I use Sketchtool to export layers. Sometimes the files have 1000's of layers that need exporting. When I ask sketchtool to export these layers, the memory usage goes through the roof even though the individual assets are small. I have tried to batch small amounts of layers at a time however this increases the export time dramatically because the file is large and complex and it seems Sketchtool is loading the file each time I call it. Is there something more I can do? Or will Sketchtool work as expected in low memory situations?
