thank you! Problem solved!

Thank you very much! Everything worked. While has remained visible border between textures. But it's likely that the problem is in the settings themselves textures and cubmapes

Thanks for the hint about Emmision. So looks beautiful!
And what about Negate, I, honestly, do not understand how to use it.
The node requires some kind of input parameter and output this to the DIR CubMap not connect.
Viewing the help (http://acegikmo.com/shaderforge/nodes/?search=Negate) didn't help.
Sorry for broken English.

I base on my experience . It in this issue , unfortunately, is not enough , so I can not explain why I think so. I thought that the mechanism of transformation from your structure to code, and back it mutually inverse linear function. As an option could be to try to enter the function: " Try to convert ? " And if the structure of the shader is not complicated , then disassemble , otherwise display a message : "Sorry! But i can't"
I think this feature would not be excessive , but once this issue has not been raised , I guess I was wrong. In any case, thank you for your answer!

for a very small usability? I do not think so.
Bought your product a couple of months ago and have already faced the necessity of such a functional. If you say so, but I think it is not so difficult and time-consuming. You are currently converting code nodes in the shader code. But if not, then nothing can be done.
