I can see situations, like the wood table’s top surface, where you don’t care about resolution in the planar geometry, but do care about resolution in the wood grain texture, might point to downscaling photos for reconstruction, then replacing the images with the original full res versions (same file names) for texturing, would zap the effect of grain. I’m still unclear why grain would factor in to begin with, given it’s random. Perhaps, it’s because the bumpiness is also random and based on however RC looks at grain and mistakenly determines certain grains per feature to be a common point of interest or feature. Generally, the actual features determine the basic shape of the table, then the grain creates a bunch of smaller scale errors that fall within a certain range.
