I'm a beginner with Blender and may be missing something or just wrong. I'm an experienced professional product designer and have years experience with Rhino,Solidworks as well as Maxwell Render, Keyshot and Vray. I was interested in learning Mesh modelling to add to my skills during quarantine.

However, the values seem really screwy when I use real world values. For example I made a simple ceramic vessel and tried to use Subsurface values to make it look like porcelain. Because the physical object is small the values I need to use seem extremly low (subsurf 0.001 - 0.005). When I make an object massive, like 1000mm wide bowl for example I can use subsurf, and voronoi crackle effects with values that make sense in relation to the examples and tutorials i find online.

Basically what I'm curious about, Blenders funamental values are based on 1m. Does the physical size of an object have an impact on the Subsurface and texture values, or are these values relative to the object size. Eg if an object was 3mm thick the subsurface has a 0.1 effect on 3mm. Or would it be 0.1 on 1m(base units of system) meaning 10cm.... Sorry for ramble question.

  • $\begingroup$ Hi. Are you talking about Subsurface Scattering of the Subsurf (Subdivision Surface) modifier? Also, please make the title of your question specific to the problem you are having and not just the general topic. Thanks. $\endgroup$ – Ray Mairlot May 14 at 11:54
