I know it’s been a long time since this post, but I found another solution to this issue.
- Go to
Engine\Source\Runtime\D3D12RHI\Public\D3D12RHI.h
- Go to line 21, it should be
#define MAX_SRVS 64
by default - You may then change the 64 to whatever you wish. However, I would recommend 128 as it will be able to run on all hardware that can run DirectX 12. (Source)
Hope this helps someone
