[Bf-cycles] Any sample on creating basic materials from scratch?

[Brecht Van Lommel]

Hi,

We don't have any example code for this specifically. It's easiest to
create node with the corresponding class directly.

CheckerTextureNode *checker = new CheckerTextureNode();
checker->color1 = make_float3(1.0f, 0.0f, 0.0f);
checker->color2 = make_float3(0.0f, 0.0f, 1.0f);
checker->scale = 1.0f;
graph->add(checker);
shader->set_graph(graph);

If you want to use the generic API, don't create your own SocketType, look
it up in the node.

const SocketType *color1 = snode->find_input(ustring("color1"));
snode->set(*color1, make_float3(1.0f, 0.0f, 0.0f));

Regards,
Brecht.
