MaterialX Exporter

[Rikdelausnay3YM95]

I've been playing with the new MaterialX exporter of arnold.
At the moment he only exports the shaders and the assignment to the geo.
The geometry parameters like fe. subdiv type, iterations,... are not exported with it.
Is this because it's still quite a new utility or am i missing something?

Cheers,

Rik

You have to enter other parameters like subdiv_type and subdiv_iterations in the Properties box.

Then you get

  <propertyset name="pPlaneShape1_test_propertyset">
    <property name="subdiv_type" value="catclark" type="string" />
    <property name="subdiv_iterations" value="2" type="integer" />
  </propertyset>

I just hoped it would do it automatically with the exporter, because the assignment with the setparameter operator is the same as the shaders.

But this works as well, thanks!

After reading all the docs of the exporter i came across this:

Properties

Additional shape parameters to export. For example, step_size and volume_padding for a polymesh that is rendered as a volume.

The following shape parameters are automatically exported (if they are set to non-default values):

• visibility
• sidedness
• disp_padding
• disp_height
• disp_zero_value
• disp_autobump
• autobump_visibility

Is there a way i can edit the current exporter so I can implement all the other properties to be written out as well?

in a past life i did some C++ programming so im able to do some coding but I can't find my way yet in the arnold files.
