Hi all.
I right understand clipping in GUI work only on base pie/box node without texture? I mean if i place pie node with stencil and not apply texture for node it place mask on child node, but if i apply texture it doenst work?
I want make open gui with animated changed scale for child nodes.
I don’t understand what you want to do. Perhaps you could share a picture?

Ah, I see. I believe the transition that @JCash did was made using shaders. But if you want the use a GUI and use that GUI as an overlay/transition that masks anything beneath it then you need a pie node with clipping mode set to stencil and invert the clipping (checkbox). Next you need to add a box node with the texture as a child. This will punch a hole in the box node at the location of the pie node and show anything beneath it.
You mean make this structure:
pie node->first texture->second dexture?
You did not understand me. I want to make a stencil effect using a texture, that is, instead of a black area in place of a pie node, there was animation, and under it there was another object. I’ll do a little test project to show what I want.
So the texture image governs how it should clip? That is not possible with GUI stencils alone. You can do it with a render script that draws to the stencil buffer though.
I have animation sequence for every stencil step, when image change I need opened part of below texture.
OK, that sounds like you should use a render script that draws that texture to the stencil buffer and use it to draw the background.
I see you example for render script, but not full understand how it apply for GUI node 
It need special material for it?
Ah, yes, didn’t understand this. A custom render script is the solution.
