Porting and API / Corona Image Editor alternative?

« on: 2025-03-20, 17:13:49 »

My understanding is that only users with Licences can use CIE?

Even if I'm incorrect, for someone to use a CXR file (in it's full capacity; light mix for example) it still requires non-corona users to install CIE, right?

I'm wondering if anyone has built either a web-app or simple CIE-light app that can allow a client of mine to play with my rendered light-mix?

If not, how difficult - with intermediate skills - do you think it'd be for me to build a web app to allow for light-mix capabilities similar to that in CIE?

General CG Discussion / max 2025 selection of objects goes wrong

« on: 2025-02-13, 21:40:28 »

This is 3dsmax related, not Corona. So off-topic, I know, but I'm certain this is a new 'bug'....I'm wondering if anyone knows why this is happening to me for the past few months?

I try to select an object and it selects the bigger, more simple object behind. Every damn time.

In the video below I'm demonstrating that I want to select the sofa (which has many more edges) but the BASE object (behind/underneath the sofa) is constantly selected - which is unintended, of course.

It's extremely frustrating. What have I done to cause this?

Any help MUCH appreciated! :)

[Max] Bug Reporting / [SOLVED] Error with denoise + volume material

« on: 2025-01-27, 16:57:54 »

Not sure if this has been reported yet or not, but see the attached image. I get this weird discoloration after denoise happens on my render. The whole scene has a basic cube with Corona Volumetric Material applied, if I hide this box, the error disappears.

Never seen this until recently. Additional info also supplied. (I know, I've got kinda crazy camera tone mapping settings applied - it's for an unusual project!)

Cheers,

General CG Discussion / 3dsmax - add a note to an object?

« on: 2024-11-29, 10:15:35 »

I'm wondering if any of you smart folk out there know a good way to add some sort of note or helper to an object?

Ideally, it should be a little keyword, or arrow, or symbol that is always 'attached' to a mesh. I don't want it to be grouped, as this gets messy quickly, and I don't want to link it to the object, as that's a separate object entirely and won't copy across when I duplicate said main object.

I guess in an ideal world it would be some splines that are a separate element within the object, but as far as I know, it isn't possible to have curves/splines within a mesh or poly object.

Any tips out there? I'm modelling a big apartment building with a set of standard window sizes and want them to be labelled (for my own internal 3dsmax use only - so it doesnt have to be pretty).

Thanks!

General CG Discussion / 3dsmax invert

« on: 2024-11-27, 08:26:46 »

**Not corona related**

In 3dsmax...

I can do ctrl + i on an edit poly modifier to invert the selection, but I can't do the same when in edit mesh mode. Why?

It seems I can't set this hotkey to the edit mesh either. Why?

Any help much appreciated :)

[Max] I need help! / Corona Bitmap file open dialog not opening

« on: 2024-10-04, 17:09:43 »

Just updated to 2025.1 - I vaguely remember reading somewhere something about coronabitmap not working with this version? Am I correct?

I can't open the file load dialogue from corona bitmap node settings in SME.

I guess this is a known bug?

General CG Discussion / 3DSMAX DISABLE "MISSING EXTERNAL FILES" ON LOAD

« on: 2024-10-03, 21:34:23 »

Does this warning on the file load bother anyone else?

I really don't care about these missing files, and they're usual false positives anyway seeing as it doesn't like loading Corona pre-set materials for some reason.

Does anyone know of a friendly + easy way to globally disable this warning on the load?\

Thanks!

[Max] I need help! / Crash on SME load

« on: 2024-09-30, 19:03:00 »

I'm currently experiencing a very, very, annoying problem. It seems to affect almost all scenes, on all projects at the moment and it's killing me.

It's not necessarily Corona related (I actually suspect Vray)

I load a file. I open Slate Material Editor and then an instant crash.

I re-open the scene, open SME and almost every time, it opens fine.

However, this problem has recently evolved. Now I open a scene, load SME and it doesn't open, the whole program just completely freezes. Nothing.

I have NO idea what's causing it, and no idea how to stop it.

Has anyone experienced anything like this before?

I'm on Corona 13 Daily July 30 , Max 2024.1, Windows 10.

One note; When this happens I check Task Manager and 3ds Max has has multiple instances of 'Microsoft Edge WebView 2' open. What is this? Is it possibly related?

Thanks for any debugging tips!

[Max] Daily Builds / PNG Library Internal Error

« on: 2024-08-13, 17:20:15 »

Hi,

I'm getting this error when trying to save a second PNG beauty pass. (see attached error)

It's being managed by Pulze SM, so not sure if it's a fault of that plug-in or not though... (I have it set up to save as a JPEG but also save out another pass as PNG)

The PNG file fails to save, obviously but the JPG saves fine.

