Live viewer COMMANDS
Live Viewer has some very useful commands and these commands provide you to work efficiently.
Now let's look at these in detail.
1- Send Scene and Start New Render:
This is the command you need to use when you send the scene to Octane for the first time. This command recollects the scene data each time and starts the render process from the beginning.
2- Restart New Render:
This command will only reset the number of samples and re-render without clearing the GPU data.
3- Pause Render:
This command allows you to pause the Render without clearing the GPU data. For example, if you have a heavy scene and you have to do some operations, it is recommended that you use this command. It works in Toggle mode.
4- Stop & Reset Render Data:
It is used to completely reset the data on the GPU. For example, let's say your job in LV is over and it's time to get a final render. It might be a good idea to use this command and reset all the data in the GPU before starting the final render.
5- Settings: See this section.
6- Lock Resolution:
The render resolution in LV is locked according to your project resolution setting. In some cases it is quite useful. For example, you can use this feature when framing the camera at your scene. Or to see your scene at the actual output resolution. When you activate this command, the numeric field next to Kernel Switcher also becomes active. Here you can increase your resolution.
7- Clay Modes:
It's just to make your render looks like Clay. Textures in Clay mode are not shown. You can use it to see how the overall light distribution in your scene. You can also use it for the overview of Shadow and Ambient Occlusion. It works in Toggle mode.
It is used to render the portion of the scene in LV. For example, if you want to make multiple adjustments to an object or material in your scene, you can select this command from LV and see only that part of render. It is a very useful option. You can then use this Region data in the Final render (this will be explained in detail in the Rendering section).
In Film Region, only the area you select is rendered in LV. Other areas are black.
9- Pick Focus:
With this command you can select any region or object in LV as the Focus Center (also select with CTRL + MMB button). It works with the Thinlens section of the Camera Tag, and the "AutoFocus" setting in the thinlens section needs to be turned off (will be explained in detail in the Octane Camera Tag section).
10- Pick Material:
You can choose any material in your scene through this option. Just click the material you want to pick in the LV. Sometimes It can be difficult to find what you are looking for in the Material editor. Use this option in such cases. It is a very useful command for many situations.
11- Kernel Switcher:
Here you can see how the scene in LV looks in other kernel mode options. For example, you can get a brief overview of how the scene looks at Pathtracing or Z-Depth. You can see some kernel modes in the image below. We'll also look at these Kernels in the Infochannel Section of the LV Settings.
