Hallo Paul

Yesterday, I tried to open a library item however the assigned texture was not showing up.

It is possible that the location of the missing texture was moved so that the original path is no longer valid.
However, when looking at the obtained material in the rhino material editor, the note with the respective texture for example the diffuse slot, was just empty.

There have been no warnings or pop up messages indicating that octane doesn’t find any textures when opening the file.(I think I remember we had these messages in the past.)

Unfortunately, the path itself is also not showing in the octane material anywhere so I cannot easily identify the name of the texture.

I also remember that you modified the code long time ago due to my request to have standard search paths for textures. You gave me an example how to modify the config.xml file accordingly.

Unfortunately, this doesn’t seem to work either.

I have been busy with other things for a long time now so I’m not 100% sure that this problem occurred after the last version or maybe even before.

Can you do me a favour and create a quick scene in rhino:

1. assign a textured octane material to an element, save the scene

2.move the texture to a different folder and , open The scene and see if you get any pop-up message that the texture can’t be found.

3. Maybe you can also check if the syntax for the config.xml works when you point it to the new folder where the texture was moved to.

Thanks

Hi Andy - you are right - this is no longer working. I will need to look into this tomorrow. Will get back to you once I has some answers.

It looks like this error appeared in 2024.1.0.142. I have a new release of the plugin out tomorrow, which will include the fix for this.

Thanks

Paul

Wow - that was fast , thank you so much for looking into this!


Is there any chance to make the process of editing the config.xml a bit more user friendly?

Since you can have user defined standard search paths somewhere in the Rhino settings (I am travelling right now so I cannot lookup the exact location) I was thinking it might be possible to use these to define search paths for octane textures and maybe even orbx files …

If I’m not mistaken there is also a command in Rhino that list missing textures (check textures?) maybe this can be used as well?

This is an excellent idea, and should be quite easy to implement. I am releasing the Octane 2026.1 version of the plugin today, and then taking some leave. So I will implement this in January 2026.

Thanks

Hi Andreas. I have coded this functionality for you to test.

2026.1.0.147 - TEST VERSION
- Changed the process for finding missing texturemaps. Now missing texturemaps will be searched using Rhino's search path. Rhino will look in the following places: 1. Current model folder 2. Path specified in Tools->Options->Files->Search Paths list 3. Rhino system folders 4. Rhino executable folder

Hopefully this change does not break other users workflows.

Thank you so much for the effort Paul.

I will test it as soon a s possible.
