Render Texture - Creating and Changing

Hello,

I’m using 4 Render Textures to render a camera onto a 4 book pages.

Currently, the Render Textures are already created (before runtime) and are applied to the book pages. This works fine, but my Render Textures are 1024 x 1024 and I want to be able to lower that dynamically given the device that is running the App.

I first thought to dynamically building all the Render Textures and passing them onto the pages/cameras dynamically, but I can’t seem to get it to work as it looks like this:

This is what I’m doing to generate the RT:

//dynamically create render textures
renderA = new RenderTexture(256, 256, 16, RenderTextureFormat.ARGB32);
renderA.name = "RenderTest_A";
renderA.Create();
//renderA.active;

I then just thought I could already use the ones already built, and just change the width and height via code.

renderA.width = 256;
renderA.height = 256;

But that didn’t seem to work either, so whats the best way to do this?

Thanks.

Ahh, I’m a fool - I forgot to pass the RTs to my materials!

Works now!!

renderA = new RenderTexture(size, size, 16, RenderTextureFormat.ARGB32);
renderA.antiAliasing = 2;
renderA.name = "RT_A";
renderA.Create();
materialA.mainTexture = renderA;
