Arnold Shader Custom AoV

• Add AoV parameter in [enum Zsjstandardparams]

Enum zsjstandardparams{... p_aov_spec_fresnel, P_aov_refl_fresnel, ...};

• Node parameter

Node_parameters {...   Aiparameterstr ("Aov_spec_fresnel", "Spec_fresnel");   Aiparameterstr ("Aov_refl_fresnel", "Refl_fresnel");    ...}; }

• Use a shader data struct-pass aov_name to shader

node_initialize{ shaderdata* data = new shaderdata;     Ainodesetlocaldata (node,data);}; node_finish{ if  (Ainodegetlocaldata (node))     {         ShaderData* data =  (shaderdata*)  ainodegetlocaldata (node);         ainodesetlocaldata (node, null);         delete data;    }};node_update{ ShaderData *data =  ( shaderdata*) ainodegetlocaldata (node);  data->aov_spec_fresnel = params[p_aov_spec_fresnel]. Str; data->aov_refl_fresnel = params[p_aov_refl_fresnel]. Str; aiaovregister (Data->aov_spec_fresnel.c_str (),  ai_type_rgb, ai_aov_blend_opacity);  Aiaovregister (Data->aov_refl_fresnel.c_str (),  ai_type_rgb, ai_aov_blend_opacity);}; Shader_evaluate{ shaderdata *data =  (shaderdata*) ainodegetlocaldata (node); ... if  (Sg->rt & ai_ray_camera )  {  aiaovsetrgb (Sg, data->aov_spec_fresnel.c_str (),  aicolor (Fresnel_spec));   aiaovsetrgb (Sg, data->aov_refl_fresnel.c_str (),  aicolor (FRESNEL_REFL));  }

• Edit MTD File:

[attr Aov_spec_fresnel] aov.type INT 0x05 default STRING "Spec_fresnel" aov.enable _composition BOOL TRUE [attr Aov_refl_fresnel] aov.type INT 0x05 default STRING "Refl_ Fresnel "Aov.enable_composition BOOL TRUE

• Edit Template file
