Hello,
I´ve just installed the latest hotfix for Corona 3, and it should enable support for 3dsMAX 2020 but it is not visible when I start 3dsMAX. In 3dsMAX 2019 version, Corona is available.
Does anyone else have the same problem?
I had a similar issue. I had to go into the settings in the installer and add Max 2020 to the selection. It was not selected by default.
