thnx for comments, nice to hear this compliments.
watermark seems because that use a demo sdk

visibility tags has not direct support in octane side. But may be we can find a way to implement, it's very important for a professional.
if octane give me a option to supply compositing tags, i'll do. For ex. visible to camera is a basic but seriously important.
i wish to supply a workable demo and also beta version in a few week,
best regards
