How to create a texture from file or buffer? Can URP RenderFeature or CommondBuffer used in Tiny?

How can I create a texture from file or buffer in Tiny?
Like Resource.Load<Texture>("file://") in legacy Unity project.

How can I render this texture in scene?
If I want to use this texture as background of my camera, is it possible?
(As using commondbuffer to change the render background in legacy Unity project).

How can I load resources from disk or cloud?(As I know, tiny doesn't support AssetBundle.)

 

You can't use anything from UnityEngine namespace in Tiny, namely CommandBuffer.
I think your best option right now is to create a sprite in you scene and use it as a background and from there on you can load external textures to it.
I load texture like this:

Code (CSharp):

1.     public static Entity CreateTexture(EntityManager em, string path, string name = default) {
2.       var entity = em.CreateEntity(typeof(Image2D), typeof(Image2DLoadFromFile));
3. #if UNITY_EDITOR
4.       if(!string.IsNullOrEmpty(name))
5.         em.SetName(entity, name);
6. #endif
7.       em.AddBuffer<Image2DLoadFromFileImageFile>(entity);
8.       em.SetBufferFromString<Image2DLoadFromFileImageFile>(entity, path);
9.       return entity;
10.     }

You can then replace the texture entity of the background sprite (Unity.Tiny.Sprite).

 

Thanks for your reply.
What format should the path be?
local files: D://A/B/C/a.png ? or file:///D:/A/B/C/a.png?
web files: https://a.b.com/a.png
I have tried these, but none of them works.

Can I load a image from a native array or pointer?

One more thing, how to see log in Windows-DotNet building?

 

For full path:

Code (CSharp):

1. c:\\images\\myimage.png

if you place the files inside the root of your build and use a relative path

Code (CSharp):

1. images\\myimage.png

 

Thank you for you quick reply.

You have to read the raw data into Image2DMemorySource and create an Image2D representing that data.
I haven't loaded textures using this method but you can look at Unity.Tiny.Rendering.Native\RendererBGFX.cs at around line 1334
