arnold materialx bug?

[xtvjxk123456]

when i export matx use api

# coding:utf-8
import arnold
# arnold 6的api
arnold.AiBegin()
pp = r'C:\Users\Administrator\Desktop\look_c.ass'
u = arnold.AiUniverse
# 输出相应节点的数据
mesh = arnold.AiNodeLookUpByName(u, "/pHelix1/pHelixShape1")
shader = arnold.AiNodeGetPtr(mesh, "shader")
displace = arnold.AiNodeGetPtr(mesh, "disp_map")
arnold.AiMaterialxWriteMaterial(r"D:\test_matx.mtlx", "ccc", surface=shader, displacement=displace)
arnold.AiEnd()

i found test_matx.mtlx has some error.

diffuse_roughness is float in ass

and diffuse_roughness is color3 in mtlx file

there is the ass file.

look_c.ass

Yes, it comes out as color3 instead of float

But it still works when I apply the look with a MaterialX operator.

I don't know yet, I have to talk to the developer. Things are a little slower at the moment.
