A licensee reported that the MipLevel sample mode doesn't work as expected with adaptive rvt.
Here is a sample project for reproducing.
1. open the project
2. open the "RVT_Landscape_Test" in "z_Test/Landscape" folder.
3. change the "Size of the virtual texture in tiles" to 11 or 12, the "RVT_Sample Normal_FixedNormal" actor should be black(sample the RVT), but it is red(sampled the SVT).
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-136254 in the post.
