Hi Jim,

Thanks for the update on the OSL side I think is really needed, appreciate to keeping improving that.
I spoke with Haze about a fix on the standalone to make work in our workflow things on the Lua script was changed from OC 4.0.3 he said is fix, could we have a update engine soon his release the new engine please?

In that way we can update the full workflow here to 4 and then for next step later on, to 2019's

Cheers,
JO

Hi Jim,

Here a OSL script which a problem on the plug but not on the Standalone. the file path case for the link is showing on the standalone but not on the plug.
Please find attached here the file.

Code: Select all

// Proof of concept ImageTexture node for OctaneRender.
// Code that 'disables filtering' is based on a method from Image2Screen shader by Franois GASTALDO.
// sRGB response calculation is based on the OCIO python source codes by Haarm-Pieter Duiker.
// Feel free to reuse and adapt.
//
// Cheers

This is not a bug, but a user-error.
Please be sure you don't use in your script the names of already existing non-dynamic plugs of the OSL-node.
In your case the "File" input variable is conflicting with the existing permanent "File" attribute of the OSL-Texture node, so it gets not created as a dynamic attribute. Just change the name of this variable in your script to something else (e.g. to "FileInput"), and it will appear in AE as a dynamic attribute of a "string" type.
In next version I'll improve the UI for the string attributes, so that they will be presented as a file-path in AE (with a pick-file button)...

Hi Jim,

Okay I see, well would be great to work as Standalone so we can use the same OSL scripts without modified then for the plug only, I have multiple script on the standalone with the same file name and is working without errors? but not on standalone those script.

Cheers,
JO
