Hi everyone.

I'm having a problem with a shader I've created which gets various values from a BaseObject and converts them to colour values for the shader.

It works fine in the viewport (and renders fine there too) but it seems that the object doesn't get passed when I render to picture viewer.

This appears to be where it goes wrong:

  
INITRENDERRESULT MiscShaderPluginClass::InitRender(BaseShader* sh, const InitRenderStruct& irs)
{
	
    BaseContainer* dat = sh->GetDataInstance();
    
    target = dat->GetObjectLink(SDK_OBJECTLINK, GetActiveDocument()); // Gets the linked object
  
    if (!target)
	{
	GePrint("NO OBJECT FOUND")
	return INITRENDERRESULT_UNKNOWNERROR;
	} 
  
    else{
	"Do shader stuff"
	return INITRENDERRESULT_OK;
        }
}

I just get my NO OBJECT FOUND message.....
Does anyone know why this doesn't work?

Thanks,

Adam
(sorry about the slightly weird code formatting)

Probably the active document is not the same the one you are rendering (maybe a temp copy). Try passing sh->GetDocument() to GetObjectLink() instead of GetActiveDocument().

Amazing. Worked like a charm.

Thanks.
