C Tech offers a new series of Free and Premium Video Training Classes which were produced on or after 2022 and therefore include the latest module naming (whereas the videos below used Pre-2022 EVS Legacy Module Names). These videos were created to assist users of all skill levels with using Earth Volumetric Studio.
The content of these classes is still relevant, but individuals using these classes must be aware that these were produced prior to the renaming of many EVS modules at the end of 2021. It will therefore be necessary to familiarize yourself with the old and new modules names (reference in the link above) to fully understand these videos.
All of the Earth Volumetric Studio training videos use data and applications that are included in the Studio Projects installer on C Tech’s Downloads page.
