Type Maxwell Render tutorials (and/or training) in Google and then switch to Videos and there's lots done by various users including Next Limit which display for Youtube and Vimeo. Don't limit yourself to just recent videos as many were produced around v2 and v3. If you also type in Maxwell Render Vimeo there are other tutorials and Vimeo also allows you to download them to your PC.
Also, feel free to ask here - if there is no tutorial on your topic exist, maybe we could record one for you and for everyone else who might have similar questions.
we are quite friendly ... in most cases ))))) unless you ask which is the best software to work with Maxwell )))
Thank you. I will check the links you sent me first but more presisely I am looking for some information on lighting in interior renderings for interior design.
