回到母材质,给flipbook连入一个变量,取名random。在构造函数里,创建一个动态材质实例,然后存成变量,把source material也存成变量并暴露到外面(Instance Editable)。 在event tick里 set scalar parameter value,target就是刚才创建的动态材质,parameter name是我们在母材质里要改的值的name。我们使用random float in ra...

要想使用该功能,您需要启用WorldSettings(世界设置)->Lightmass settings(Lightmass设置)下的 'Use Ambient Occlusion(使用环境遮挡)' 和'Generate Ambient Occlusion Material Mask(生成环境遮挡材质蒙板)' 这两项,然后构建光照。 其它的类似MaxOcclusionDistance(最大遮挡距离)这样的环境遮挡控制可以用于调整外观效果。(请...
