Blender Day 54 : Blender54 How to use slot to render multiple image in blender

Hello, everyone! It's William Jiamin here, and in today's video, I want to share with you how to adjust the rendering output and the process of actually rendering your scene. So let's get started!

First, make sure you have set up your camera and chosen the GPU to assist with rendering. Once that's done, we can proceed with the actual rendering process. To adjust the output properties, simply click on the "Output Properties" tab. It's quite straightforward.

If you want to change the camera you're using, just click on the camera icon, and this will adjust the render engine accordingly. Additionally, if you plan to print your image, there is an option that resembles a printer icon. From there, you can choose the format. The resolution is usually set to match your screen's default resolution, such as 1920 by 1080, but you can adjust it as desired. If you want a 4K resolution, for example, just click and drag to increase the width. Alternatively, you can adjust the percentage value to scale the resolution.

For instance, even if your screen resolution is 1920 by 1080, you can increase the resolution by adjusting the percentage value. This is similar to how the resolution on a phone remains the same, but the pixels per square centimeter increase, resulting in a higher resolution. So instead of directly changing the resolution, just modify the percentage value. It's a more intuitive approach. You can choose 100% for the default resolution or increase it as needed.

Once you have everything set up correctly, it's time to start the rendering process. In this example, I'll demonstrate using both 100% and 200% resolutions. Remember, we are using the Cycles render engine. To initiate the rendering, you can either click on the "Render" button or press F12, as Blender is heavily shortcut-focused. The rendered image will then appear.

You can switch between different rendering slots to compare the results. By default, slot one has no lighting, so make sure to enable it for accurate comparisons. You can see the rendered image in slot two. To switch to slot three, simply close the image in slot two. In slot three, we'll increase the percentage to 200% and render the image again.

As you can see, the image in slot three is significantly bigger than the previous one in slot two. However, keep in mind that rendering may take some time, especially for complex projects. In such cases, rendering large-scale landscapes with lots of grass and trees can even take days. In those situations, you may need to use remote computers to speed up the process. It's a good idea to have a cup of coffee while waiting for the final result.

Remember, rendering is a time-consuming process, especially when dealing with animations. If you make a mistake, it can be quite frustrating to redo the entire rendering process. So double-check everything before rendering, especially if you're working on an animation.

You can compare the results of the different rendering slots and resolutions. Slot one represents the disabled lighting, while slot two and slot three showcase the rendering with different resolutions. The difference is quite noticeable, even when the image size remains the same.

Lastly, don't forget to compare the results between different rendering engines, such as Cycles and Eevee. Eevee is much faster, even with a resolution of 100%. So you can quickly switch between engines and press zero on the numpad to get a preview. If everything looks good, enable or disable the necessary elements to ensure you render exactly what you need.

Rendering can be time-consuming, so grab a snack and a cup of tea while you wait for the process to complete. I hope this tutorial helps you adjust the rendering output and successfully render your scenes. If you found this video helpful, don't forget to subscribe for more Blender tutorials.
