Blender 4.5 LTS: EEVEE & Viewport¶
EEVEE¶
Shadow Terminator¶
A shadow terminator bias was introduced. This allows to remove the self shadowing artifacts on low-polygon geometry. (81c00bf272)
| Without Bias | With Bias |
|---|---|
 |
 |
Fixes¶
Fix shadow acnee issues using quantized geometric normal. This can slightly modify the shadow in some files. (410282e156)
Light leaking caused by large source light have been improved. This can make some surfaces darker than they were in previous version. (b01cdf7df2)
Navigation & Selection¶
Objects that are not marked selectable no longer affect selection and auto-depth. This improves working with semi transparent surfaces. (3dfec1ff73)
GPU based subdivision¶
GPU based subdivision is available using on Metal (32999913ef) and Vulkan (c7f7c03f4c).
Some performance figures: Suzanne 6 subdivision levels
| Machine | CPU Subdivision | GPU Subdivision |
|---|---|---|
| M1 Studio Ultra | 7fps | 12 fps |
| M2 Air | 3fps | 11 fps |
Vulkan¶
Vulkan is not experimental anymore. Vulkan support is on par with OpenGL.
- Missing features (OpenXR, Subdivision and USD/Hydra) have been implemented
- Performance has been improved.
By default OpenGL is still used. Users are encouraged to try out the Vulkan backend. Enable it in preferences.
Profiling¶
There's a new --profile-gpu command line argument that exports GPU and CPU profiling data (Docs).
