(open) [HOU-4609] getattribute osl function

[matthias_buehler]

Is the `getattribute` osl function supported in VRay for Houdini? I am trying to use it to access uv sets, e.g., "uv", "uv2", "uv3" -> "uv8". But I can't get it to work.

Here is an example of how I am trying to use it:



In this example, `getattribute` can't find the geometry attribute and always returns 0.

I have tried "uv7" and "primvars:uv7". Any advice?

Otherwise if there are other methods to access uv sets in osl, I am welcome to suggestions!

Many thanks,
Jake

To be clear. I am specifically trying to access uv sets using OSL. I know there are VRay nodes that can do it, but I am specifically looking to do it using OSL.

Some more information:
I am using Houdini 20.5 with VRay 6.20.24.

Try using uppercase (e.g. UV7). If this won't work could you please us an example scene?

[matthias_buehler]

Hey Andrei, thanks for your suggestions, unfortunately it didn't work for me. I'm attaching an example scene where I try to access a geometry attribute. The TexUserScalar node finds the attribute just fine, but getattribute fails. I tried in obj and stage, but neither worked for me.

I tried uploading the hip file as an attachment, but it kept failing, I hope this link is okay: getattribute_example.hip

Many thanks

matthias_buehler sorry for the delay, the fix is currently under review, I hope it'll make its way into the builds this week.
