Semantic_Segmentation for flow object in ISAAC SIM

Now, I am trying to use ISAAC SIM to generate synthetic data with segmentation masks, where flame (flow object) is considered as one of classes. However, I could generate the segmentation mask for all other objects except flow objects like flame.

Is generating segmentation masks for flow objects in ISAAC SIM supported currently?

similar question here, especially for the liquids.

Is the asset labeled? Do you have a minimal usd file with the asset to try out?
