Scale to Region - Feature Request

[EDELVIZ_ARCH]

Hi Vladimir,

most of my work is on large print res images. And I can not preview details in RT without having to either move the camera closer in or take a full render of a region because it gets so small in the render window that you can not make out details.

I would love to have a button that would trigger a behaviour where the render region/red box drawn is scaled up to the full rt window (proportionally of cause) so that i can see the details in that region. I have attached a series of images to illustrate and hope the idea is clear. This would be super helpful in my work.

Thanks and all the best,
Jonathan

YES PLEASE!
I always add another camera just to test/see details in RT. This is such a good idea.

+1 !

But I don't know if it is purely dependent of Modo or if it needs an update of the V-Ray core ?

We have something similar with shift+scrollwheel in modo preview

+1 I like that idea better than the scroll wheel TBH as it would make it easier to pop back and forth between full and zoomed renders.

While the mouse wheel zoom is intuitive and nice in MODO, it gets clunky fast on complex scenes. This would solve that probably.

Going one step further- it would be nice if we could draw more than one region, and then when the region tool is active, select one and have that be the actively updating region + zoom.

Further yet, also letting us do similar with render masks.

While the mouse wheel zoom is intuitive and nice in MODO, it gets clunky fast on complex scenes.

But this feature boosts especially the speed of setting up a scene, tweaking shaders and troubleshoot areas by freely choosing the zoom-level, whereas when you draw a zoom region it only toggles bettween original view, and zoom-region. Of course you can draw another zoom region and update the view again, but I don't know if this would end up being a "clunky" solution as well. A combination of both would be ideal, but if I'd have to choose between those two, I'd choose the mouse-wheel solution, because for production-render crop of your existing scene you can still rely on 3rd party tools like CROPPER.

I don't find it clunky. I think having to draw a render region, then zoom on it is going to be way "clunkier"

I'm not disputing the need or the uses of a mouse wheel zoom though- I find that idea for setting up materials at first and such too. I just thought having both could solve a bunch of issues neither one address on their own. I do think it's imperative to mouse wheel zoom in Vray for MODO- it's one of previews many nice features that I miss when using RT.

I should have chosen my words better (as usual). I meant slower as in CPU time slower, clunky was a poor choice of words. Sometimes things get so bogged down I'm zooming in and out of just pixels. So I get kind of lost in a pixel sea. This isn't on most scenes though, but some heavy ones where things take a while to resolve in Preview feel this way for me.

In an ideal world we'd have both a mouse scroll wheel and the render region(s) with the ability to click and zoom.

What I was saying too was that if the region could be almost like an active zone, where in if you click on it or use a modifier key and click, it fills your vfb viewport with the region. Click again with same modifier key on the vfb viewport and it zooms back out. Then if you had different regions you could pop back and forth between them and the full view easily.

So say I have one region on a lamp, another on a ring on a table, and another on a chair. I often find myself bouncing around things like this- and as fun as mouse zooming is, it's tedious. Yes, I can setup several VFB windows and do this I guess, but then I'm taking up a lot of screen space just to have these regions.

Add to the fact that while RT is getting snappier all the time, it's still not as snappy as preview is, at least initially, so I'm not sure just having a mouse wheel zoom is the ideal solution for everything.

If you activate "immediate camera update" you'll get a much faster response which has the downside that it chooses always the camera-view you've selected for preview, so not only your definded camera, but also the perspective view, top view, side view. This happens due to a limitation of MODO's API (at least, that's what Vladimir said). It's not always a bad thing though, because this way you'd have an independant camera for preview purposes buuuuut: The rendering of the perspective view doesn't really represent the viewport. The rendered view is far more closer to the model than it's in the viewport. So far I haven't found a solution for that issue

I'm sure it can be done better than this, but it seems we should be able to create something half baked while we wait or use Adam's plugin.

I'll post the scene and or assembly when it's a bit further along.

That's too bad really. Need TF to either fix it or help Vladimir find a work around.

I've found some render settings (like using brute force for both primary and secondary), setting the under sampling higher, ray bundling etc. can help too. At least in terms of getting faster initial interaction.

So, this feature is in the nightly builds from today - 2017.04.03 .

Here is a few notes:
- the new functions are accessed by either right-clicking on the image in the VFB while RT is running or from the "En" button from the V-Ray toolbar
- you can Shift + mouse scroll wheel to enhance zoom the image, like in MODO Preview
- you can Shift + middle mouse button to pan the zoomed in image, similar to MODO Preview, in MODO Preview the Shift key must not be pressed
- you can draw a render region and then use the "Enhance render region" command to zoom in on it, like the initial request here
- you can save/load the enhance regions

Here is a short video that shows the features : https://youtu.be/1ASibuL7aaU

@Vladimir

I have been using this feature the past few hours and I don't know how I lived without it. It's really working a lot better than I expected!

I work with a small vfb in my custom layout and its great being able to zoom into details without having to expand viewports, open new windows, creating temp cameras etc etc

Really well done man. Fantastic addition! Thank you for spending time on it.
