Compilation Error Desktop Windows 64-bits : Maximum constant register index exceeded

Hi,

I made a shader that works on Editor and Android, but can´t compile for Windows 64-bits.

When compiling for desktop Windows 64-bits I get that maximum constant register index is exceeded.
I'm setting a global vector array of 150 elements. I'm also using a two global floats and a global int:

Shader.SetGlobalVectorArray("_MASK", m_mask);
Shader.SetGlobalFloat("_MASKLENGTH", j);
Shader.SetGlobalFloat("_MASK_R", m_radius);
Shader.SetGlobalInt("_MASK_PI_index", m_PI_j);

Where m_mask is Vector4[150].

I'm using shader globals to set the values once for multiple materials.

Is there a way to increase the number of constants that can be used?

These are the relevant logs:

Thanks

 

It's should not have this problem now, because of people were seldom using D3D9,D3D9 have such limit. Change it or use default D3D11, it will be ok
