Thanks, handy little script. How do I just get to know Corona's current gamma setting? Is it always 2,2 in newer builds even if I load a scene where an earlier Corona build was set to 1,8?

that's "iterative", not "interactive" ;)

My bad. opps. The twirly smiley :) face top right of the IR/vfb window keeps going when the render has reached it's limit in IR :) And the system beep doesn't happen (EDIT: Might be a good idea to keep the beep off cause that could get annoying).

Some feedback on IR in db from 11-Feb-2015:

- generally slower than it used to be some weeks ago (didn't test IR so much lately so not sure when it became slower)
- parameter changes (environment U offset for example) result in UI flashing and current UI element losing focus (cursor not in U offset field anymore, for example)

Generally, we absolutely NEED an indication when IR launches and does its scene prep, it needs to print 'IR working...' somewhere so the user knows that max isn't about to freeze.
Also, we need an IR launch button. I know the stance is not to have too many buttons but the dropdown IR launch is neither intuitive, nor do I get any feedback if it's been pressed or not (besides that there's no indication on the main Render button for a dropdown option). Please rethink this.

Old file opened in new builds: framebuffer gamma sets always 2.2.
but if you change framebuffer gamma in my script and save max file, then framebuffer gamma will be your value until you don't change it.

Thanks a lot, exactly the info I needed.

Oh man, todays build (13.02) is very laggy with IR, i went back to 11.02. Anyone else experiencing this?

already building fixed version

Hi pokoy
also you can use the panel from there - https://forum.corona-renderer.com/index.php/topic,6827.0.html

all values update when mouse moving over panel and when panel opens

I have created an entire exterior project based on Interactive workflow :) Will post it on Monday I think :D

Just noticed in changelog:

improved sampling of dim reflections on diffuse/refractive surfaces

Any example or metric to see ? Sounds interesting.

[racoonart]

There were reports about bad reflection quality with materials having high glossiness

I made some renders before and after. I also noticed that reflections are nearly perfect right away when the diffuse level is zero.
See the renderings below, these are all reflection passes, 5 passes default settings:
Left) How it was before the fix (Diffuse color is light gray)
Middle) How it is now (Diffuse color is light gray)
Right) How it is without diffuse (level is 0)

I'm still not sure why there is noise at all. The glossiness amount is very high, so for example the middle of the white reflections (CoronaLights) should be hit every single time (like in the right picture).

[Ondra]

the noise is there because the glossiness amount is very high, BUT the reflection albedo is low, so there is no guarantee that the reflection lobe will be sampled in every pass

Email sent. I hope I can hop in, drooling about ggx :D

Aargh, I've written an lengthy report and then our internet crashed.

So, the latest build is somewhat instable for me (max 2014, db 2015-02-15).

Issue 1
After rendering a couple of images, I am getting random scene prep hangs:
- on 'Parsing scene', max seems to iterate through an UVW modifier (modifier stack displays an UVW modifier that's instanced across 250 objects, UI flashes)
- CPU usage at one core, max' memory grows by 4 kb in 2 secons, max doesn't response and has to be closed forcibly

Issue 2
CoronaMultiMap renders a different random pattern than in earlier builds. Not sure if it differs from max session to max session or whatever else is causing it. I'd love to see it locked AND to have a random seed spinner like requested here: https://forum.corona-renderer.com/index.php/topic,7026.0.html. The current behavior makes it almost unusable in production unfortunately, it needs to produce stable and controllable results. It is super useful, it's just missing the last step.

Other than that, great improvements and fixes in the last days! IR is faster - great! - UI is still flashing on scene parsing however, but general changes don't seems to cause UI flashes anymore.
