Region render matrix: issue when resetting when "all tracks" option enabled

[ausbaxter]

Hey all,

Been trying to get a simple reset of the region render matrix to work. Handles master tracks (not shown) and individual tracks. However any region that has "all tracks" enabled will not reset using reaper.SetRegionRenderMatrix(). Looks like just a limitation of reaper.SetRegionRenderMatrix().

Anyone know how to get this to work? Thanks!

function GetRegions()--returns a table of regions in order to get real region indexes
    local marker_count = reaper.CountProjectMarkers(0)
    local region_table = {}
    for i = 0, marker_count do
        local _, isrgn, _, _, _, idx = reaper.EnumProjectMarkers(i)
        if isrgn then
            table.insert(region_table, idx)
        end
    end
    return region_table
end

function Main()--iterates through render matrix track indexes disabling tracks
    local t_regions  = GetRegions()
    for i, region_idx in pairs(t_regions) do
        local t = 0
        local t_temp_tracks = {}
        while reaper.EnumRegionRenderMatrix(0, region_idx, t) do
            t_temp_tracks[t]  = reaper.EnumRegionRenderMatrix(0, region_idx, t)
            t = t + 1
        end
        for i, track in pairs(t_temp_tracks) do
            reaper.SetRegionRenderMatrix(0, region_idx, track, -1)
        end
    end
end
