Object materials won't show up in final render

[mfersaoui]

Hello,
Object materials won't show up in final render even though it shows up in the render view. bellow is my code:

BaseObject* MyObject::GetVirtualObjects(BaseObject* op, HierarchyHelp* hh)
{
	if (!op)
		return BaseObject::Alloc(Onull);

	Bool bIsDirty = op->CheckCache(hh) || op->IsDirty(DIRTYFLAGS_DATA);

	if (!bIsDirty)
		return op->GetCache(hh);

	BaseObject* container = BaseObject::Alloc(Onull);
	if (!container)
		return BaseObject::Alloc(Onull);

	BaseObject* cube = BaseObject::Alloc(Ocube);
	if (!cube)
		return container;

	// create the texture tag
	TextureTag* const textureTag = static_cast<TextureTag*>(cube->MakeTag(Ttexture));
	if (textureTag == nullptr)
		return container;

	// apply material
	BaseDocument* doc = GetActiveDocument();
	BaseMaterial* material = doc->SearchMaterial("mat_name");

	if (!material)
		return container;

	textureTag->SetMaterial(material);

	cube->InsertUnder(container);
	container->Message(MSG_UPDATE);

	return domeContainer;
}

Bool MyObject::Message(GeListNode* node, Int32 type, void* data)
{
	switch (type)
	{
	case (MSG_MENUPREPARE):
	{
		Material* const material = Material::Alloc();
		if (material == nullptr)
			return maxon::OutOfMemoryError(MAXON_SOURCE_LOCATION);

		const Vector  color(0.85, 0.85, 0.85);

		material->SetParameter(DescID(MATERIAL_COLOR_COLOR), color, DESCFLAGS_SET_0);
		material->SetParameter(DescID(MATERIAL_USE_REFLECTION), Bool(false), DESCFLAGS_SET_0);

		material->SetName("mat_name");

		BaseDocument* doc = GetActiveDocument();
		doc->InsertMaterial(material);
		break;
	}

	}
	return SUPER::Message(node, type, data);
}

Hi,

you use GetActiveDocument() in a NodeData environment. You cannot do this, since nodes are also executed when their document is not the active document (while rendering for example - documents get cloned for rendering).

Hi,
I used the following and it is working.

BaseDocument* doc = op->GetDocument();

Thank you.

For more information about it, please read the BaseDocument Manual.
