@ -14,7 +14,8 @@ following changes to the default bind group numbering have been made in 3d:
- `@group(3)` material binding resources
Most users who are not using mid-level render APIs will simply need to switch their material bind groups
from `@group(2)` to `@group(3)`.
from `@group(2)` to `@group(#{MATERIAL_BIND_GROUP})`. The `MATERIAL_BIND_GROUP` shader def has been added
to ensure backwards compatibility in the event the bind group numbering changes again in the future.
Exported float constants from shaders without an explicit type declaration like `const FOO = 1.0;` are no
longer supported and must be explicitly typed like `const FOO: f32 = 1.0;`.
