NEED CAMERA EXCLUDE OBJECT， This function is too important for us, thank you!

[Anonymous]

Sometimes we want some cameras to automatically exclude some objects during batch rendering, which is too important for multi angle batch rendering of a scheme! We are eager to add this function to the software and hope to get an official reply! thank you!

So ... To begin with, there is no way for the Camera object to exclude certain nodes from rendering.
But ... you can define some nodes as not renderable.

What we can do? Using the #preRender callback, determine which camera the rendering is from, and put all the "excluded" nodes for this camera in the "not renderable" state. And of course, we can return all back after the render.

If such a solution is interesting, we can continue the play.

In batch rendering, we want some models to be invisible to a camera; But when rendering another camera, we want those models to be visible while another model is invisible. Isn't it better and more convenient to add an exclusion function to the camera in the software? Please note that I have been emphasizing batch rendering!

I don't understand software design, but I believe the software development team can do it by adding the function of excluding some models to the camera. Thank you!

This function is urgently needed by many designers. I hope the official can find a way to realize it in the software! thank you!

it's alredy there. you can use #prerender script to set any node states before rendering. also you can specify a scene state before rendering and a render preset (where you can specify how render or not hidden geometry for example)

here is how to specify prerender and postrender scripts. these settings are the part of render preset.

Thank you very much for your patience. Your method seems too troublesome for designers who don't understand scripts. We want to know that it is impossible to add the function of excluding certain objects to the camera in the software? It is similar to excluding objects by lights. If you can do this, users will be more convenient! Thanks again!

[Anonymous]

In addition, we want to know that since the light excludes objects, we can do it! Why not add the same function to the camera?? This is the wish of many designers!

The Scene States mechanism was added to the system primarily for the specification of the scene and rendering conditions in the Batch mode. 
Managing and editing scene states does not require special skills from the artist or designers. At least this is no more difficult than setup including/excluding node sets of lights.

If you can describe in more detail the conditions or the rules of your batch rendering, maybe I or someone else can suggest you a more convenient solution. What is common practice and regular task for a Technical Artist, which should usually be given to assist artists and designers.

[denisT.MaxDoctor]

Objects in a scene can have more complex rendering conditions rather than just a simple inclusion/exclusion. An example, visibility in reflection/refraction, receiving/casting shadows, effecting by atmospherics and occlusion ... All this would be difficult to control only from the camera side.

Thank you. Sorry, we are too busy recently and didn't reply in time; In a few days, we will sort out our usual workflow and batch rendering process in detail. You are very professional! We hope you can give us the most convenient and efficient solution! Thank you.

What is the purpose of your batch rendering? For rendering a few files from many cameras or for rendering many different files?

[Anonymous]

Of course, multiple cameras that can batch render multiple files are the best, but first we have to solve the problem of multiple cameras for one file, which is the most common problem in our work. It must be ensured that during batch rendering, the camera can automatically hide some models according to our needs, as if those models never existed.

[Anonymous]

In fact, what we really hope to do is that Max software itself can add the function of automatically hiding some models to the camera, just like those models never existed，THANK YOU!

[Anonymous]

We only need to batch render single frame files of multiple camera angles of a large scene to determine the final scheme for customers; That is, the rendering effect of a large scene with multiple camera angles. We don't do animation! Do you understand? thank you!

[Anonymous]

The most perfect state is that the camera can automatically exclude some models according to our needs, and automatically hide those models we don't need in the camera viewport, and supports batch rendering. THANK YOU!

[Anonymous]

We very much look forward to the fast and convenient solutions from the masters，THANK YOU!

Why don't you use already existing solutions instead?

Scene States, LPM, Prism, RenderStacks, Vexus, etc...

Which ones have you already used?
