Virtual Shadow Map Error

[alpersapanci]

I get the error “Virtual shadow map page pool everflow detected”. What is the reason and solution for this? Thank you from now…

Hey there @alpersapanci! You can raise the VSM max physical pages, which means it will reserve more memory for itself.

First let’s check what it’s set at right now by running this command in the console:

r.Shadow.Virtual.MaxPhysicalPages

And then the output should tell you what you have now. Then we’re going over to your Project folder/Config/DefaultEngine.ini and then under the render settings area (create it if you don’t have one) then set it to a number that’s a power of 2. I use 8192 but you could use 4096 to test first.

[/Script/Engine.RendererSettings]
r.Shadow.Virtual.MaxPhysicalPages=8192

[alpersapanci]

I did what you said. I increased it to 8192 and checked it by typing “r.Shadow.Virtual.MaxPhysicalPages” on the command line. I saw the value 8192 there. Thank you for that.

But when I started my game, I got the same error again, but it lasted a few seconds and the game continued without any problems. Is this normal?

Seems like it’s still clipping high. If it’s not continuing to make the message it likely only goes over it for a while. Is there any artifacting afterwards or is it fine? Because you could raise the limit again but that’s a ton. Might be better to start doing some graphics profiling to see why your shadows are so heavy.
