I have installed rpr for houdini 19.383 the latest version and it matches my houdini version. I can get the render going in solaris but when i change any settings in the light there is no update even if i restart the render. I do get an error of "Device 0 not available (total number of devices -2018589406) at file C:\JN\WS\RadeonProImageProcessor_Build\src\RadeonImageFilters.cpp line 338" which is weird because thats not even a valid directory on my system. Materials seem to work well its just the lights, im running a gtx 1070.
