Regression
Yes
URP Simple Lit shader does not bind lightmaps correctly
*Steps to reproduce:*
# Download [Adventure - Sample Game|https://github.cds.internal.unity3d.com/unity/Adventure-Sample-Game] project (pull LightBaker branch)
# Open Market-Nighttime scene
# Make sure that Double Sided Global Illumination is unchecked in the material properties
# Make sure that Auto Generate and Progressive Updates are unchecked
# Bake lighting using CPULM or GPULM
*Expected result:*
* Lightmaps are correctly applied to world geometry
*Actual result:*
* Lightmaps are lacking indirect bounce, and are incorrectly composited. Errors are thrown in the console (see [^Editor-Bug-ShaderBinding.log])
*Notes:*
* The following error is thrown in the console: {color:#27292a}Metal: Fragment shader missing texture binding at index 0 (unity_Lightmap / Universal Render Pipeline/Simple Lit){color}
* {color:#27292a}When baking with the GPULM, the following errors are thrown: {color}
[BakePipeline::BakeStage] Bake took 17030.24ms and failed with code 5.
#0 GetStacktrace(int)
#1 DebugStringToFile(DebugStringToFileData const&)
#2 (anonymous namespace)::RunBake(void*)
#3 Thread::RunThreadWrapper(void*)
#4 _pthread_start
#5 thread_start
* Clearing baked data, library folder, GI or shader cache does not fix the issue
* {color:#27292a}Observed in 582a02a42f59{color}
