Hi
I'm newbie with Octane, i've just started to play with it. I have a question:
I made a material with bump and roughness based on the same image. I made a node to invert an image only in case of bump slot, but it is inverting this imaga in roughness slot too. I don't know what i made wrong with it. Help me please :)
Below I attached two screenshots showing this problem:

The invert input belongs to the image texture node. If you enable or disable it it will have an effect on all places where this node is used (in your case the bump and roughness slot). To invert the texture for only one input you can create a copy of the image texture (it will still be uploaded to the GPU only once) and disable the invert setting on one copy, or you can use an invert texture node as you have done. If you connect the image texture directly to the bump map slot then only the bump map will invert.
