Comments on: RenderLayers – Selective Rendering

although your question is more than a year old …
you can save the renderlist once you've rendered all your planes and assign it back to your viewport after you've rendered your scene with the selective methode.

this.m_viewport.lastRenderList = this.m_savedLastRenderList.concat();

@Augie – I’d recommend adding MouseEvent handlers to the ViewportLayers. So once you roll over the viewport layer, you could start interacting with it and/or render it.

@Vico: I have the same exact problem, it seems that you can only interact with objects in the last ViewportLayer that you render. Does anyone know why this is? Vico’s workaround does not work for me, as I am stopping rendering on purpose, in order to tween the camera and a new 3d Object only (in order to achieve an “impossible” perspective). I think I might just have to make 2 papervision scenes on top of each other…

Hello john,
Thank you for all your tutorials, and congratulations on your new job.

I have made selective renderer, on one of my projects.
I have many planes, and I want to make a render only on the selected plane.
So I have my listeners on all planes (OBJECT_PRESS. ..). When I click on a plane, I select the viewportlayer and render only that layer. It works very well …
Except that I lose the interactivity on all my other planes …
I found a “temporary” solution, I make a render of all my planes once the animation of the selected plane over.
Interactivity on each plane returns.
But it made me a more render…

I do not understand why listeners disappear when plane does not render …

Do you have an idea where this might come?
maybe I did the wrong way ?

Hey John, glad to see you blogging again!

So even though you’re extending BasicView, this line –
renderer.renderLayers(scene, camera, viewport, rightLayers);

is necessary to get to the specified layer? Can’t you do-

startRendering(rightLayers); ?

Thanks again John. What if I were to want to index sort two viewports, render the back viewport once b/c it doesn’t change but not the front viewport? Is that possible with viewport layers or would they have to be two separate viewports rendered differently?
