Hi everyone
Whenever I go to the Render View tab to render my scene, and click on render, a Mantra node gets created automatically in the OUT network, and Houdini renders by default with Mantra. Is there a way to switch the default rendering in the Render View tab to always render with Karma?
Regards,
Antoine
How to select Karma as the Default Renderer?

The render view pane isn't really necessary with karma/LOPs rendering because you can just get karma to render directly into your 3D viewport.
Thanks for the reply. You mean through Solaris workspace? I was able to open Karma's Viewport on my other monitor; Whatever changes I make in the 3D Viewport, is directly made in the Karma Viewport on my other monitor... but I couldn't find a way to embed Karma in the default 3D Viewport; i am opting for an all-in-one realtime raytraced (karma) Viewport. Can I do that?

I suspect your "main" viewport is pointed inside a SOP or OBJ network? USD render delegates cannot be used to directly render into viewports pointed at SOP or OBJ networks, only LOP networks. If that is your workflow (mostly working in SOPs but wanting to see the final karma output) then you will need a separate karma viewport (or you can launch a clone and have access to the updating render in a render gallery pane - see https://www.sidefx.com/docs/houdini/ref/panes/clonecontrol.html [www.sidefx.com] for information about Houdini clones).
The reason we cannot use karma to render a SOP viewport is that SOP viewport interactivity requires a whole bunch of stuff that simply cannot be rendered by arbitrary USD render delegates like karma. The SOP viewport can show points, normals, arbitrary attributes, visualizations, and allows picking and interactivity that is just not possible unless Houdini's OpenGL/Vulkan renderer is in full control of the viewport.

jsmackThanks for the feedback jsmack. But then I have to export everything I done in the OBJ and SOP to USD, before importing in LOPnet?.. and in case I want to make changes to my Geometry, i'll have to export and import again? (or use SOP create/modify inside LOP... ?) which workflow is better and faster in Houdini 20.5?AntoinemrtamteYes tamte. But I was hoping there would be a way where the default Viewport showcases Karma's rendering. Like when in Maya we switch between Viewport 2.0 and Arnold in the same window.
if you are using Karma ROP, it has Karma Viewport Button
It does if you work in LOPs
