In all cases I have found, you can see a noticeable pop when switching from one LOD to another. This means that when the timescale is set to 0, there is no crossfading whatsoever and objects and LOD levels just pop in and out of existence. For all the mesh LODs other than the last (most crude) mesh LOD, the fade factor is calculated as the percentage of the object's current screen height, compared to the whole range of the LOD. The LOD Fade node outputs the level-of-detail fade value when using LODGroups.

Cross fade only sometimes work and not all the time. 3. 2 days ago · The only way I can get LOD crossfade to work at all, is to SWITCH OFF “Support LOD CrossFade” and then to add an ugly custom function node and custom subgraph + manually output to the alpha channel to do noise based crossfade (based on unity_LODFade. It’s the channel that gives images their transparency. My blue noise dither implementation is the exact same code (with a different number in the math for the differing dimensions), and a different texture. And they work as they should but I was wondering about a few things: using the fade instead of the dithering shader let’s me see the whole object including the 6 days ago · Perform cross-fade style blending between the current LOD and the next LOD if the distance to camera falls in the range specified by the LOD. 이렇게 전환효과로 발생하는 문제를 파핑이라고 한다.
