view space behaviour on editor

[Inno]

Hello,

I try to create a simple matcap shader.
But I have some issue with the transform Tangent Space to View Space. It works fine on the material editor, but it’s weird on perspective view.
I rotate the camera all around a simple sphere, normally View Space representation must not move, but currently on editor we can see some rotation, view space seems to not follow my camera.

thanks in advance for your help.

I hope Chronichol doesn’t mind if I post this here for those who would like to try to play with matcaps.
Taken from this thread on Polycount -> http://www.polycount.com/forum/showthread.php?t=112129

Here is the result mixed from the polycount thread as a conviniet function so it can be easily reused for all sorts of effects besides emissive on unlit material. This is only the VAR version.

And that’s my result with this matcap when I orbit the camera :

Please tell me what’s wrong, thx
