post_filter_selection not working on generic nodes

[david.sanda]

I use this code in plugin to add glow to selected nodes in the world.

        auto obj = Unigine::checked_ptr_cast<Unigine::Object>(node);
        for (int i = 0; i < obj->getNumSurfaces(); i++)        {            

            obj->setMaterialState("auxiliary", 1, i);
            obj->setMaterialParameterFloat4("auxiliary_color", color, i);
        }

with the generic initialization being

        Unigine::Console::run("render_auxiliary 1");
        Unigine::Render::setPostMaterials("post_filter_selection");

This works in the initial world loaded, as editor is started, but it does not work after another world is loaded like this...

    auto resu=World::loadWorld(world_name);
 

    auto pl = PlayerSpectator::create();
    pl->setPosition(Math::Vec3(0.0f, 3.401f, 1.5f));
    
        
    
    Game::setPlayer(pl);
    pl->setMainPlayer(1);
    Game::setEnabled(1);

 

 

 I know this is demonstrated in post_selection demo, but the loadWorld somehow breaks it.

Hi David,

Could you please send us a minimal test scene (data and source folders will be enough) and some step-by-step guide how to reproduce this behavior? Right now it's not completely clear the whole pipeline that you are using in your projects.

Thanks!

Anyway, if instead of

World::loadWorld("xy");

I use

Console::run("world_load xy");

the post_selection works as in your examples. Not sure what difference is there between these two methods of world loading, but as the problem is solved, you can close it.

Hi David,

That's interesting because internal implementation of these world loading methods are the identical. If you will have some additional time and could prepare a small test scene - we would glad to see what is going on and fix.
