,

I 've done a lot of research but I haven't found a answer yet. Working inside archicad plugin and using an HDRI picture as texture enviroment is it possible to rotate it ?

Hi - the manual explains how to do this. https://docs.otoy.com/ArchiCAD_Plugin_Manual_HTML5/ArchiCADPluginManual.htm#ArchiCAD/ArchiCAD_Plugin_Manual/Image%20Based%20Lighting.htm%3FTocPath%3DUsing%2520OctaneRender%2520for%2520ArchiCAD%7COctane%2520Daylight%252C%2520Emitters%2520and%2520ArchiCAD%2520IBL%7C_____3

That was fast, thank you.
It works.
For anyone has the same issue, HDRI should be rotated by sphere transformation and not by UV tranform as I did.

Hi Paul,
I and my colleges find the separation of UV and projection transform not so reasoned.
UV-Transform is always available even if you have another projection. UV-Transform should be under the Projection node.
It would be even better, if UV-Transform was grey, when the projection is not UV.

Best Regards

Hi David - I agree, however the Image node used for the IBL is a standard Octane Image node, that would usually be UV mapped onto geometry. Perhaps a better option would be to have an Image node which was just for IBL Images used for the Texture of a Texture Environment, which would not have the UV Transform pin. You could submit this to Otoy as a Feature Request if you feel strongly enough about it.
