Hello, everyone!
I’ve wrote a shader that uses a Vector paramter passed from outside by script. It works perfectly in Editor, but when I’m trying to build it for iOS I get that error:
Shader error in ‘Custom/UI/UI - glow around point’: ‘Vector’ : syntax error syntax error at line 58 (on gles). Suprisingly, I can’t google any info on this - why is this occuring and how to fix it? Would appreciate if anyone could help!
line 58 reads the following:
uniform Vector _PointPosition;
Here’s the full shader code:
Shader "Custom/UI/UI - Glow around point"

_GlowDistance("Glow power (distance)", float) = 5
_GlowSpeed("Glow Speed", float) = 2
_GlowRadius("Glow attenuation (radius)", float) = 50
[Space(30)]
_StencilComp("Stencil Comparison", Float) = 8
_Stencil("Stencil ID", Float) = 0
_StencilOp("Stencil Operation", Float) = 0

_StencilReadMask("Stencil Read Mask", Float) = 255
_ColorMask("Color Mask", Float) = 15
