    <description>&lt;P&gt;I know SYMB_MAT is the material for the override, but I am not sure if you can determine if the override is active or not.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;

      <title>GDL: Surface Override Parameter</title>
      <link>https://community.graphisoft.com/t5/GDL/GDL-Surface-Override-Parameter/m-p/385280#M379</link>
      <description>&lt;P&gt;Hi all,&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Is there some way to access and write back to the &lt;EM&gt;Surface Override Parameter&lt;/EM&gt;?&lt;/P&gt;
&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Lingwisyer_0-1687765750868.png" style="width: 400px;"&gt;&lt;img src="https://community.graphisoft.com/t5/image/serverpage/image-id/39552iCC5E37DC3BB865C0/image-size/medium?v=v2&amp;amp;px=400" role="button" title="Lingwisyer_0-1687765750868.png" alt="Lingwisyer_0-1687765750868.png" /&gt;&lt;/span&gt;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;I have ways to override surfaces within my object and I was wanting to link this parameter rather than have it be seperate and override the internal overrides.&lt;/P&gt;
&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Lingwisyer_1-1687765904321.png" style="width: 400px;"&gt;&lt;img src="https://community.graphisoft.com/t5/image/serverpage/image-id/39553i5AC175395E68B4D5/image-size/medium?v=v2&amp;amp;px=400" role="button" title="Lingwisyer_1-1687765904321.png" alt="Lingwisyer_1-1687765904321.png" /&gt;&lt;/span&gt;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;So the first internal override would be reflected to the external one. And ideally the toggle would be too.&lt;/P&gt;
&lt;LI-CODE lang="cpp"&gt;IF GLOB_MODPAR_NAME = "[gs_boverride]" then
	mat_over1 = [gs_boverride]
	mat_1 = [gs_override]
	PARAMETERS [gs_boverride] = [gs_boverride]
	PARAMETERS [gs_override] = [gs_override]
endIF

IF GLOB_MODPAR_NAME = "mat_over1" then
	[gs_boverride] = mat_over1
	[gs_override] = mat_1
	PARAMETERS mat_over1 = mat_over1
	PARAMETERS mat_1 = mat_1
endIF&lt;/LI-CODE&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Ling.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>