[Max] Bug Reporting / Bloom + Glare errors in animation frames

« on: 2024-06-20, 21:36:37 »

Can anyone tell me why this is happening? And how to fix it?

Some frames render with either wrong or off-color bloom+glare.

Often I'll render an animation with visible corona lights and this flickering will happen on *some* lights.

This has plagued me for quite a while, so I don't think it's specific to this version.

Thanks!

[Max] Bug Reporting / Cosmos material import erorr

« on: 2024-06-17, 16:11:45 »

Hi,

Just a small error. If I import "Wall Paint Fine Grain 01 White 100cm" the textures do not seem to come with it. 3dsmax + windows 10.

It clearly has textures in the preview... so not sure what's going on. Other white wall plaster materials import fine.

Off-Topic / Internet in basement?

« on: 2024-05-30, 11:20:01 »

I know this is way off topic but I come to the Corona Brains Trust once again...

I'm hoping to put 2 of my PC's down in my basement. It's nice and cool and dust free.

Home office with 3-4 PC's is just too noisy and hot, I want to clean things up a bit. Obviously I need to have internet access down there. It doesnt necessarily have to be LAN, I'm toying with the idea of a VPS if I can get a 2nd reliable internet connection down there.

The basement is approx. 30m away from my apartment. It's 1 floor down but not directly underneath me. I live in an complex of 6 apartments so there are other basements (aka storage rooms) down there too. Access is through 2 heavy thick doors. I can't simply stretch an ethernet cable down there as that'd piss off the neighbors.

My current solution is working but it's rather limited. I bought a new 4G SIM and have it in a cheap Huawei 4g wifi router. In the basement I get speeds of max 50mb download and max 3mb upload. The upload speeds are killing my productivity.

If I take the same router outside, right next to my entrance I get 160/60mb down/up. These speeds would be totally fine. I tested my phone in the basement on the same 4g network and got the same speeds (50mb/3mb) - so I'm not sure buying a new router will help much? Bigger antennas maybe? Maybe I can somehow weave an antenna out of my basement door incognito? I guess 5G will be even less likely to penetrate the basement walls?

My first thought is to use a powerline adapter. But I have no idea if my power is shared between my own apartment and that in the basement. Even if it is I still have no way of knowing if a powerline adapter will work though all the building circuitry. I doubt that the power down in the basements is communal though so I don't think the neighbors will be paying for my PC's to render 24/7.

I asked my building manager if my power is shared between my apartment and the basement but he kind of refuses to answer me as he's convinced I'm trying to build a crypto mining setup down there. We rent, rather than own so I can't go drilling any holes or anything...

The walls are concrete. My basement room is buried in the middle of the building but one of the walls is the concrete exterior wall. I'm astonished that I get reception in there at all to be honest but it does work fine for downloads.

Am I out of options? Is there anything I'm missing?

Many thanks for any ideas!

[Max] Bug Reporting / MultiTexture odd behaviour

« on: 2024-05-07, 21:46:17 »

I used to do the 'batch add textures' to the multitexture node and it would automatically set the number of slots.

Now, if the number of bitmaps I select is less than the number set it won't remove those empty slots.

I recall this used to work correctly. Right?

[Max] Bug Reporting / Linked objects and Decal

« on: 2024-05-03, 16:14:35 »

I'm sure this must've been reported already but it seems that I cannot apply an exclusive decal application to only a single object which has other objects linked to it.

I doubt it's intended to work this way, so it seems like a bug to me.

Happy to try to reproduce if it's not easily done so by devs.

Hardware / PC Diagnostic software recommendations?

« on: 2024-04-15, 20:23:27 »

My PC is causing me trouble. It's almost always had problems but I've just dealt with it. I'm on the verge of buying a new one (it's time anyway) but right now I just don't want that worry.

I'm wondering if anyone has good software recommendations to help pinpoint what the issue might be? I'm often getting the blue-screen crash, a memory load dump, if I recall correctly.

It's generally gotten pretty bad over the course of approx. 2 months to the point of being unusable at which point I replace the windows SSD and things seem to work all fine again. But this time it hasn't helped. I'm now thinking it might be my graphics card. I've replaced the RAM. I thought the RAM was a real problem as the PC could never handle 128gb of RAM, so I've always only had 64gb installed with another 64gb sitting on my bookshelf collecting dust.

It generally happens under moderate-high load, but sometimes not.

My full system:
CPU: AMD Ryzen Threadripper 2990WX
GP: NVIDIA GeForce RTX 2070 SUPER 8 GB
MB: Asus Prime x399-a
RAM: 4 x 16gb DDR4
SSD: Samsung 850 Evo 500gb

Any tips in pinpointing the problem appreciated!
