Ah, its working all good. Seems I just forgot my password (12 characters minimum) and a new one did the trick.

So its working! :D

General CG Discussion / Possible to run Corona 6 still?

I am getting somehow much lower parsing times than normally, thats one thing (not sure if this would be the cause with more than one frame preview tough).

This may be caused by different embree settings for IR and production rendering. But usually you get more rays/s when using the production acceleration structure. There are scenes (only few instances, large meshes) which are awfully slow using IR compared to production, so it depends on the scene.

Another would be a really fast animation preview using "fast preview denoise" - is there a way to turn this on when rendering frame sequences? If not this is the reason why. I am getting decent image preview after 10 - 20 seconds, ideal for rough animation.

The "Fast preview denoise" is the same as choosing "NVIDIA GPU AI" in Render Setup -> Scene -> Denoising -> Denoising Mode. So yes, you can use it for a frame sequence.

How a screen recording would do me good here? I cant set it for multiple frames with Corona render?

Yes, you cannot. That's why I wrote "in case of free navigation" (sometimes I use IR + screen recorder + 3D mouse to record the state of a model).

So it seems what remains is that you would like to use IR because of lower parsing times. Would be helpful to see a comparison from one of your scenes regarding parsing + rendering (the "Stats" tab from Corona VFB) for example an HD image with 10 passes respectively with comparable noise/noise level (10 passes IR do not equal 10 passes production regarding quality). I don't expect any large difference if you set production render settings low enough (this is what's happening when starting IR internally as well for a few values).


Good Luck

Alrighty, thank you for your time and info, the Nvidia denoiser was what I was after, after all.

Cheers!

What would be different to production rendering and lower settings? Or screen recording in case of free navigation?

EDIT - also saving time on "denoising each frame", because the fast preview denoise does that automatically.

Would be great to have a script that could save an animation sequence out of Interactive Corona Frame Buffer Preview.

Off-Topic / Offline web page builder
« on: 2021-10-07, 13:42:44 »
Hello,

I thought its worth a shot posting this here.

I remember back in the day I used to dabble in Flash and Dreamweaver, currenly Im a bit out of the loop.
Im looking for an offline web page builder, preferably WYSIWYG with visual programming, and preferably with a non-subscription model (although I can imagine thats hard to find).

Alternatively subscription base, but I would like to get my own seperate hosting for my webpage.

Would be oblidged if someone could point me in the right direction.

Cheers.

Would be great if this could be implemented, is there a reason why its not possible to save 16 bit .Tiff out of CXR?

Thanks.

[Max] Feature Requests / Re: Turn mesh into corona light
« on: 2021-10-02, 09:09:32 »
Most welcome! It is always good to ask :)

One useful thing I tought about having mesh to corona light converter, would be hiding all lights using shortcut command ;) (without actually using layers for this), for scene organisation.

But surely that would be overkill to the amount of programming needed to introduce this, especially since this isnt really a life saving feature.

If so thats actually interesting, not sure why I have read to stay away from corona light material, and rather use corona lights for gi.

You may have read some very old article or tutorial, IIRC back in the old days there was significant difference in speed, between Corona light and mesh light, but that has been resolved long time ago.

Ah, I think that might have been it. I had to have missed info on this, thank for filling me in.

Right, about what you ask - disks, cylinders, will render the same with a LightMtl as an actual Light (only the sphere is different).

As a note, perhaps you saw something about not using Self Illumination in a CoronaMtl, as that should not be used as a main light source as it is not processed as efficiently.

Also as a note, if you do something like a light bulb filament with lots of faces and fairly complex geometry, naturally this will take longer to sample - just as it would if we happened to have a "Filament" object as a choice in the Corona Light :) Here it is best to use a LightMtl with Emit Light off to give the visible glowing filament, and then say a regular sphere CoronaLight (set to be not visible directly) as the thing that casts light from the light bulb. Perhaps some information like that also lead to confusion?

Yep, Im aware of the trick to seperate self illuminated sources from actual light emitting sources. I think it was some old info that stuck in the back of my mind some time ago, but since the two are the same now, this renders this thread invalid.

Thank you for the input once again, and for clearing this out.

I know this might not be physically accurate, but sometimes this is needed for certain situations

In what specific certain situations you would find such a feature useful?

Studio lighting setup for product design. Actually I had to make a few workarounds to achieve my goal just yesterday, which is why this came to mind.

Actually any geometry with a Corona Light Material will render as efficiently as if it were a "Corona Light" (with the exception of a sphere, where the spherical Corona Light will in fact render faster and cleaner). Other than that, the Corona Light Material is identical to something being a Corona Light, so any "noise or problems" would be the same if it were a Light as there is no difference in how those are processed/handled.

Thank you Tom for your reply.

So, if I make a corona disk light (or cylinder), and make a disk/cylinder mesh, and add a corona light material to the latter - both will render:

1) Within the exact time frame achieveing very similar results
2) Will give as much illumination
3) Will be denoised within the same time frame using denoiser
4) Will produce exact amount of noise in very similar situations
5) Will give similar amount of gi to brighten up spaces

If so thats actually interesting, not sure why I have read to stay away from corona light material, and rather use corona lights for gi.

Hello, would be great to have an Override material that could be added to any object in the scene and have it affect (include/exclude) other selected objects based on:

1) Reflection/refraction
2) Cast/recieve shadow

So basically this is object properties settings but its per object basis for Corona Render.

For example: I have 2 spheres in the scene and a box - both have the same material but one has this override material : which makes the box reflection not visible just for this sphere (it is visible for the other sphere).
I know this might not be physically accurate, but sometimes this is needed for certain situations (also will remove post processing to achieve this effect).

Unless I am missing something and this is possible at this moment?

Thanks for input, cheers.

[Max] Feature Requests / Turn mesh into corona light
« on: 2021-10-01, 12:36:00 »
Not sure if I am missing anything, but why on earth is this feature not in Corona yet?

Back when I was working on Vray, they had an option to turn any mesh into actualy Vray light (convert the mesh) instead of using light material.

Please add this to corona, being able to convert mesh to actual Corona light, without the need of using corona lightmaterial (that causes noise and other problems, and should not be used to illuminate big spaces).

Thank you.

I think I just found one of the culprits of this...

Highlighting any of the 3d object in the scene, in the viewport resets the interactive rendering... I mean highlighting, as in hoovering (resulting with yellow highlights around the object)your mouse over the object and not clicking/selecting it.
So basically if I travel anywhere on my monitor with my mouse the interactive render triggers again - I have to keep my mouse inside the interactive rendering window for it not to reset, making me unable to multitask anything else.

Is there any way to turn this off?

Could be a million reasons. Forest pack, slate material editor, just a couple potential offenders that comes to my mind first.

Dont use either forest pack or slate material, Im on standard stack material mode (even tough its easy to switch between).

Im really using mostly default common tools (Corona Scatter for vegetation scattering).

Shame there is no override funcion/button. where the interactive render preview can be overriden, to only refresh using a button and not either:
manual camera movement, or just random decisions, not triggered by the users.
