Question

High ram usage with 3D text?

Hi I have a Ryzen 1950x threadripper cpu with 32gb of ram and a solid state hardrive running windows 10 I just learned how to make a simple 3D text in after effects using an HDRI image to make the text shiny like metal but by the time I apply everything and try to animate it my ram usage spikes to 26gb and just stays there at first I thought it was because the composition setting is set to render timeline when idle so the green bar would always be updating as I made changes but after a while when everything was rendered out the 26gb of ram usage never goes down even when I leave the computer alone and just wait is this normal for a simple 3D text ? I understand after effects is a ram eater and needs a lot of it but I was just wondering if I have a memory leak or something else was up thanks in advance !

    Choose Composition > Composition Settings and check how much RAM is needed per frame immediately to the right of the Composition Resolution.  That plus the overhead of whatever you're doing in After Effects is how much data that After Effects needs to work with.  If there is not enough RAM to cache the frames, hopefully there is enough space on high speed storage media for the Media Cache.

    Hi so here's a snap shot of what it says is 31.6 mb per frame for this composition and when I scroll through the 12 seconds of the work area my ram usage spikes up from 4gb to 10 then 14 then so on and when I hit the numb pad 0 I get this error message as shown in the pic I'm using motion tile with my hdri image set the width and height to 500 each I was shown to do this in a YouTube video to get the hdri environment to cause the shiny ness of text

    You need to do what the dialog box in IMG_0431 indicates. It looks like your Layer Size is 20480-by-10240, but if your Comp Size is 20480-by-10240, that requires 800MB per frame.

    Did you look at the Compositiong Settings?
