ProBuilder BUG (weird cube shadows) and some questions regarding ProBuilder + ProGrids

    Hello everyone,
    I am using the Unity 2018.1.0f2 Personal version and I have some questions. I would also like to submit a ProBuilder bug.

    First of all, where are we supposed to download ProBuilder and ProGrids from? They are on both the asset store, but they are both also under Window>Package Manager. Which one should we be using? Is one of them obsolete or are they both the exact same thing? I have no idea which I should use.

    Secondly, I am using ProBuilder 3.0.8 (downloaded from the Package Manager), however it also happened with the ProBuilder I downloaded from the asset store. Whenever I build with cubes and such, I get weird shadows and things flashing on my cubes. Is anyone else getting this bug? It seems to happen the most when I move cubes around or make them bigger etc. I would like to know if this can somehow be fixed, because it is a bit annoying and sometimes the weird shadows persist when I am playing the game. Here are some images about the glitch in action.

    Lastly, I would like to ask a question about ProGrids. Is it possible to adjust the grid size to have rectangular grid cells, not only square ones? Is it possible to somehow make each grid cell for example 2x1 meters? Maybe it's possible to make a script that changes the grid cell size and does that? Basically, is it possible to assign a float value to one side of the grid cell and another float value to the other side of the grid cell? If so, how?

    Thank you!

    Hi Martin, welcome to the Unity forum! :)

    Downloading: definitely use the Package Manager. The Asset Store versions are for Unity 2017 and below.

    Flashing Shadows: those would be lightmaps rebuilding, nothing to worry about. If it's annoying or slowing down your work, I recommend opening the "Lighting" settings and disabling the "Realting Lighting" and "Mixed Lighting" checkboxes, while prototyping. That way you'll still get the benefits of "Auto" lighting (looks a bit nicer), but the slow light re-builds won't happen :)

    EDIT: the images with speckled/dotty lightmaps could indicate you have UV2 problems. You might need to try this fix:
    (let me know if that helps, if it does, we need to figure out why it happened for you)

    ProGrids: currently, there is only one Size value, but we've seen many requests to add per-axis values and we're looking into it, yep!
