Display layers to NOT update in RT

[seandunderdale]

Ive asked this before, but I haven't found a workaround. I do a lot of automotive work with CAD poly sets so there's a lot going on in a headlight / tail light and often they're supplied in a way that needs a lot of fixing. My workflow was to frame a headlight, fire up RT, and add layer after layer of lenses, chrome and plastic to a temp hide display layer so I could dig down into the lights and make changes. This meant my lights rendered as a complete beauty, but I could rummage around in viewport and not have to be showing all the headlight lens layers at once, and have a simplistic view of only what I needed to see in the viewport.

Now display layers update with RT and its very hard to pull apart a complex model with RT running and viewing the result as a beauty render. Sifting through a CAD model inside a headlight with everything on, so my render stays as a full beauty is a nightmare. Is there any way this behaviour can be tweaked so its an option to NOT have display layers update?

Using Vray Next 1.1 and Maya 2019.

We can give it some thought, definitely, but I can't promise what the outcome will be. We've had reports in the past, where people specifically asked for display layer visibility to be updated in IPR.

Cheers Alex. I can see how it would be very useful to update and have display layers and IPR synced. The only problem for me is, the way it was is 3.6 was the only way to visually dissect a scene and still see the beauty render in IPR (That I know of). Isolate select doesnt quite work as I usually need to be progressively hiding parts of a group, rather than islotating one object. I totally get it that you might not want to change it, as it might not be a very popular way of working.

Hi Sean. Head lights are a pain to deconstruct. My random method is to explode them forward. And deconstruct then that way. Then move them all back once I think I got it.

Ive started making a display layer set to bounding box in the viewport. I assign stuff to that layer that I want to see through and get to stuff behind it. That way the beauty render stays correct and the viewport is easy to navigate still.

Yeah i submitted a bug because the display layers werent being updated in RT, which really should be the default, just because display layers are basic options in maya, but I can see how it is a problem too.

Having a toggle button in the vfb could be useful.

After all this time using maya, i never looked at the display layer set to bounding box options....crazy

I actually prefer how it is now. Lots of flexibility. Ive always got a "Temp_hide" display layer and a "bounding_box" layer, and Im adding, emptying, removing selected constantly. The temp hide actually hides geo in the render if needed, and the bounding box layer just hides in the viewport so I get into a headlight, for example. Allows a lot of drilling down into assets without disturbing the beauty result, and without restarting RT.
