But paying special attention to how your loops flow can help in some tricky situations.
For example, an elbow will naturally have edge loops that flow in the same axis as movement. In most cases, your topology will naturally align to the axis of animation. Aligning edge loops to the axis of animation can prevent faces from distorting and causing unwanted shading artifacts by ensuring that faces stay flat, even in extreme poses. With some practice, your topology may be able to work just as well when animated as it does when in a T-pose.įirst up, face alignment. So, with this in mind, I’ve prepared a few tips from my own experiences of modeling for animation. Accounting for this variability is not an easy task, especially if you’re not skilled in animation or used to working with characters. Organic, stretching surfaces such as skin require carefully crafted topology that deforms well in a wide range of poses. You just sculpted a new character concept, retopologized it, and added an armature…but then you move a bone and realize that your topology just doesn’t work as you’d hoped it would. Therefore to preserve the large faces and to smooth the smaller faces, keep the value very low.▪ #3d modeling #organic #topology #3d #blender #b3d The WeightedNormal modifier will make the split normals converge but their direction will take the face size into account: The higher the Weight value is, the more the large faces will weigh on the split normals. Here, the same cube, the left one with Shade Flat, the right one with Shade Smooth: If they converge they will tend to round the shading, if they diverge they will tend to flatten the shading. The split normals are the normals at each corner of the face that determine the shading between the faces. This modifier, like Shade Smooth or Auto-Smooth, will act on the split normals. With low-poly objects like this one you’ll have this kind of artefacts because Blender tries to smooth between these faces and Auto-Smooth won’t be able to fix it completely, it only takes the face angles into account.Ī good way to improve your shading is to use the WeightedNormal modifier in addition to the Auto-Smooth option.
