Great tutorial, thanks! I am still new to Blender and that's probably why I run into 2 issues. When I parent the frustum to the camera the frustum moves under the camera in the outliner preventing me from adding it to a collection. I fixed this by duplicating the frustum and transform constrain it to the original frustum then using this copy in a collection as a brush. But then I don't get weight paint to show up. I wonder if this is a 2.93 LTE version issue or because I set the brush on a duplicate of the frustum. I rebuilt it about 5 times to no avail.

This is great. I already had a weight map controlling density/scale and I muddled a solution using attribute subtract on both weight maps with the second operand being inverted, with the result being placed in a third vertex group. This resulting group was used in the point distribute node. Also there is a great tutorial by Gleb Alexandrov on camera culling where the vertex group generated in the dynamic paint modifier can be used to hide geometry by simply adding a mask modifier with vertex group assigned. Unfortunately in this case the mask mod changes the distribution of instances but is useful for high poly models in a scene. Perhaps someone can put out a vid on this as I cannot. Thanks

To join masks the best way is either add or multiply. If you want where either is true use add, if you want where they're both true at the same time (like this case) then multiply. Just attribute math set to multiply on your culling and path attributes and it should work! You're right about the mix though that makes sense to do a whole tutorial on for sure!

If you use an Attribute Vector Math node set to distance and calculate the distance between the position attribute and the camera location (use an Object Info node set to relative). Then if you use an Attribute math node on the result attribute from the distance, set it to divide by a float and that float is your falloff distance, and then use an Attribute Colour ramp to give you the manual control you want on how it grows up/down around the camera.

I have a better solution to this, that is entirely GN and works without any hassle or trouble. First I made a node-group to generate camera-plane, which uses some simple math that I've since forgotten. Then I do a RayCast from every point on the mesh to the camera plane. If it hits the camera plane, good! If not, it's culled. Then I do a second raycast to the occlusion collection to see if something else is already in front of it - if so, it's culled! It's really simple and easy to use once it's all set up. BONUS: mine also can partially cull based on distance, so that e.g. grass can use the cull value to get smaller or less dense based on distance.
