Since the topic for 4.02 is locked I guess I will create a new bug report here.

I'm using Octane 4.02. I'm having trouble rendering a large image (6000x7200) with a denoise pass. With smaller resolution the image renders and saves the passes successfully but on this large resolution when the image ...

I'm running Fedora 29 Linux and I want to know if there is a way to scale the UI up because the text and menu items are very small in 4K resolution. Any suggestions?

I believe you also must increase the phong smoothing angle above 90 degrees.

Perhaps this guide from Inlifethrill would offer some insight to getting the look you are after.

I believe 3.07-Test3a supports R19. You will need to download it and probably delete all versions except for R19 from the plugin folder and copy that over.

Nice work! Does this mean we can now color particles by age/velocity?
