MaterialX nodes

[oglu]

Would it be possible to support Arnold matX nodes?
Like the aiRange node?

We tend to stick to the Standard nodes, not engine-specific ones. Is there a reason not to use Standard Surface and ND_range_color3?

[oglu]

no special reason. just a habit :d

What about the ND_geompropvalue node? I cant get the second uv channel working.

[hermit.crab]

Just tested this, in ND_geompropvalue, the first channel is named "st", second "st1", third "st2", etc.

Thats only the case in USD land. If you are in Maya you can name it how you want.

Yes, of course. But when you duplicate an object with, f.e, two channels with arbitrary names from Maya to USD, you need to use the USD land ones.

Tried to rename it to st2 also in the UV editor. Does not work in Vray.
Arnold does work with map2 and st2.

I get this warning. Maybe thats the main cause.
// Warning: line 1: V-Ray : MaterialX: Unsupported node type "ND_adsk_converter_float"
// Warning: line 1: V-Ray : MaterialX: Unsupported node type "ND_separate4_multioutput"


i dont use USD at all.

I tested it with V-Ray and it worked. But, yes, those two nodes are probably the reason.

I upload the scene somewhere. Maybe you have time to take a look.

PM sent. This is how it looks in Arnold.
