Hey @SebHillaire, any luck reproducing the MRQ bug? I’ve been able to consistently repro on multiply machines. If Substrate & the Metahuman plugin are both enabled, you should see the errors when rendering with MRQ.
a potential fix/hack for the recompiling shaders is to modify line 165 of SlateElementPixelShader:
#if SUBSTRATE_ENABLED && defined(GetFrontSubstrateHeader)
This seems to be working for me so far, but I’m not totally confident this is safe. It would be great to get your thoughts. Thanks.
