As you can see, you can only work on the 8 vertices of the original cube for the left one but on the right cube you have access to the subdivision even if the modifier is not applied.Īlso, as Moonboots' comment states, you can also use DynTopo, it's an option in the tool settings when you are in sculpt mode and enabling it will make Blender to create automaticaly new hires geometry while you are working on sculpt mode : This picture shows you what I mean, the cube on the left has Subdiv Modifier and the one on the right has Multires both have a subdivision at level 2. Multires in the other hand allows you to work on you mesh non-destructively wich means you don't need to apply the modifier to sculpt on the subdivided version and you can increase or decrease the level of subdiv as you work. Subdivision Modifier is just used to subdivide your mesh and if you go to sculpt mode without applying it you will sculpt on the original unsubdivided mesh's vertices unless you choose to apply it but then your original mesh will be lost. Render is the level of subdiv that will be rendered.Īs I said in my comment, it does not work the same way as the Subdivision Surface Modifier. Sculpt is the level that will be affected by your sculpt mode and Level Viewport allows you to chose the level of subdiv that will be visible on the viewport.

You can add more resolution to your mesh by clicking on Subdivide.

There is a modifier that is made specifically for sculpting and it's called the Multiresolution Modifier : You should not (never) use that if your objective is sculpting but I think you know that now and you learned it the hard way. The Remesh Modifier is not supposed to be used for increasing the resolution of a mesh but, as the name suggests, it is used for generating a new topology for the mesh.
