Render Texture

[megar34]

How can i save render texture as “.raw” image.
.
I suppose i need to convert render texture to byte array somehow but i dont know how.

Can you be more specific with your question, perhaps add a few details? What are you trying to accomplish? There are many formats that use .raw extension. Some digital cameras use that extension. Photoshop has a .raw image format too.

You can read texture from the GPU (your RenderTexture by using read pixels.) If you do a search for “convert rendertexture to texture2D” you will find many examples.

what details?

TEXTURE = new RenderTexture(TEX_WIDTH, TEX_HEIGHT, 0, RenderTextureFormat.ARGBFloat, RenderTextureReadWrite.Linear);
TEXTURE.enableRandomWrite = true;
TEXTURE.Create();
computeShader.SetTexture(0, “Result”, TEXTURE);
computeShader.Dispatch(0, TEX_WIDTH / 32, TEX_HEIGHT / 32, 1);
//need to save it as a .raw file
i dont want to convert it to texture2d its not a direct way

I don’t think there’s any other way than using the ReadPixels method of Texture2D if you want to get the texture data to CPU side from GPU. Then write that data as you wish. With details I mainly meant what are you trying to achieve, not what kind of code details you might have.

P.S. When posting code please use code tags.

i have a compute shader which calculates a mathematical function based on id.xy and i want to save this it as a raw file

It doesn’t really make difference what you are doing as long as the result is on the GPU side.
I would suggest you read a few threads on this topic before just telling me you “want” something. That’s not really constructive.

Here are a few useful links:

RenderTexture to Texture2D too slow?!

Turns out copying a rendertexture to a texture is a bit slow! With deep profiling it is just Texture2D.ReadPixels which is 10s of ms for a 1024x1024 in the editor. Seems other people have posted such, can you avoid read pixels and do it another way? Texture2D target renderTex = RenderTexture.GetTemporary( Width, Height, 0 ); cam.targetTexture = renderTex; cam.Render();//render stuff cam.targetTexture = null; //copy to Texture2D - slow bit!! RenderTexture.active = renderTex; target.ReadPixe…

How do I get the raw pixels of a RFloat RenderTexture on the CPU?

thanks maybe this will help
i want to store all data from the render texture in a bytes array on cpu
