Switch SOP Render Update

Mon Nov 23, 2020 2:18 pm

Hi there,

With a network like the one attached, where a switch sop is set to switch between render geometry, Octane does not update the material at rendertime if the ROP is set to Update Scene. It does work if you set it to Full Scene Reload, however this isn't an ideal workaround as Reloading the scene can often be unstable and adds time to the render.
Any tips?
Cheers

I'm afraid that this is not possible. If you switch the material at the SOP level you are going to need to reload the object, but now it is possible to reload one or more objects only even in scene update mode to avoid the full scene reloading. Have you tried that? You can configure the list of objects to be updated using the "Update Objects" parameter.

I see, thanks for the reply. Although this is the heaviest asset in my scene. Do you have a recommendation for another workaround for switching render geometries? I've tried animating the General Visibility parameter on the geo node, but that doesn't seem to work always.

I'm not sure. Perhaps using an attribute to switch the materials inside a master material? Any change at the SOP level means reloading to update the object, there is nothing that could help with that. You should try to avoid this switch at the SOP level.
