 4. Select the object in `Menu` and adjust its pose, mesh and material in `Object Options`.
 5. Open the render window by clicking `Open Render Window`, setup the render image.
 6. Click `Start Render` to render your image. 
-    - It may take some time to render your image, as the duration of the rendering process is highly dependent on the complexity of your scene (number of primitives), the image resolution, the number of samples per pixel, and the max ray depth. For example, rendering a `640x360` image of `cbox.dae` with 4 samples per pixel and 8 max ray depth takes 1.2s on an i7-8750H laptop, while rendering `cow.dae` with a single directional light under the same image setting takes approximately 57s.

     - When debugging, we recommend rendering a coarse image with a low number of samples per pixel and a low image resolution, which could save a considerable amount of waiting time.
 7. Once you have created your own scene, you can export it by clicking `Export Scene` in `Layout` mode.
