True Sky

True-VFX in Materials and Shading

Why a minimum of Blender 5.1?
Blender 5.1 changed its underlying python version which required all including python modules TrueSKY needs to work to be re-built and therefore not backwards compatible. You do have access to previous files that did work in Blender 4.5, though some minor optimizations are not included in them.
Sky Appears Pure White

TrueSKY uses real world values which often times results in overblown images by default. Like your eyes and cameras the exposure of your scene likely just needs to be adjusted. If your sky appears completely white in the viewport or during rendering, check the following:

In Viewport:

Check Exposure settings:

Open TrueSKY Panel → Misc → Effects → Exposure and enable it.

Lower Exposure (e.g., around `-4.0` is common) and set Opacity to `1.0`.

In Camera:

When the compositor is set to apply only to camera views, the world background may look correct in camera view but blow out in the viewport.

In the Compositor, change Compositing Mode from Camera to Always.

HDRI Looks Too Dark or Washed Out

If your exported HDRI does not light other scenes as expected:

  • Ensure you exported the HDRI as OpenEXR with sufficient bit depth.
  • Verify that the source scene’s Color Management (view transform, exposure) matches your intended workflow.
  • In the target scene, confirm that the environment texture is interpreted as linear HDR data and not accidentally color-managed twice.
Performance or Viewport Feels Slow

Heavy clouds and volumetrics can be demanding on some systems.

  • Open the Performance lower tab and choose a lower-cost volume/quality preset while blocking out your scene.
  • Reduce cloud coverage and density in the Clouds tab to speed up both viewport and rendering.
  • Increase quality only when preparing final shots or test renders.
What render engine can I use?
This is a Cycles only product. Eevee is not supported
Why is my HDRI Render Button Disabled?

If the Render HDRI button is disabled or missing, the HDRI panel usually displays a hint explaining what’s wrong.

  • Make sure the HDRI camera exists by clicking Setup HDRi Camera in the HDRI tab.
  • Verify that an output directory and file name are set in the Output section.
  • Confirm that the current scene is saved so the add-on can derive a base path if needed.
No TrueSKY panel visible

If you cannot find the TrueSKY panel in the 3D Viewport:

  • Confirm the add-on is enabled in Edit → Preferences → Add-ons.
  • In the 3D Viewport, press N to open the sidebar and switch to the True-VFX category.
  • Make sure you are in a 3D Viewport area (the panel does not appear in the Image Editor, Shader Editor, etc.).
