This option allows you to save a 360 degree photo (Render), so if you have a particularly interesting 3D scene, you can save it as a background, and use it as any HDR in your library.
This step needs some attention, as it would be better to understand what it does and how it works exactly. The rendering will be carried out exclusively with the Cycles engine, as it is the only one at the moment
that can carry out this operation, and in any case it is clearly superior in terms of quality compared to Eevee render.
You can choose whether or not to use the denoise and which type of denoise, 3 options are available:
No Denoise will be applied to the render
Classic Cycle denoise
Compositor denoise node will automatically be applied to the render
CUSTOM SIZE: When active you can manually enter the size (integer), i.e. if you enter 4, the image will be saved in 4k (4096×2048), with the advantage that by any number you enter, the ratio will be set automatically keeping the proportion. This means that you can also enter other numbers not available in the existing 1/2/4/8 /16k list
1/2/4/8 /16K list: If “Custom size” is disabled, you can quickly choose between the preset formats.
GPU/CPU MENU: You can choose whether to render the background with the CPU or the GPU, if by any chance the GPU run “Out of memory” the add-on will automatically switch to CPU mode. Be careful not to overdo it with huge formats, as the memory used will increase exponentially!
SAMPLES: The more the number of samples, the more you will have a better image, but the rendering time will be higher, so pay attention, you can test the potential of your computer yourself. We recommend using the “denoise compositor” from the menu to reduce the noise, and to save rendering time.
ADD 360 CAM ON CURSOR: Place a sphere on the cursor, which in turn will be the position of the 360 camera, which in turn will take a photo (Rendering) you can see the 360 sphere in that photo:
Once you added a “Camera 360” the menu will have new functions:
PANORAMA SAVE: This button will start the rendering, nothing you will have to do, everything is already set up to create an HDR background, you just have to wait for the operation to finish.
360 CAM ON CURSOR: You will be able to move the sphere 360 on the cursor, (Available only if you have already added the sphere in the previous step)
FIND CAMERA: If for some reason you no longer find the “Camera” (Sphere 360), this button will move the view to the sphere
Make sure that the sphere does not touch any object, otherwise the portion of the object will probably be made invisible (Clipping), so keep a correct distance, as if you had a real 360 camera (A little bigger for safety reasons)
Now you can close the Rendering window
Now in the HDRi Maker panel, you will see a message and a button that was not there before. This was created for security reasons, since the preview is rendered in a separate scene. In this case the scene has remained in memory, so do not worry about anything and press “Delete batch scene” to return everything to normality.
Your 360 degree background from your 3D model is now saved in your library. You can use it as you wish.
The format of the saved background is HDR, if you want to export this background, you will need to add the background to the scene, and simply go under
the “Save menu” and press the “Export image” button, then choose the destination folder and the name, and press “Export”
