The i915 kernel module allows for configuration via module options. See the "AccelMethod" option under intel(4) § CONFIGURATION DETAILS. pixelated graphics, corrupt text, etc.), try using UXA instead, which can be done by adding the following line to your configuration file: If you experience issues with default SNA (e.g. You may need to indicate Option "AccelMethod" when creating a configuration file, the classical options are UXA, SNA (default) and BLT. Note: You might need to add more device sections than the one listed above. Enabling GuC/HuC firmware loading can cause issues on some systems disable it if you experience freezing (for example, after resuming from hibernation). CBR rate control on SKL low-power encoding mode) may require the use of an updated GPU firmware, which is loaded by default only on Gen 11+ hardware since Linux 5.4. On supported Skylake and newer processors, some video features (e.g.

Kernel mode setting (KMS) is supported by Intel chipsets that use the i915 DRM driver and is mandatory and enabled by default.

This light and colour information is averaged and returned to the camera. The rays then return along their original path and transfer the information to a hemisphere above the GI point. They then hit other objects in the scene and record the light and colour information at that point. When a GI ray hits a surface, rays are bounced in all directions from that point. Subdivisions: 50 – 60 exterior, 80 – 100 interior Min Rate: The lowest resolution of the Irradiance map.Īim for 3 passes, so if you choose -2, choose -5 for min. Set to -2 and raise to -1 if you need better definition in the shadows. We are looking for a resolution equivalent to about 1500 – 2000 pixels.

Zero is full resolution, so 4000 pixels in this case. Max Rate: The maximum resolution of the irradiance map. Just remember that the Irradiance map subdivisions will also multiply. In simple scenes you can really ramp this number up, assuming your materials and lights have a low subdivision figure (8-16 or so). That is where the maximum image sample limit kicks in and stops it from endlessly sampling.Ī quick way to raise the lowest quality areas.Īn easy way to increase the quality of lights and glossy reflections in your scene. This is why Vray has a tough time with very high changes in brightness because it will never achieve this tolerance. 002 is telling Vray to keep shooting more samples and sub divide pixels until adjacent pixels are within this range. This is the maximum allowed difference in pixel value on a floating point scale. Lower values will increase the quality by not allowing Vray to lower the subdivisions for materials and lights deemed low importance, (distant lights and objects, darker objects)
