3d coat auto retopo spline8/14/2023 ![]() ![]() Multiple uses for the effort put into making it. Use as a 3D object, or scale to flatten it for relief, convert to Rhino Nurbs, and flow along a surface.Additional advanced deformation techniques would permit numerous variations that would all still remain native T-splines and thus inherently watertight.Using Retopology to create a watertight T-splines asset would then bring about a laundry-list of benefits: Manually shade the sketch with the intention of using the grayscale drawing to roughly generate a heightfield mesh in Rhino.Use the freebie Sculptris software to sculpt the shape, then import into Rhino as an OBJ mesh.Sometimes done to emphasize & bolster certain topology features (crease build-up).Īn additional approach might be to obtain a quick & dirty mesh, then use T-splines’ retopology function to create a watertight asset. ![]() If you’re using T-splines in total beginner mode merely pushing/pulling a shape into submission, then there’s not much that can be done to help until there’s an understanding of various advanced techniques (pivot extrude, pivot scale, etc)Īdvanced users would probably make a habit of previsualizing where certain key splines need to be laid in. I have 3d coat 3.3.08 and I run this software on a Imac27 i7 8 gig ram.IMO, T-splines is being dismissed way too early. I check this video and and this not work for me. The wizard don't ask me to add reference curves or noting else. I follow this step and the wizard ask me only (Millions of polygones and normal smoothing) number after that I go automaticly in the repto section with the polygon object. I try to use guide line or strokes with quadragulate object. Hello sorry distub you, I'm a new user with 3d coat. Go to the Retopo Room to see and manipulate the result. Raise the slider amount back up for small areas like fingers.Ĭlick "Next" when you're done, and the rest is automatic. I suggest lowering the "spline points density" slider, (in top right menu bar), for long and large curves. So, after creating or importing something into the Voxel Room, right click on the Voxel layer in the Vox Tree where you want to run the AUTOPO algorithm and select "Quadrangulate object" - and the wizard begins it's magic, asking you, first, to estimate the total number of polygons you want to shoot for, (actual numbers may vary), and then to "shade" those areas of the sculpture you wish to contain the largest density of polygons.Īfter you have done this by left clicking to add dense areas and Ctrl-left clicking to erase them, you are asked to draw some reference curves which help the algorithm determine where to place edge loops. (Some people like the wizard, other's don't). In this example, a plane is used, but it could be any mesh, as youll see in the next step. Now, to invoke these functions, plus the function of defining which areas of the AUTOPO mesh are most dense, you open a kind of "wizard" that leads you through the process, step by step. Once you finish your 3D sculpt, use the following steps as the basic process for retopologizing: From Object mode, create a new mesh (Shift+AMeshPlane). These videos were made just prior to Siggraph, and were made with a prototype version of 3D-Coat, probably having no menu items. OK, not exactly but exactly so, here we have a problem that always causes artifacts. If so, zbrush autoretopo seems almost the same. If I choose to use auto-retopo then 1M or more mesh should expected. This way, I'll have some great details in zbrush, even using 30-100k meshes. Fine tuning in retopo room, thats what I like to do. Because I now know what details matter more what less. Its better to sculpt as more as I can in voxels room, then go for retopo. What's happening in the industry of VG is not my concern. Unfortunately!Īs a digital sculptor, I need some precise topology. Very difficult to have snap working using this method. IMO, all nice topologies with loops etc can be described as a simple tri model that is subdivided to quads. ![]() If the subject is an ancient sculpt then artifacts could look like aged marble texture. I could export a simple tri mesh directly from voxel room and do some more sculpture in zbrush. Because I know this way what details matter more what less. Lets say, I'll start some basic sculpture using voxels, then retopo, then to zbrush for fine sculpture. This is a good question, a great one IMO. Concerning this particular example of a non-animating model, why are neither triangles nor n-gons acceptable to you? Is there a particular problem that arises for you that is caused by the presence of triangles or n-gons? ![]()
