View Direction is undefined?

Andrei Nadin hace 11 años • actualizado por Thibaud Troalen hace 7 años • 11
I am trying to use View Direction but no matter what I do , I get this error

Shader error in 'Custom/ViewDirProblem': Program 'vert', undefined variable "viewDirection" at line 190

It seems to be broken along with reflected

ah, now that you ask, it seems it might be user stupidity, :(

I am trying to do a shader where I increase the Y of a vert based in the grazing angle. So was looking to use View Direction to work out when the angle was low, perp the Vertex Offset between 0 and 0.5. If I plug View Direction into emission no errors but if I try and feed it into a series of nodes that ends up in Vertex Offset I get this problem.

Unless there is another way to solve this, I tried using the distance between view position and the world position but I need it very fine grained, it is for line markings on a sports field, The line is quite thin and I am trying to make it kind of 'curl' up in the distance to give me more pixels visible.

Yeah, vert offsetting is a bit messy when using some of the built-in vector. I will have to fix that down the line!

Plus I still get mul(UNITY_MATRIX_VP,..) instead of UnityObjectToClipPos(...).

Can you make a new thread with a clean repro case?

Thibaud Troalen hace 7 años

Alright, sorry for the delay.
