I ran into exactly the same problem, but for 1.15.2; Not sure about 1.14.4, but by looking in RenderType I found the old fields, just renamed weirdly. In my case, RenderType.func_228643_e_() ended up being right; if you're using transparency, you'll probably want RenderType.func_228645_f_() . That is, in FMLClientSetupEvent, do RenderTypeLookup.setRenderLayer(block, RenderType.(whichever function you need))
