Questions about rendering weak textures or specular areas

[yjl010228]

Respect author, I'm looking for suggestions for weak textures or specular areas that reduced depth accuracy,resulting in a degraded view quality.For example, in the truck of tnt dataset, it does a good job although the truck scene has weak textures and specular areas.I guess the reason is that there is up to 251 images which makes the sparse point clouds more widely distributed and denser?And do you have any suggestions for improving the above issues?

You can try depth regularization, using monocular depth estimation，that can fix weak textures.And about specular areas ，I also want to know how to solve it.
