**System Information** Operating system: Windows 10 Graphics card: NVIDIA RTX 2070 Super **Blender Version** Broken: 2.91 Worked: (Nothing since collection system was present) **Short description of error** Objects with volume material is included in render even when it's inside HOLDOUT collection. Apart from the question whether volume material should mask the other collection, it should not be rendered like it normally would. **Exact steps for others to reproduce the error** It's very simple. 1. Make a new collection and enable holdout. 2. Make a new icosphere object inside the new collection. 3. Give the icoshpere a volume material(Simple principled volume is fine). 4. Move the icosphere in front of the camera, making the default cube go behind the icosphere inside the camera view. 5. Render the image. You'll see that the holdout is not working properly for volume material objects.
