Hi all, when using polypaint in 2020 there are some really frustrating glitches with polypaint. So for some reason say I have six sub divisions and I paint on sd 5 it doesn’t translate to 6. Whats more is when I go down the subdivisions the mesh fills in black! I can restore it by filling those subdivisions with white though it’s storing that polypaint data per subdivision which is really difficult to work with and I don’t want to be adding polypaint data to layers I dont need. Can anyone shed light on this? Is it a new function I can disable or something?
Hi @zenonithus
Polypaint your mesh at the highest level of subdivision. Don’t paint on multiple subdivision levels.
Polypaint is dependent on the mesh topology. If you alter the topology, you alter the polypaint. This includes changing subdivision levels. The topology you painted at sdiv 5 does not exist in the same way at lower or higher sdiv levels, so Zbrush has to approximate the vertex colors which will result in quality loss.
What is probably happening, is that you filled a mesh with a certain color/material at a lower subdivision level, and then switched to another active material/color. By default, Zbrush displays the actively selected color or material if no polypaint is assigned. When you paint at a lower level of subdivision , then switch to a higher one, it creates new polygons around the paint area that aren’t filled with polypaint, and displays the currently selected active color and material as a result.
I don’t recall this behavior ever being any different in Zbrush. I tested it in 4r8 to make sure.
Hi Spyndel, yeah I usually do that as the resolution is at it’s highest, though The poly paint is not carrying one down the chain of sibdivisions, instead the lower subdivisions are all turning black as soon as polypaint is applied to the highest. This is really bothering me as 2019 never did this and it makes viewing the model impossible to see what I am doing unless I polypaint the lower SD.
