After hitting the animation playback button, you can how the cylinder gets badly distorted: At first, everything looks fine, however a click onto the cylinder reveals the completely displaced bone structure. You would expect C4D’s DAE 1.4 exporter to export ShiVa-compatible files. It has been set up with the usual guidelines, like a root bone at (0,0,0) that connects to the rest of the skeleton, no joint scaling, 60 fps animation target, etc: To give an example, here we have a rigged test cylinder in Cinema 4D R18. Without a clean and properly jointed import, ShiVa’s built-in TRS corrections will not help you much. You will be given the option to select what you wish to import in step two of the import process:Īnimation issues on the other hand are probably the hardest problem to solve. While it is possible to import models with animations, we often recommend keeping the model away from its animation track during the initial import and then importing the animation clips separately later. As far as textures go, you can attempt to let ShiVa search for the appropriate maps by their suffixes, however you will always have to manually adjust lighting parameters like specular and normal strength, so unless you have very simple models which do require little to no adjustments, we recommend not enabling textures and materials at import time and instead designing them separately. Size and orientation are the easiest: ShiVa offers checkboxes and inputs for both in the import dialogue. Problems with the model importer can usually be broken down into 3 areas: textures/materials, size/orientation, and distortion/animation. Fortunately, there is one tool which doubles as an excellent DAE/Collada file converter for ShiVa: Ultimate Unwrap 3D. While tools like Lightwave work flawlessly, others like Cinema 4D can give you major problems, especially when it comes to animated objects. However, it is also a rather flexible standard, and every vendor tends to implement it a little differently.
It is an open standard that has found wide adoption over the years in most DCC tools. ShiVa uses DAE 1.4 as its main model import format.
