Render Tools: is an set of tools very handy for Blender users can get ID Render pass and Mask Render Selected Objects. Similar what we have in Corona Render and Vray to have control in pos-production!
Blender Version Supported: Also work with the the upcoming Blender 4.0
Go to Edit > Preferences >1- Choose Install and select the render_tools.zip file
2- Activate it
3- In the side Panel you should have now a tab with the name Selection Tools where all the tools will be available.
ID Pass Tool:
With 2 clicks! you will be able to add randomly to the entire scene ID colors and render the final ID Pass image. You also have the possibility to add individually to each object a ID color.
Mask Pass Tool:
This is a very useful tool to quick select the object or objects that you want to render individually and press "Render Mask Pass", and you will get the final render only for the selected objects with transparency ready to compose in the final image. This too is similar what we find in Corona and Vray to quick render mask objects to fix things or update the final image without to have to render the entire image again!
Support: Also Motion Blur and Depth of field objects for the render Mask pass, for Still images as well for Sequence animation.
