Can't get image displacement to work in ProRender 2.4 + Blender 2.83

Howdy,

I can't seem to displace a plane with an image texture in ProRender 2.4 using Blender 2.8x.  I've tried this across 2.8x versions and different computers / graphics cards.

My shader settings are attached as a PNG-- they work in Cycles (result attached) but ProRender either produces a flat, blank, grey plane with tiled rendering turned on, or exits with "ERROR | RPR ContextRender returned error code <-3>" with tiled rendering turned off.  Screenshots of both are attached.

 

I'm presuming there is something fundamental I'm missing: I'm using a 16-bit unsigned TIFF as a displacement map.  Does ProRender work with images as displacement maps and, if so, are there specifications for the files it can use?

 

Running this particular test on MacOS Catalina 10.15.5 with a Radeon RX Vega 64 via an eGPU, 8gb VRAM though I've gotten the same results across different systems with different hardware.


Thanks!
