Hey, everyone! Today we're releasing v1.6.0, featuring the below fixed issues and improvements.

Breaking Changes:

  • Re-designed the material definition system for flexibility and modding.
  • Removed support for the VK_NV_ray_tracing Vulkan extension, which is superseded by * VK_KHR_ray_tracing_pipeline and VK_KHR_ray_query that were added earlier.

New Features:

  • Added a setting to enable nearest filtering on world textures, pt_nearest.
  • Added a setting to enable the use of texture and model overrides in the GL renderer, gl_use_hd_assets (
  • Added support for converting sky surfaces into lights based on their flags, see pt_bsp_sky_lights.
  • Added support for IQM models and skeletal animation for the RTX renderer.
  • Added support for making any models translucent, and cl_gunalpha specifically.
  • Added support for masked materials (
  • Added support for polygonal light extraction from MD2/MD3/IQM models.
  • Added support for smooth normals on the world mesh through a BSPX extension.
  • Added support for unlit fog volumes. See the comment in fog.c for more information.
  • Enabled game builds for ARM64 processors.
  • Extended the "shader balls" feature to support arbitrary test models with animation.

Fixed Issues:

  • Fixed a crash that happened when loading a map with non-emissive lava material.
  • Fixed loading of multi-skin MD3 models.
  • Fixed long texture animation sequences.
  • Fixed some bugs in the model validation code (
  • Fixed some self-shadowing artifacts by increasing the shadow and bounce ray offsets.
  • Fixed some unlit or partially lit triangles by improving the BSP cluster detection logic.
  • Fixed the MZ_IONRIPPER sound (
  • Fixed the rcon_password variable flags to prevent the password from being stored (
  • Fixed the background blur behavior when the menu is opened on a system with over 24 days of uptime.
  • Fixed the barriers in non-uniform control flow in the tone mapping shader (
  • Fixed the buffer flags on the acceleration structure scratch buffer (
  • Fixed the crash that sometimes happened when entering The Reactor map (
  • Fixed the disappearing light surfaces on some polygons with almost-collinear edges.
  • Fixed the lighting on the first person weapon when it's left-handed.
  • Fixed the missing frame 0 in repeated entity texture animations.
  • Fixed the pipeline layout mismatch in asvgf.c (
  • Fixed the rendering of the planet's atmosphere in the space environment.
  • Fixed the sampled lighting estimator math, improved specular MIS.

Misc Improvements:

  • Allowed changing the VSync setting without reloading the renderer.
  • Extended the supported light style range to 200% to fix over-bright lighting.
  • Implemented anisotropic texture sampling for objects seen in reflections and refractions using ray cones.
  • Improved CPU performance by not re-allocating the TLAS on every frame.
  • Improved the handling of transparent effects in the acceleration structures.
  • Removed the fake ambient that was added when global illumination is set to "off".
  • Removed the initialization of the async compute queue, which was unused. This improves rendering performance and fixes some compatibility issues with AMD drivers.
  • Removed the MAX_SWAPCHAIN_IMAGES limit for XWayland (
  • Replaced the implementation of model data handling on the GPU to improve scalability (
  • Replaced the material BRDF with a more physically correct one and removed the non-linear albedo correction function.
  • Replaced the normal map normalization on load with a compute shader to speed up engine startup and map loading.
