Hello! I'm having continuous crashes in the scene you see in the attachment. It's a spotlight made by a cylinder, then a cone with a CoronaVolumetric Material applied to it, and a CoronaLight set to Disc for the lighting.
When the Interactive Rendering stars Max crashes, sometimes. In other cases, it crashes after moving the spotlight or changing a parameter in the CoronaLight.
The behavior only happens when the Secondary Solver is set to UHD Cache, when set to Path Tracing it works fine.
I'm working with 3ds Max 2022.0 and Corona 7 RC5.
Is this a known bug? The scene is in the attachments.
Thanks,
Hello enrico.lapponi!

Thank you for reporting this to us, I've reproduced the issue and it will be investigated.

(Report ID=CRMAX-798)

Ok, thank you! Happy to help!

for some odd reason, once I installed RC4 every time i render any scene it crashes, no matter how simple the model is
Fixed in RC6 :)

Is Render to Texture broken with Corona?
Hi,
Please can you provide some more info? For example; what exactly is broken, Corona Version, 3ds Max version and if possible a scene demonstrating the issue.

3ds Max 2022, corona-7-3dsmax-daily-2021-05-20
It doesn't work with any simple scene

please see the link 

Thanks
Fixed in RC6 :)

Checker -> UVW Randomizer (Mesh Element mode, use U and/or V offset 0 to 1) -> pipe to 1. Diffuse, 2. Displacement. Could also not repro any discrepancy in other slots.

Just to add to this one, UVW Randomizer doesn't work correctly when used with a CoronaDisplacementMod - the same (incorrect) randomisation which doesn't match the Diffuse is applied.

Just checking, this doesn't appear to have been resolved - looking at the release notes for RC6 there is something about UVW Randomisation - but as far as I can see it still applies a different randomisation to Displace vs all other slots?

not sure how the new Volume Effect (Aerial Perspective ) Handel other volumetric effects. but here is test using VBD file in CVolume Grid.

Hi,

So far this hasn't been fixed, sadly I don't think it will make it into v7. I believe this issue has been around for quite some time, and fails only when the UVW randomiser is set to mesh element mode.

I will let you know when I have some more information.

Thanks,

Rowan

Would be more than happy to wait for a final release if this gets fixed.  It's really important on things like floors, tiled walls, cladding etc made with floorgen

Hi Meda,

Unfortunately I'm not able to reproduce your issue. Could you please send us your scene so we can investigate it?
And also, which version of Corona and 3dsMax are you using?

Thank you in advance,
Kris

Agreed - didn't have this problem with UVW Randomise in v6, and it's frustrating that this broke in v7 and doesn't sound like its getting fixed.
At this rate I'll be skipping v7 and hoping this is fixed in v8, not ideal.

If it was/is working in v6 but it's broken in v7 then old v6 scenes rendered in v7 will not look correct, is that the case? If so that will certainly need fixing, I agree. We rely on being able to re-render scenes correctly all the time, sometimes years later. Naturally certain shading things might be different, that's fair, but fundamental texture mapping etc. must be retained IMO.

If it's been around for quite some time, then all the more reason it should be fixed so we can use the feature properly/to it's full potential

Hi Guys,

For the record UVWRandomizer in mesh element mode did not work with displacement (2.5d or old) in v6 or in v5 and older.

The other modes in the UVWRandomizer do function correctly with displacement.

If you can show me a scenario where this worked in v6 and is broken in v7, please do so and I will look into it immediately.

Thanks,

Rowan

Then there is no other option but using exactly that software version which was used to create the scene originally. Many features will change, just think of post processing in v8 and what that means to the resulting image(s).  You cannot expect to get 1:1 results in future versions, but fortunately we can use the Corona multiloaders to easily load an older version side by side for that reason (amongst others).


Good Luck



Never underestimate the power of a well placed level one spell.

You only quoted the first half of my message? That's why I said that "Naturally certain shading things might be different, that's fair, but fundamental texture mapping etc. must be retained IMO". Of course certain things will look a little different a version down the line, but not mapping or other fundamental things that are down to artistic choice.
