From 3b32c52e14a1732b37e56b7296725cd26adf2868 Mon Sep 17 00:00:00 2001 From: Gary Hsu Date: Tue, 24 Mar 2026 22:05:50 -0700 Subject: [PATCH 01/19] Add external texture array render test and fix numLayers bug - Add Tests.ExternalTexture.Render.cpp: end-to-end test that renders a texture array through a ShaderMaterial to an external render target, verifying each slice (red, green, blue) via pixel readback. - Add tests.externalTexture.render.ts: JS test with sampler2DArray shader. - Add RenderDoc.h/cpp to UnitTests for optional GPU capture support. - Add Utils helpers: CreateTestTextureArrayWithData, CreateRenderTargetTexture, ReadBackRenderTarget, DestroyRenderTargetTexture (D3D11, Metal, stubs for D3D12/OpenGL). - Fix ExternalTexture_Shared.h: pass m_impl->NumLayers() instead of hardcoded 1 in Attach(), preserving texture array metadata.
