通过将X轴朝向,枢轴点位置连接到Rotate About Axis函数上,就能对物体进行旋转。同时通过FixRotateAboutAxisNormals函数将法线也进行旋转,如下图所示: 得到物体随时间绕X轴向旋转的效果: 多重旋转 如果要在上图小模型的绕X轴自转基础上,再加上绕世界空间的X轴旋转,也就是两重旋转效果,则需要使用两个Rotate About ...
首先:还是老规矩,新建一个材质球,改名字 把材质球丢到要实现旋转的扇叶 编辑材质球,我们主要就是要连线到全局位置偏移这个节点 它需要衔接到四个变量 在空白地方右键,出现搜索框 搜索RotateAboutAxis 再搜索ObjectOrientation 在OBJ的红块输出点,鼠标左键,拖出一个搜索框 搜索RotateVector 如图所示,连接起来 按着键...

置顶Rotate About Axis那个Axis可以直接Tranaform Vector,用Local to World,就可以将书页本地的轴变换到世界位置,这样就可以随便旋转这个系统翻页都不会有问题,而且也更直观一点。另外也可以试试全部用local space算顶点偏移,pivot就是0,axis就是书页本地翻转轴,location直接用local position,最后再对结果transform posi...
背景 如果要旋转颜色贴图和法线贴图的时候,单纯用CustomRotator旋转UV去采样,颜色贴图是没问题,法线贴图会有问题 正文 注意一下输入和输出FixRotateAboutAxisNormals的空间问题 上述例子是NRO贴图RG存了法线,解码出来是切线空间,所有有了Transform节点的转换,如果一直是世界空间的话,…阅读全文 赞同6 添加...
For some reason, when I import my FBX into UE5, it takes a very long time to import (Upwards of about 2-3 hours, assuming it doesn’t crash. Probably as there are 467 bones total in this creature and over 3,000 frames) and there is literally nothing the animation asset is doing....

Up is (Z+) * We stick to this convention to make it easy to reason about the coordinate system when constructing geometry procedurally. * After the panel is constructed, and modifiers like booleans are applied the panel is transformed and rotated into place on * the parent geometry (the ...
I'm currently working on a feature that would move rigid follower meshes in the way they should when morphs are applied in UE (e.g. buttons on a shirt move forwards and rotate slightly when the 'heavy' morph is applied). Additionally, some morphs change the regular joints transforms when...
