Rendering

Start small

Start with the default cube. Choose EEVEE, set the output to 512 by 512 pixels, and render one frame. Check that it finishes before opening a larger project.

Workbench solid shading and EEVEE use Metal. Big textures, dense meshes, and rendered viewport shading can use a lot of memory, so save before switching to a heavier scene or starting a render.

Cycles

Cycles includes CPU rendering. It’s a useful fallback if GPU rendering isn’t available or a scene gives you trouble. Choose Cycles in Render Properties, then select CPU. Start with a small image and a low sample count.

Cycles also includes Metal support for compatible devices. It needs GPU features that aren’t available everywhere, so the option may not appear. Try a short render before committing to a long one.

What’s missing

OSL shaders and Blender’s Hydra render integration aren’t available. A project that depends on either will need changes. See What doesn’t work before bringing over a more involved setup.

Long renders

A long render can heat up the device, and iOS can close the app if it uses too much memory. Save your project first. If a render won’t finish, try a smaller image, fewer samples, or lower-resolution textures.
