Creating Direct Caustic Effects

You can create direct caustic effects for a more photorealistic rendering of your model.

1. Set up a spot or point light, point it at your model, and turn it on in PhotoView.
2. Add a floor by creating physical geometry beneath your model or adding a floor appearance to the scene.
   Direct caustics only appear when reflected off physical geometry or a floor appearance

3. Click PhotoView 360 > Options.
4. In the PropertyManager, select Direct Caustics and set the Caustic Amount and Caustic Quality values.
   Higher values for Caustic Amount increase the visible area and intensity of the caustics. Higher values for Caustic Quality increase the visual quality of the caustics.

   As you decrease the caustic amount, you may want to increase the caustic quality to avoid graininess. As you increase the caustic amount, you may want to decrease the caustic quality to create a sharper appearance. Higher values for Caustic Amount and Caustic Quality increase rendering time.

5. Click .
6. Click PhotoView 360 > Final Render.

   The Preview and Final Render windows open. Direct caustics are only visible in the Final Render.
