Re: How to set the default for a color parameter in a shaderdef?

I found the way in jscript after reading
thishttps://groups.google.com/forum/#!searchin/xsi_list/color$20parameter$20script/xsi_list/dUrC8i2mpb4/C_gQLRfzpicJ

var paramDef = params.AddParamDef(scattering_color,
siShaderDataTypeColor3, paramOptions);
var subParamDef = paramDef.SubParamDefs;
subParamDef.GetParamDefByName(red).DefaultValue = 0.2;
subParamDef.GetParamDefByName(green).DefaultValue = 0.4;
subParamDef.GetParamDefByName(blue).DefaultValue = 0.6;

 Hi folks.
 In a shaderdef define function, I can create a color param and set its
 default value to a mid gray by

  paramOptions = XSIFactory.CreateShaderParamDefOptions();
 paramOptions.SetDefaultValue(0.5);
 params.AddParamDef(color, siShaderDataTypeColor3, paramOptions);

  Any idea how to set each channel independently?

Hi,

i have something like this in my Shader-Definitions:

inputParameterOptions.SetDefaultValue([1, 1, 1])

Becouse it partly fits on this Topic:

Does anyone know how to set the Viewport-Mapping in a 
Python-ShaderDefinition?


In a SPDL-File you can set a it via
ui mapping

Is there a similar function for Python?

Re: How to set the default for a color parameter in a shaderdef?

2013-07-26 Thread Nicolas Burtnyk 
In C++ you do this to set the diffuse ui mapping (should be simple to port
this to python):

diffuseParamDef.GetAttributes().Set(L{8C80DEF3-1064-11d3-B0B7-00A0C982A112},
 L{3515CC72-082C-11D0-91DE-00A024C78EE3});

The GUID {8C80DEF3-1064-11d3-B0B7-00A0C982A112} means ui mapping.
The GUID {3515CC72-082C-11D0-91DE-00A024C78EE3} is the XSI GUID for
diffuse.

GUIDs for other shader parameters (like spec etc..) can be found by looking
at the ui mapping lines in material-phong.spdl.
