# Transient Attachments
|
|
|
|
The `transient-attachments` feature allows creation of attachments that allow
|
|
render pass operations to stay in tile memory, avoiding VRAM traffic and
|
|
potentially avoiding VRAM allocation for the textures.
|
|
|
|
Example Usage:
|
|
```
|
|
wgpu::TextureDescriptor desc;
|
|
desc.format = wgpu::TextureFormat::RGBA8Unorm;
|
|
desc.size = {1, 1, 1};
|
|
desc.usage = wgpu::TextureUsage::RenderAttachment | wgpu::TextureUsage::TransientAttachment;
|
|
|
|
auto transientTexture = device.CreateTexture(&desc);
|
|
|
|
// Can now create views from the texture to serve as transient attachments, e.g.
|
|
// as color attachments in a render pipeline.
|
|
```
|
|
|
|
Notes:
|
|
- Only supported usage is wgpu::TextureUsage::RenderAttachment |
|
|
wgpu::TextureUsage::TransientAttachment
|
|
- It is not possible to load from or store to TextureViews that are used as
|
|
transient attachments
