[Resike]

Just a head up, in Power Auras i updated the Reset() method like this:

function model:GetBaseCameraTarget()
    local modelfile = self:GetModel()
    if modelfile and modelfile ~= "" then
        local tempmodel = CreateFrame("PlayerModel", nil, UIParent)
        tempmodel:SetModel(modelfile)
        tempmodel:SetCustomCamera(1)
        local x, y, z = tempmodel:GetCameraTarget()
        tempmodel:ClearModel()
        return x, y, z
    end
end
 
function model:Reset()
    local modelfile = self:GetModel()
    self:ClearModel()
    self:SetModel(modelfile)
    -- With model id
    --self:SetDisplayInfo(modelid)
    self:SetRotation(0)
    self:SetPosition(0, 0, 0)
    self:RefreshCamera()
    self:SetCustomCamera(1)
    if self:HasCustomCamera() then
        local x, y, z = self:GetCameraPosition()
        local tx, ty, tz = self:GetCameraTarget()
        self:SetCameraTarget(0, ty, tz)
        self:SetOrientation(math.sqrt(x * x + y * y + z * z), - math.atan(y / x), - math.atan(z / x))
    end
    --[[self:SetCustomCamera(1)
    self:SetCameraPosition(x, y, z)
    self:SetPosition(px, py, pz)
    self:SetRotation(rot)
    self:SetCameraTarget(0, ty, tz)
    self:SetOrientation(math.sqrt(x * x + y * y + z * z), - math.atan(y / x), - math.atan(z / x))]]
end

This solution was just a temporary hack:

self:SetCameraTarget(0, 0, pi / 5)
