How to avoid flickering when switching images as rectangular materials

[chen21439]

I used preloading images and delayed deletion, but the flicker is still very noticeable. Is there any way to avoid flickering? For example, I noticed that when replacing the ImageLayer, there was no noticeable flicker

Hi @chen21439 ,

Thanks for your post.

I think the delay is caused by the new texturing being created. I believe this forums thread and linked issue discuss a similar problem Globe material flickers when updating - #4 by rlueders

A workaround may be possible. Can you tell us a little more about your use case how you are using rectangular materials with images loaded from an external source?

Thanks,
Luke

When we load tile maps, we also switch images frequently, but there is no obvious flickering effect. Can we solve this problem by modifying the image switching method? The requirement is to load images within a specified latitude and longitude range, usually rectangular

Thank you for your reply.

The link you provided is about a solution to the problem of flickering white edges when switching materials. I used image preloading to solve it, but there is still a problem now

The use case in Shahe Link is to load radar images and switch over time. I used two radar images alternately to simulate. even if the pixels of the two radar images are basically the same every time they switch, the human eye can still clearly perceive the switch

I use imageLayer, but it still has flickering. Is there a way to replace the image like loading a tile layer.
