Hi, I think your saying menu is this addon. https://github.com/Yichen-Dou/OC-Blender-Helper-Addon By the way, I think octane for blender need material converter, and include baking texture. 3dsmax otoy's octane material converter could bake complex v-ray material and standard material as octane single image.
Sorry friends, Becaue of too many issues in my configuration I couldn't use Octane in that time but thanks for the replies, very helpful, I appreciate it.
