Count Sublayers in a layer

ASErr result = kNoErr;

try {

     AILayerHandle layer;

     result = sAILayer->GetNthLayer(layerIndex, &layer);

     aisdk::check_ai_error(result);

     ai::int32 count;

     result = sAIArtSet->CountArtSet(artSet, &count);

     int countSublayers = 0;

     // ignore first art, it is a layer art

     for ( ai::int32 i = 1; i < count; i++ )

     {

          sAIArtSet->IndexArtSet(artSet, i, &art);

          AIBoolean isLayerGroup;

          result = sAIArt->IsArtLayerGroup(art, &isLayerGroup);

          aisdk::check_ai_error(result);

Hello,

I've managed to solve it by using GetNextPreorderLayer function within AILayerSuite.

Thanks to all who have read it/or gave it a thought.
