From a281ffa32ea615670d369503692f057b2dc60e6f Mon Sep 17 00:00:00 2001 From: Valentin Popov Date: Thu, 19 Feb 2026 05:19:18 +0400 Subject: feat: Enhance model and texture loading with improved error handling and new features - Introduced `LoadedModel` and `LoadedTexture` structs for better encapsulation of model and texture data. - Added functions to load models and textures from archives, including support for resolving textures based on materials and wear entries. - Implemented error handling for missing textures, materials, and wear entries. - Updated the rendering pipeline to support texture loading and binding, including command-line arguments for texture customization. - Enhanced the `texm` crate with new decoding capabilities for various pixel formats, including indexed textures. - Added tests for texture decoding and loading to ensure reliability and correctness. - Updated documentation to reflect changes in the material and texture resolution process. --- docs/specs/texture.md | 14 ++++++++++++++ 1 file changed, 14 insertions(+) (limited to 'docs/specs/texture.md') diff --git a/docs/specs/texture.md b/docs/specs/texture.md index 5fa1e9d..c25ec56 100644 --- a/docs/specs/texture.md +++ b/docs/specs/texture.md @@ -59,6 +59,20 @@ pixelCount = sum(max(1, width>>i) * max(1, height>>i), i=0..mipCount-1); sizeCore = 32 + (format==0 ? 1024 : 0) + bytesPerPixel * pixelCount; ``` +## 4.1.
