Hello all.
Its come to my attention that Zbrush has its own scale which favours meters. Of the tutorials iv come across its recommended that in the Multi Map Exporter Scale settings are left at 1.
Now the models that I work on are real world scale, lets say a bust is 32cm. Assuming this is a new mesh loaded into Zbrush it should remain at 32cm. In some cases Zbrush seems to upscale the mesh, and change its export scale, im not sure in what cases this is, but it seems if it has a record from the past that the model was originally made at a larger scale.
In either case the scale setting of 1 for 32bit displacements do not work for me. When I check the scale of one such model that was used in a tutorial it measured 33 meters against my own bust of 33cm. I worked it out that this model where the displacement scale of 1 worked well at this scale, my model is 10 times smaller, so I put 10 as the scale. Low and behold the 32 bit map worked applying 10 both in Zbrush and as the displacement amount in Cinema 4D.
Can someone please elaborate what Zbrush world scale is based off, if, and when it scales models up, or down, and if my findings are a reality or not?
Also the Get scale, what is this doing, why use it, and how does one get the correct amount from this in the target application, in my case it came up as a scale of 26.
Thanks Dan
