Resizing Virtual Texture Pools Problem

This keeps coming up and while rendering, my plugins are not visible. Could this be the reason? Also, why doesn’t LOD turn off while rendering? Objects appearing as you get closer is a very bad image for rendering.

Hi Talha,

Try disabling ‘Pool Auto Grow in Editor’

I try to increase the pool size without closing the notification, but it does not go away when I increase it. How can I increase the size of the pool and solve this problem? Textures go crazy when rendering. It goes back and forth. How can I fix this problem?

Cool Castle!

Are you seeing that ‘Texture Streaming Pool over Budget’ red text in the upper left of your screen in the editor viewport?

I know there is a console command you can try using to combat that. Also, monitor RAM and VRAM usage in the task manager (CTRL + SHIFT + ESC)

I used to see it, but now I don’t see it. It seems like it gets better even if I increase the texture pool budget, but I don’t think it works at all. How many times have I rendered the images and they are noisy? Since my graphics card was low, I decided not to push it too hard. In short, I couldn’t solve the problem :slight_smile:

I think i solved it.
To know the pool that needs more memory, i put this command: r.VT.Residency.Show 1
Then it showed dxt5 was on the memory limit. Then I increased the “Size in Megabyte” value to 250 and it was solved.
Now my video memory is exhausted, but all textures are in the correct form.

This will explain how to set your VT memory pool size.

But if you cannot fit all the textures on your card at once then you need to downres the textures. Which is what UE is doing for you. Otherwise the render would just crash.
