Hi Guy’s,
I was watching a tutorial where a character was being sculpted in dynamesh on a low resolution of 84 but he was still able to put detailed crease’s into his character without it looking blocky or low res.
When I tried to do the same thing it did look low res. Unfortunately I’m unable to contact the person to ask.
I’m quite new to Zbrush, would appreciate any thoughts or suggestions.
Hi @Dannyh ,
I can’t tell you with much confidence without knowing what you’re looking at. However it is possible they were using the Sculptris Pro feature on the brushes which adds geometry in real time to meshes. This would allow creation of greater detail in localized areas even on a mesh that is otherwise lower in resolution.
Not sure if any sculptris option was used as the tutorial is about 5 year’s old. Here’s a YouTube link to the tutorial it’s about 5 mins long but if you skip to 1:50 it will show you the dynamesh resolution settings & at 4:05 it will show the results of his low resolution sculpt.
His character isnt very sharp but the crease’s in his character are alot sharper than I’m getting with the same settings.
Ok, that user does a pretty good job of explaining their process. They actually aren’t using Dynamesh all that much. They are using IM brushes to add additional volumes as separate polygroups so that the individual meshes stay separate when the Dynamesh “Groups” option is active. This allows for some sharper divisions between forms since they are separate meshes that are merely intersecting, and not yet fused together.
Keep in mind the eventual polygon resolution is determined by the resolution and surface area of the mesh, but this is relative. A resolution setting of 80 on one mesh will not produce exactly the same polycount on another different mesh. A higher resolution setting reduces the size of the polygons, but the maximum polycount potential is determined by how much surface area the mesh occupies in the bounding box. So a cube that perfectly occupies the space in a bounding box will have a higher polycount potential than a long thin cylinder that occupies much less area. For most meshes this will probably cap out around 3-4 million polygons at max resolution setting.
Please note that as explained in the Dynamesh documentation that Dynamesh is intended as a tool to develop form up to about a medium level of detail. It is not intended for the capture of very fine detail, and it will be necessary to subdivide the mesh into a multi resolution form to achieve the greatest detail potential with the broader ZBrush toolset.
Appreciate that I thought I was using a IM brush aswell but I probably selected something similar. Will give it a try later. Thanks
