Easy Way of Saving Render Textures as Pngs into File

warrencwwong · July 23, 2019, 9:57am

Hello! I am making a multiplayer shooting game, and each player could buy and use different guns. I have downloaded various gun models from the asset store, and I want to put images of the guns in different places(such as shop and player’s inventory).
To do this, I have used render textures to create images of those guns. But the problem is: I have 17 guns, and they have in total 700k verts, which is absolutely ridiculous(as I have to put the renders in all the scenes)! So I would like to ask if you know a way of converting render textures into pngs and saving them into the file. If you know how to do it, please give me precise instructions.
Any help would be deeply appreciated and many thanks in advanced!

Not really related to this forum, but you can have a look at this snippet:

DebugUtil.cs

public static class DebugUtil
{

    public static void DumpRenderTexture(RenderTexture rt, string pngOutPath)
    {
        var oldRT = RenderTexture.active;

        var tex = new Texture2D(rt.width, rt.height);
        RenderTexture.active = rt;
        tex.ReadPixels(new Rect(0, 0, rt.width, rt.height), 0, 0);

I am absolutely horrible at editor scripting, so please may you tell me how to do it? Thanks.
