No reports yet for the available releases.
Choose the 3ds Max version you use. For example, selecting 2020 puts direct matches for 2020 first, followed by listings that say a supported version or newer.
Scripts that only mention an older version can still appear as “2020 unconfirmed.” Listings that rule out 2020 are excluded. Use “Show scripts with unconfirmed compatibility” to also see listings without a clear match.
Community reports show what worked for members on a specific release. They’re separate from the listing’s compatibility claims and don’t change the filter.
