[Max] General Discussion / Re: Autobump concerns and 2d displacement ala vray

« on: 2018-11-30, 09:23:15 »

I'm assuming this auto-bump is the one you have to enable in the develop/debug mode?

If you don't enable it - has the normal default (tesselation method) been improved at all in Corona 3?

Only asking as the 'Highlights of the Release' state the following "- Displacement improvements allow you to use lower Displacement settings with the same image quality, lowering memory usage by up to 50%."

Is that statement a by-product of autobump, or just a general improvement to displacement?

From the use of the Autobump. Other than "sharper textures at grazing angles" which will improve the look of displacement (with more detail, at grazing angles :) ), there isn't any other changes that would affect the displacement system.

Just to clarify, IES is a form of directionality, so has the same effects (anything outside the cone of the IES will show as black, as that means no light rays are being sent out in that direction; the prevent black appearance fixes that in direct visibility, for IES as well as directionality, since it's the same underlying cause; but neither IES nor directionality will be fixed in reflections / refractions with the prevent black appearance)

Well, that is why the forum is an acceptable way to report bugs, and does feature that kind of search ability :) The ticketing system is not the only way to report.

[C4D] General Discussion / Re: Bloom and Glare on Selected object..?

« on: 2018-11-28, 15:19:05 »

Bloom and Glare is a 2D process (like in the real world, where it occurs due to the lens) and is based purely on pixel intensity, so at the moment (like the real world) there is no turning it on and off for specific objects etc. (so one thing to consider is the light intensity, and manipulating the Threshold parameter, to limit it to things of a particular brightness, which can be above 1 in the Threshold for things that exceed RGB 255,255,255 as far as I know)

Any chance of sharing the material set ups? A look at the renders doesn't look to me like a difference in the Diffuse channel, but in the Glossiness, Fresnel, or some other reflectivity attribute. Could simply be a case of the material not being converted properly, rather than any inherent loss of detail in a map.

EDIT - I am not sure what the third image shows, so can't comment on that :) Just looking at the "looks more rubbery" and the clear differences in reflectivity between the two renders.

[Max] Bug Reporting / Re: 3dsmax is not responding - corona 3

The GPU denoising should work well in most cases - it works even with my very old 680 GTX, but, it can be a bit slow there at times; e.g. as IR or final render resolution goes up, that can make things slower, and it can as a result cause my computer to have pauses and short lock-ups because it only has 2GB GPU memory, which is what makes me wonder if this is having an impact on the performance you are seeing, and whether disabling it improves things. Let us know when you get a chance to test!

Probably the best solution here is to have two objects, one for casting light into the scene (that doesn't appear in direct visibility and reflections), and one for appearing in direct visibility and reflections. The thing about IES or other form of directionality is that it can mean that light from the light source doesn't go where you think it will - the "Prevent black appearance" will generally resolve that for direct visibility, but it may not resolve it in reflections (for now, at least).

Without knowing more, not sure, but the CoronaDistance map could prove very useful for the case of having ripples (or other changes to the material) conform to a shoreline etc. Some simple example scenes at https://coronarenderer.freshdesk.com/support/solutions/articles/12000017221-what-is-corona-distance-map- (just in case you don't already have those and they provide a good starting point).

For those experiencing lags and long waits, did you try disabling the NVIDIA denoiser?

https://corona-renderer.com/blog/wp-content/uploads/2018/11/corona-renderer-3-denoise-during-render-ui-b.png

It would be good to know if that was on or off when you experiencing these problems, and whether disabling it improves things. (Note that if you are using denoising in a final render, would be interesting to know whether the NVIDIA denoiser was chosen there - I would try using the Full Quality there, with the IR denoising unchecked, and see if this changes responsiveness at all).

Thanks!

« on: 2018-11-26, 13:48:16 »

If you are having issues in IR, those can most likely be avoided without downgrading to Corona 2 by turning off the "Fast preview denoise during render" (see the image in the blog, at https://corona-renderer.com/blog/wp-content/uploads/2018/11/corona-renderer-3-denoise-during-render-ui-b.png). Just to confirm this is what you meant by "deactivating the denoiser" (rather than just turning it off as the final render in the dropdown list for that, which won't affect whether the NVIDIA denoiser runs in IR).

News / A farewell to MANTIS bug reporting

« on: 2018-11-25, 16:56:24 »

Hello all!

We want to inform you about changes to the bug reporting process here at Render Legion.

Way back in the mists of time when Corona Renderer was first launched, we opted to use Mantis as the method for you to report bugs to us, and for us to use to track progress on resolving those issues. It has served us well, but it was complex for you, our users, to have to use a full bug tracking system just to REPORT the bugs to us (as many features in Mantis existed to help us track things).

Recently, we have moved to a more streamlined internal tracking system, which improves our ability and speed in tracking, managing and fixing bugs. As a result, it also means that you don't have to use something complicated like Mantis to report to us, and it means you will have better communication and response times on the forum and on the helpdesk.

Here's what you need to know:

- Unresolved tickets on Mantis will still be worked on and resolved (in other words - Do Not Panic!)

- No new tickets will be created on Mantis

- To report bugs to us, please use:
  - The helpdesk ticketing system at https://coronarenderer.freshdesk.com/support/tickets/new OR
  - The forum board related to the version of Corona that you use:
      3ds Max / Corona Core : https://forum.corona-renderer.com/index.php?board=2
      Cinema 4D: https://forum.corona-renderer.com/index.php?board=36
      ARCHICAD: https://forum.corona-renderer.com/index.php?board=47

- Once again, that's an "OR" - use the helpdesk ticketing system, OR report on the forums, not both please (which will actually only slow things down, both in terms of us being able to fix the issue, and in being able to respond to you promptly)

For more information on bug reporting, including how to make your report as useful as possible for us so that we can resolve it faster, please see:

[Max] General Discussion / Re: CORONA 3 NVIDIA AI Denoiser

« on: 2018-11-25, 16:49:36 »

Isn't it supposed to be on by default like it says on release notes?
Mine is not

Are you sure? Remember, there are two locations for this to be enabled, one is the final render (the drop down list for Denoising, which used to be the only place to set Denoising, and is not on by default); the other is Denoise during render which should be on by default (assuming you have a GPU that supports it of course), and that's in the Performance tab in the render settings (see image in the blog, https://corona-renderer.com/blog/wp-content/uploads/2018/11/corona-renderer-3-denoise-during-render-ui-b.png)

Let us know :)

[C4D] General Discussion / Re: Your experience with teamrender

« on: 2018-11-23, 14:34:11 »

Ok, after rendering a new Project with 20s update interval and 200MB Packet size, it renders way faster.
There is however a quality decrease. 50 passes on teamrender where noisier than 12 passes rendered on my main machine only.

Should be no quality difference - if there is, I'd start a bug report thread, with as much info as possible (including the scene, details about the machines, the OS, version of C4D, version of Corona, the images you are getting). Just to be sure, you allowed time for all data to be gathered from the slaves at the end, and for denoising to run after that? It might take additional time for that to happen (so the main machine may stop rendering, but still be waiting on data before denoising).
