Use the projector to output the image

[qwe123]

Scene: Multiple computers, each computer corresponds to a projector, and runs a unigine app, and sets different model view matrices for different programs.

When rotating the scene, the output of the projector swept by the sun will dim. I am using version 2.6.

 Waiting for your reply,thank you.

It’s difficult to understand without a screenshot or video what we’re talking about. but perhaps this is the result of autoexposure

try to disable it on all instances 

Render::get()->setExposureMode(0);

This picture describes my previous problems.We have unified the brightness of all projectors.

There are obvious light and dark changes between the outputs of different projectors.

[qwe123]

In these two outputs, I turned off automatic exposure, but there is still a clear gap.

What's the possible reason? Looking forward to your reply.

Hi. 

For a virtual Multi camera setup you can not use Screen post effects (or some but with limitations), e.g. Bloom, dynamic things aso.

I just came into contact with the 3D engine and don't know much about what you said. Do you mean that it doesn't work in principle?

hi. Sure it is working.

Some things are rendered in screenspace, some are not. The one e.g. camera effects or dynamic stuff might deliver different results per viewport, so you cannot use them when rendering to multiple screens.

You can try the virtual resolution and the borders

https://developer.unigine.com/en/docs/2.18/editor2/settings/render_settings/screen/?words=resolution%2Cvirtual%2Cresolutionlll%2Cresolut%2Cresolutionll#highlight

see if that is useful.

Pls see the documentation, which is quite informativ ;)

Best.
