changing topology issue Tweet

When dissolving or drawing geometry on over time, the scene will render properly in the IPR on each frame. However when I try to render the animation range, if the rendering range starts on a frame where no points or primitives exist yet, from that point on, the frame renders completely empty. If I have multiple meshes inside one geo context with various material assignments and begin the batch render on a frame where at least one primitive exists in the scene, the geometry updates but the materials never get assigned... just the material of that first face for all others in the scene. MotionBlur is off globally. This used to work properly in previous versions (this is a pretty common need).

thanks,
Matt

Have you tried to render the scene in "full scene reload" mode? The problem can be that all the objects or materials not loaded in the first frame because they are empty or not assigned are not updated because, well, they don't exists in the Octane scene.

In these edge cases, the only workaround is to render the scene in full scene reload mode, at least until the frame where all the information is available in the Octane scene to let the plugin update it.
