Corona Renderer 6 for 3ds Max - Daily Builds Discussion

[Chatchawind]

   Some problem I have found since version 5. When I am using Spacing Tool with Corona lights to get along with spline shapes. At first It is fine but If I try to do one more time and just rotate the screen view it always crashes. Does anyone get this problem ?

Thank you !

Hi, I couldn't reproduce this in V5 and RC3. Can you please:
- send a simple scene where this happens
- provide detailed steps how exactly to reproduce the crash (what exactly to click where, how exactly to trigger the crash)
The uploader is in my signature, thanks in advance!

I already uploaded with video recordings and 3ds max files. Sorry for the first video, quality is bad.

Thank you

does RC3 fix the issue or the uvw randomizer makign the render take much longer?

Hi,

To get similar rendering times than in previous versions of Corona you can switch the blending amount to 0 or disable the HQ blending.

Thanks,

Hi. Apologies if this has already been discussed...

There seems to be an issue with the noise level when using regions.

I do a render, which takes 15 mins or so, but when I do a region the noise level says around 4.5% and the estimated render time is 45+ minutes... It's obviously getting confused with the noise in the non-rendering areas...

Is this replicable, understandable?

Many thanks. I'm using Daily Build 21 July 2020.

EDIT: It seems this problem only persists when the full render processes a bit early on, and then during the render I add the regions. If it's rendering with regions from the beginning (ie; from a clear VFB) then it works as expected/properly.

Hi,

I've just been testing this here and it seems to work as expected for me, if I add the region after the render has started it takes roughly the same amount of passes to converge to the same noise level without taking the extra time you are describing.

Would you,
1) Be able to install v6 RC3 and try it in this version? IIRC we also fixed another bug you mentioned in this version :) (You can set the bitmap tiling mode to clamped, in order to fix the artifacts you reported)
2) If the issue is still reproduceable in RC3 can you please archive and send the scene to us with some specific reproduction steps?

Instructions on how to do this are in my signature.

Thanks,

Rowan

Thank you so much Rowan.

Sorry to be a pain, it seems to be working as expected again (in RC3 at least) :) So thanks again.

However, I'm still struggling with the bump mapping issue... I tried with RC3 and changed all the bump map textures to 'Clamp' and the problem persists/is worse.

What exactly is this clamping? Should it be applied to all bump textures? Or all textures? Or only textures that I don't want repeating?

The bumps are often plugged into tri-planar nodes, which seems to be the culprit (as discussed earlier)

Please see attached screengrab from RC3 with clamping set to all bump map textures...

Hi,

So you should just apply the clamp mode to the texture which was set to "no tiling" mode. The rest you can leave as they were, I think in your case it was just the texture containing the sponsor/client logo.

Let me know how you get on.

Cheers,

Rowan

Hi,

This doesn't seem to have anything to do with Windows updates, it seems to have stopped working in the v6 daily build from 2020-06-18. It has stopped working only in 3ds Max versions 2014 to 2016. It functions correctly in 3ds Max 2017 and newer.

I will report this to the dev team and see what can be done, in the mean time you can use the CoronaDisplacementMod. Unfortunately this doesn't give you a viewport representation, but it does render correctly.

Thanks,

Thank you, I will follow the updates!

Hi,

This is fixed in v6 RC4.

Let me know if you have any issues with it.

Cheers,

Hi,

With the last RC4, the curve editor seems to ignore my *.acv file, the curve stay linear. Someone else has the problem ? Bug known ?

Thanks in advance

Hi,

Thanks for reporting this, I was able to reproduce the same behaviour.

We will look into it.

I am still unable to reproduce this crash. Everything works fine, and I am trying to follow your steps carefully, using your provided scenes:
1. Select the light
2. Open the spacing tool
3. Pick the spline
4. Enable the follow option, change the number of duplicates
5. Repeat with different splines, applying the previous result
6. Deselect the original light
7. Move the camera around
8. Deselect / delete / Ctrl+Z
No issues so far. If you have some further ideas how this could be reproduced, please let us know. I will also ping other teammates to try this on different PCs.

Update: we tested on another computer, and no crashes either. I would suggest removing unnecessary scripts/plugins and using a different version of 3ds Max as 2018 is known to be unstable.
You can also use a newer version of Corona (currently V6 RC4) and if the issue still occurs, send us a minidump captured from the crash: https://coronarenderer.freshdesk.com/support/solutions/articles/5000524006

Thank you. I will try different versions of 3ds max.

Is there a known bug when using Corona 6 RC4 and Forest pack?
Experiencing quite strange behaviour  with the following combo - win 10, latest build, 3ds max 2020, latest service pack, Corona 6 RC 4, and Forest pack 6.3.0.

A particular scene just stopped rendering any Forest pack object. If copy any object from this scene into an empty one and then try to populate Forest pack over those objects or any new ones, FP just does not render.
Vray renders perfectly those, regardless of the scene. I will try the same scene with 3ds max 2018 and Corona 5.

Edit: The same scene does not work with Corona 5 and 3ds max 2018 as well. FP just does not work for some reason with this scene.
        If new one - it works, unless merge any element. At the same time Vray handles the scene with no issues. Attaching images.

Hi,

Can you send over your scene so we can investigate?

Instructions on how to do so are in my signiture.

I guess it's either:
- some specific setting in the Forest object
- rendering an orthographic view

i tried installing RC 4 & 5 but my max 2019 is stuck on on launching coronamaxutils2019.dlt on splash screen, reinstalling corona 5 and it works fine. Anything im doing wrong?

Hi,

Can you try running the uninstaller for v5 and then running the v6 installer again?

Also, which version of Windows are you using?

Rowan

[SmurfN]

didn't help. Im running windows 10 pro 1909
