The pros and cons of using the bucket renderer versus Preview are discussed, and the new Nvidia Optix denoiser option in Modo 12.2 is also covered. The training has 3 complete step-by-step sections: firstly an interior lit with an HDR, then another interior lit with an area light, and finally a product shot. This should give you a comprehensive overview of the most common situations you can encounter while rendering in Modo.
The second step-by-step video also demonstrates a technique to speed up the GI calculations which can dramatically reduce render times for interior renderings, making them considerably faster, sometimes increasing render speeds by a factor of four or more.
Also the training teaches you to avoid certain combinations of settings which when used together can cause your render times to skyrocket.
The training also comes with a PDF that will help you identify and deal with the most common problems, this has been expanded since the original tutorial with additional information.
