SOLVED Object materials won't show up in final render

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.

Cheers,
Maxime.
