I'm trying to export a model with an advanced flex controller to Source 2. When I change flex controllers to "Stereo" it works in Source2. However, a combination controller like something in the TF2 sample file won't work anymore. For example a provided sample controller like this:
"DmeCombinationInputControl"
{
"id" "elementid" "85d63542-afc1-4f41-8415-f81082ec8993"
"name" "string" "LipLoV"
"rawControlNames" "string_array"
[
"RaiseChin",
"OpenLowerLip"
]
"stereo" "bool" "1"
"eyelid" "bool" "0"
"wrinkleScales" "float_array"
[
"-0.75",
"0"
]
},
will result in Source 2 the "LipLOV" controller to be ignored and ModelDoc to generate controllers for RaiseChin and OpenLowerLip separately (without them being defined in the DMX file) that then control the flexes of the same name. Adding the:
"flexMax" "float" "1.0"
"flexMin" "float" "0.0"
to the control (as is auto generated) doesn't change this.

Lastly, corrective shapes won't export to Source 2 either.

Any way this could be address to allow export of flex controllers to Source2? Thanks for any advice/help.
