I'm driving nuts with other issue now <br>
<br>
I've created my UVs with<br>

only one plain color, same issue if I use a ImageTextureNode even if I set Tex->projection = ccl::NodeImageProjection::NODE_IMAGE_PROJ_BOX;</div>

<div dir="ltr">Hi,
<div><br>
</div>
<div>We don't have any example code for this specifically. It's easiest to create node with the corresponding class directly.
<div><br>
</div>
<font face="monospace, monospace">CheckerTextureNode *checker = new CheckerTextureNode();<br>
checker->color1 = make_float3(1.0f, 0.0f, 0.0f);<br>
checker->color2 = make_float3(0.0f, 0.0f, 1.0f);<br>
checker->scale = 1.0f;<br>
graph->add(checker);<br>
shader->set_graph(graph);</font>
<div><br>
</div>
<div>If you want to use the generic API, don't create your own <font face="monospace, monospace">
SocketType</font>, look it up in the node.</div>
<div><br>
</div>
<div><font face="monospace, monospace">const SocketType *color1 = snode->find_input(ustring("color1"));</font></div>
<div><font face="monospace, monospace">snode->set(*color1, make_float3(1.0f, 0.0f, 0.0f));</font></div>
