So I am working on a few projects at the moment that involve zooming in to an extremely small point. I am getting close but I keep running into problems with adaptive subdivision.
There always seem to be moments when the subdivision pops into the next LOD level. I’m doing a render now to see if increasing the dicing rate to .25px will fix this but I would love there to be another solution because this adds insane render times… But my understanding is that it should be updating every single frame so why would there be clear lines?
This is how I see it behaving right now.
This is how I would like it to be.
Here are some tests where you can see it happening.
In this one please ignore the sand particles. I have figured out a way to make those transition in a much smoother way that makes the transition less obvious. But you can see before the sand spawns in there are very visible lines where the LOD is changing. The effect is really visible at 8-12 seconds before the sand comes in over it.
You can see it happen in this example too. It’s less obvious but I think that is because the camera is not travelling perpendicular to a plane. This is the one I am rendering out with a .25px dicing scale. I really hope there is a better solution to this than just cranking this value up really high.
If anyone has any ideas. I would appreciate your input.
