Labs Flipbook doesn't render any textures of spreading fire

Hey, I have a simple fire-spreading setup:

spread_fire

I want to render it as a flipbook but it renders only a Normal map, neither Final Color, nor MDC etc.

Other Pyro setups render fine but I need a spreading fire as well.
Unfortunately I can’t upload hip files here, so here’s the link to sidefx’s forum to my Houdini project file.

Thank you!
