Override default mtoa.mtd file

[jpmacey]

Hi All,

We have a number of machines that students use for Arnold (RHEL 7.5) and Maya 2018. The students do not have access to the mtoa.mtd file and occasionally need to edit them (for example to make the OSL node visible).

This is difficult to manage as students will use many machines etc so I was wondering if there is a way to override the default file and allow a local one to be read (perhaps by setting a flag in Maya.env)

Alternatively is there any scripting way to load aiOslShader and set the maya.hide option to false? As this will save our sys-admins loads of work.

Cheers

Jon

Sorry, but the metadata file has to be in the same folder as the mtoa plugin

The createNode command can create an aiOslShader node:

createNode "aiOslShader"

[jpmacey]

Tried that, it doesn't work

```

createNode "aiOslShader";

// Warning: line 1: Unrecognized node type 'aiOslShader'; preserving node information during this session. //

// Result: unknown2 //

createNode aiFlat; // Result: aiFlat1 //

```

guess I'm going to have to edit 200 mtd files!

I'm on Mac at the moment, not it is not there (unless I modify the mtd file to make maya.hide true ) then it appears and I can create etc.

I'm on 2.0.1 so that could be the issue.

Ok, with anything before MtoA 3.1.2 you won't be able to create an aiOslShader node with createNode

You have to change the metadata in the mtd file
