I am using ZBrush for something it’s not primarily made for - assembling an environment scene comprised of a couple of buildings. Obvioulsy this brings with it a scaling problem - the overall scene is too big for Zbrush, exceeding the preferred scale of 2 . At the same time certain details become to small. Is there a way to determine the best balance for scaling other than through trial and error ?
Hi @zzeebee ,
If you’re going to be working back and forth between ZBrush and another program, it is important to work out your scene scale pipeline before starting it.
When importing via traditional means (the Import button, not GoZ), as long as proper procedure is followed ZBrush will auto-scale and auto-center your model to work well in ZBrush, and record the values necessary to restore the mesh to its original size on export.
The trick here is always select the default polymesh 3d star as an import target when importing a mesh. The only reason for this is that is has zero values in the Tool> Export menu. In other words, it is a clean slate. If any other tool is active at the time of import, this tool may have its own settings unique to that tool in the Export menu, and the imported mesh will inherit these, leading to scale mismatch issues.
GoZ does not do this, however. It brings in meshes as is from the external program. So it is possible to bring in meshes that are drastically oversized or off-center for the ZBrush worldspace. GoZ may not be a good fit for your project if you are going to be working at that kind of scale.
If you have an entire scene, and importing the entire scene at the same time results in individual elements being too small when the entire scene is scaled to an XYZ of 2.0, then I would recommend working on those components individually, and not importing your entire scene at once into ZBrush. Remember, if imported correctly, the mesh will export out at the same scale , excepting any sculpting changes made to the form, and fit back into your scene seamlessly.
Good luck!
This is great information for in- and exporting. Now I am getting an idea why the star stays in a tool even when deleted.
Thanks so much Spyndel !
