Well I know why this is an experimental feature because it doesn't work AT ALL.
Seriously, KeyShot developers. Why is it so hard to include a two sided material?
Is there anyone who knows how to create a two sided surface in KeyShot 7?
I usually don't assume that anything is easy in coding, especially in 3D.
Experimental means just that. There's a reason its hidden, it may not work as expected. No need to get snarky about it. Since youa re new to the forums you are probably not aware that the developers of KS are actually extremely active on this forum and extraordinarily helpful, more so than any other 3d app I've ever used.
If you stop and think about it, how is the 2 sided material supposed to work? How does it know what is the inside and outside? How about a plane, which has no thickness and therefore is described as only 2 dimensional? Normals don't always cut it, they will point to the interior of a 3D object which is probably not what you are looking for if you are trying to texture a glass tumbler with thick walls. Normals can be edited, yes, but in KS it is all or none, you will have to do that In a 3rd party app. Not a huge deal to a small group that knows how to edit normals, not so for the majority of users of KS.
All this to say this- Just because you THINK it should be easy, doesn't mean it is. I have enough coding experience to know that 1) never assume anything when it comes to programming as to how easy/hard it is 2) I would not be a good programmer. Just a different way of thinking for those people. Hats off to them.
Maybe some manners and appeal for help rather than the attitude will bring the help of not only the KS people but the multitudes of other helpful artists out there. As for me, I just lost any interest in looking into it.
