type mismatch (metal)

Tried converting the shader below in Unity 2018.1.2 and received this error -

Shader error in 'ShaderMan/Seascape': type mismatch at line 125 (on metal)

Compiling Vertex program Platform defines: UNITY_ENABLE_REFLECTION_BUFFERS UNITY_USE_DITHER_MASK_FOR_ALPHABLENDED_SHADOWS UNITY_PBS_USE_BRDF1 UNITY_SPECCUBE_BOX_PROJECTION UNITY_SPECCUBE_BLENDING UNITY_ENABLE_DETAIL_NORMALMAP SHADER_API_DESKTOP UNITY_COLORSPACE_GAMMA UNITY_LIGHT_PROBE_PROXY_VOLUME UNITY_LIGHTMAP_RGBM_ENCODING

Are there specific shader types that this works with?

Tried that on the default build mode in editor - Mac/Win

also tried converting to iOS - I suppose this isn't supported there yet?

Hi thanks for your feedback It's common problem and you can solve It easily change uv *= octave_m; to uv = mul(octave_m,uv); this is formula : A *= B to A = mul(B,A)
