Hi,
I'm experimenting with a simple C++ plugin which draws a shaded cube using a locator node with a geometry override. The shading is done by loading a fragment XML from file.
If "Consolidate World" is enabled, and I start transforming the locator node (e.g. by translating it), the shader stops working.
After loading it looks like this (see the fragment XML below):
After starting to translate the node:
The strange thing is that if I replace the mayaChecker in the fragment XML to mayaBulge, this doesn't happen.
Some more details:
On the plugin side there is a locator node with a geometry override which builds a cube in populateGeometry, and in updateRenderItems it loads a fragment XML from file, gets an MShaderInstance from Maya and assigns it to the cube render item.
The code for the latter:
const char* frag_name = fragment_manager->addFragmentGraphFromFile("my_fragment.xml").asChar();
my_shader = shader_manager->getFragmentShader(frag_name, "outSurfaceFinal", true));
my_render_item->setShader(my_shader)
The fragment:
<fragment_graph name="TestFragment" ref="TestFragment" class="FragmentGraph" version="1.0">
<fragments>
<fragment_ref name="blinn_1" ref="mayaBlinnSurface" />
<fragment_ref name="checker_1mayaTextureOutputTooutColor1" ref="mayaTextureOutputTooutColor" />
<fragment_ref name="checker_1" ref="mayaChecker" />
</fragments>

</properties>
<values/>
<outputs>
<struct name="mayaSurfaceShaderOutput" ref="blinn_1.mayaSurfaceShaderOutput" />
</outputs>
</fragment_graph>
Please advise why is this happening and what can I do about it?
