2014.12.4 Fusion三维阴影完全看不清楚，完全不贴合模型，怎么解决？
先拿求助者提供的截图进行分析。一般都感觉贴图像素不够大，其实还有很多选项去直接影响这个阴影质量。
我做个简单的测试：其中要注意三维场景与灯光要保持一定距离，不能离得太远，会影响阴影贴图的质量。
Spotlight的阴影设置分辨率为2048，代理调为1。
渲染器中打开SS采样，开启HiQ按钮，就能看到更高质量的三维效果。（如果需要阴影做羽化效果，只能用软渲）

好像灯光离物体过近了，物体阴影会消失

如果觉得灯光大小的问题，可以放大场景来制作。还有灯光里的 影子bias 还原会如何呢 admin 发表于 2015-7-15 19:52 static/image/common/back.gif

如上图Multiplicative Bias已经设置为1，后面圆柱体的阴影偏移还是挺大的。若把圆柱体的半径改为1（原来的半径为0.1），灯光离物体很近时，物体投影也不会消失，但投影的偏移还是挺明显的 新XD 发表于 2015-7-15 23:07 static/image/common/back.gif

关键 默认 不是1，而是10. admin 发表于 2015-7-15 23:18 static/image/common/back.gif

把Multiplicative Bias设默认值10，那阴影偏移更大 新XD 发表于 2015-7-16 00:16 static/image/common/back.gif

要不你把comp通过附件传上来，我有空看下什么问题。 就只更改Density、Shadow map Size、Shadow map Proxy的值，其他的保持默认，才得到比较好的投影效果。前面立方体阴影的偏移也还可以接受吧。
