I'm trying to add an RgbSpectrum to the emission channel of a Scattering Medium for a SSS material. However, when I tried to add the RgbSpectrum (or any shader) to the slot in attributes view, nothing appeared to happen. I opened the Node Editor to discover that the RgbTexture node was there, but not connected. Trying to connect it to the Emission port turns the wire red and refuses to connect it. I had a friend (who is also an Octane subscriber) try to recreate the problem, but everything worked fine for him. What am I doing wrong?
