Hi Corentin,

First of all, welcome to Babylon!

It doesn’t look like there’s a feature built in specifically for doing exactly that. However, judging by [this `if` statement](https://github.com/BabylonJS/Babylon.js/blob/master/src/Materials/Textures/renderTargetTexture.ts#L802-L806), it looks like adding an observer to the render target texture’s `onClear` observable will cause the texture to not be cleared.

I tested this by going to the “Custom Render Targets” [example Playground](https://www.babylonjs-playground.com/#CJWDJR#1) and adding the following code on a new line at 62:

```auto
renderTarget.onClearObservable.add(()=>{});

```

I think this might work for your purpose. One caveat, though: this prevents the clearing of the depth buffer, too, so you’ll have to be mindful of that if the depth buffer will affect your future drawing.
