It does not work when you restart the Preview render either. Only when you start to move the sliders while Preview is running.

It seems as if there's an issue with refering to the OSL file externally. Copying the code into Blender and using it internally works. So the error might be easier to find now.

Hey.

On OSL script was posted to randomize UV transformation which is supposed to work in the standalone version. It doesn't seem to work in Blender. I get a "No shader function defined" error. Maybe something to investigate.

Another issue related to this problem. Not a big one, but worth mentioning.

When the Preview is slowed down because of the "Baking Tex" node and I delete the "Baxing Tex" node while the Preview rendering is still running, the refreshing still stays slow although the "Baking Tex" node is completely ...

Hello.

When a "Baking Tex" node is in the scene, refreshing the Preview render is interrupted by "Upgrading Shader" pauses whenever something about the material is changed. Even if the change has nothing to do with the "Baking Tex" branch - even if the "Baking Tex" is not even connected.

Hey.

Sometimes I can't render any more and the message "ERROR! Check console for detailed message" appears at the top of the viewport.

I hope OTOY will use the fresh start to aim for an independant addon. Especially in the beginning, there will be a lot of fixes in 2.8 and Blender should be updatedable independant of the Octane addon.

To me this happens quite regularly (about every 15 minutes). But this may be because of the way my scenes are set up. I usually save the project and restart Blender. This works, but after several instances of starting the Preview Render, the issue appears again. All in all this is a bit annoying and ...
