Figure 6.35 - Render preview with Cycles

Those interactions in Cycles have a limit that you can adjust at the

Render tab.

Tip: You can interrupt the render for your preview using the pause

button next to the shading modes selector.

In the Sampling field, you find the limit for interactions for both the

Render and Previews. The default value for your 3D Viewport (Previews)

starts with a minimum of 0 and a maximum of 1024 (Figure 6.36).
