Mirrors and Visualizer

[lightmap]

Hello,

I'm followed mirror example https://developer.unigine.com/en/docs/2.7.3/code/usage/mirrors_viewports_materials/index?rlang=cpp&words=mirror
and find out that all helper geometry, rendered in main window with visualizer, are not showed in mirrors.

Is there some flag to enable visualizer for viewport.renderTexture2D() ? way around?

Dear @lightmap,

I have not run this particular example. But I think following line is doing it.

viewport->appendSkipFlags(Viewport::SKIP_POSTEFFECTS);

This is important when we use render functionality attached to view port. With every render call we might require to bypass few of the rendering passes from UNIGINE rendering sequence. Due to above optimization the post effects of visualizer drawing will not work as they are skipped.  

Again the one big mirror is reflected using planar reflection. There is a note too. 

Planar reflections don't reflect each other and miss post-effects.

And if planar reflection don't  miss post effects then we will render everything to 10-15 fps. Just a comparative example to make  sure that post effects so many times will eat up fps.

Are you checking this behavior in editor?

Rohit.

Thanks, but it not hepls.

Im checking not in editor, and not use planar reflection, only renderTexture2D, and SKIP_POSTEFFECTS did not help.

Rendered texture still has no visualizer primitives drawn, as in main window scene are.

SKIP_VISUALIZER flag is set by default when creating a new viepowrt

So you need to adjust your viewport constructor and explicitly pass required flags on creation.

Thanks!
