Unreal 5.4 Movie render queue Virtual Shadow Map Problem

Development Rendering

Hey guys, I really do need help please :

The problem is that i need to use Virtual Shadow Maps for my scène because of my Nanite Ground (see the first screenshot).

In editor there is absolutely no problems, everything is fine as you can see in the first screenshot.

But, when I make a render, the virtual shadow map masks completely broke, i tried a lot of commands, i tried to force camera movement and light movement to force a refresh, but nothing work. (see the second screenshot).

Then I tried using the “good old” shadow maps, I forced a longer shadow drawing distance, and it almost fixed the problem, but, because of that old technology, I lost a lot of shadow details from the ground.

The 4th screenshot is a screenshot of my render settings.

Thanks in advance for your help, this is driving me crazy.

Just a quick update, using de Legacy Movie Render Queue, it’s seems to work fine, that’s a real non sence to me.
The bad news is that I’m pretty limited for the final image quality (I cannot use the AA settings from the “modern” Movie Render Queue), so I will probably render the sequence at a super high resolution (like 8k) and then downscale it to gain in clarity and temporal stability.

If anyone have any clue on how to make it work with the “Modern” movie render queue, I would be more than happy to know, to test something etc. Please feel free to respond and don’t consider this topic closed, this is not a solution, just a workaround.
