This PR is based on top of #12982 # Objective - Mesh2d currently only has an alpha blended phase. Most sprites don't need transparency though. - For some 2d games it can be useful to have a 2d depth buffer ## Solution - Add an opaque phase to render Mesh2d that don't need transparency - This phase currently uses the `SortedRenderPhase` to make it easier to implement based on the already existing transparent phase. A follow up PR will switch this to `BinnedRenderPhase`. - Add a 2d depth buffer - Use that depth buffer in the transparent phase to make sure that sprites and transparent mesh2d are displayed correctly ## Testing I added the mesh2d_transforms example that layers many opaque and transparent mesh2d to make sure they all get displayed correctly. I also confirmed it works with sprites by modifying that example locally. --- ## Changelog - Added `AlphaMode2d` - Added `Opaque2d` render phase - Camera2d now have a `ViewDepthTexture` component ## Migration Guide - `ColorMaterial` now contains `AlphaMode2d`. To keep previous behaviour, use `AlphaMode::BLEND`. If you know your sprite is opaque, use `AlphaMode::OPAQUE` ## Follow up PRs - See tracking issue: #13265 --------- Co-authored-by: Alice Cecile <alice.i.cecile@gmail.com> Co-authored-by: Christopher Biscardi <chris@christopherbiscardi.com> |
