Insert Mesh Angle Alignment Reseting?

I wanted to have a long square bar (building beam) insert brush, with the intent of adding it as perfect horizontals and verticals, but I’m having trouble. I expected it to be perpendicular to the surface I draw it on but it often comes in at a strange angle. So for example I’m inserting a cube into the faces of another cube, holding down shift, and I expect all to be aligned with horizontals and verticals but it’s often not. I believe I narrowed down part of the explanation in the official docs:


  • In addition to inserting a mesh as a negative, holding ALT while inserting a model can also stretch it perpendicularly to the insertion. The mesh is inserted within the surface that it is being drawn upon.
  • >

Note: If after using the ALT modifier for drawing one object you continue to draw insertions of the same item, these additional insertions will keep the same transformation.

So with some tweaking and playing around I can sometimes get it back to be almost (but not quite precisely) horisontal/vertical. Plus in the process of trying that I often add aditional distortions to the shape which then get passed onto the next inserts. Do you by any chance know of a way to reset this behavior without restarting Zbrush? Or maybe some idea as to why sometimes it doesn’t even just change it’s angle from the vertical horizontal but actually stops being perpendicular to the object and instead is tilted as I insert it into say the faces of a cube holding down shift for snapping.

Thank you in advance for your help and patience.

my guess is that the surface you are inserting it onto is not completely flat, it’s catching slight surface angles when you pull it out thus distorting the angle at which it sits.


I might have doubts about that with my own surfaces, but this is a standard zbrush cube. The first couple of lines came in perpendicularly when pressing shift, but then I ended up with a strange random angle. They’re still paralel to eachother when i press shift, but they’re no longer perpendicular to the surface. I was hoping to use this insert brush to create vertical and horizontal beams but i can’t control them to keep a steady perpendicular/horizontal/vertical angle. Trying out that info from the standard docs I can change the angle but it’s very clumsy and I can’t reset it to default except by restarting Zbrush.

well i don’t know what’s going on with that. if you’re not stuck on having to use insert for all of them, you can insert one mesh, adjust it properly,
then ctrl+shift drag will pull out a duplicate. you may have to split it to a separate subtool.

yes, that’s the kind of things I ended up doing in the end because the normal/normal insetting didn’t work predictably, but it’s a shame, i wanted to use Zbrush for really fast concepting of urban type square shapes so I’m still hoping to one day figure out how to get it to work consistently.

Not to sure if this might be the cause of the problem… As Zeddie said you might need a flat face to project off.

Even if that would be the reason would still be nice to be able to solve it for quick urban concepting by insertion instead of duplicating subtools.

But even so, that only addresses the normal to the surface direction, and I have an analogous issue with the horizontals. Often they snap with shift not to the horizontal but to a 5-15 angle. I see maybe the same thing happened in your image to the right, all 3 cubes are snapped with horizontals paralel to eachother but not horizontal but ever so slightly tilted.

Hi iXaarii,

You problem has been bothering me, since your posting! I had the same problems in the beginning as you said in the first post.
Had a look under Brush Palette (switch off brush tilt under Modifiers) tried switching off Auto masking when using Insert Brush.
Tried a few different ways but I couldn’t get it to do it again? Maybe a Bug??? Contact support ???

But in saying that I did kind of manage to block out this scene in a few minutes.

Best of luck
