[Max] I need help! / Re: Direct Visibility Override Color Issue

« on: Yesterday at 11:31:22 »

Im sorry that I've taken your time. It seems some weird stuff happened. Turns out it was just a fluke.

I used Corona Cleaner to clear everything that the utility allows. Scene has not only become noticably responsive but the visibility override started working as it is.

Thank you

[Max] I need help! / Direct Visibility Override Color Issue

« on: 2025-07-14, 16:55:58 »

Direct Visibility Override Color other than black renders object washedout white. There is an HDRI map in Render Setup dialog,  Scene Tab - Scene Environment Rollout - at Single Map Slot.

I remember Override Color only changes the background color in older versions of Corona. Has anything changed? What might have I done wrong?

[Max] I need help! / Re: Strange Corona Camera Track Name

« on: 2024-10-18, 15:11:40 »

Looks like you have applied a look at animation constraint to Corona camera and this is the track for animating look at constraint. If you have not applied such constraint then maybe you can share the steps you did?

There are text objects in the scene having look at constraints to look at this camera, but their tracks should be in the text object tracks, shouldn't they?
Camera object looks at its target.

Corona camera object has two animatable tracks containing a name with strange characters. Any ideas what are these?

I have searched in the forum threads and I thought it has been sorted and planned to be implemented in some future version.
Thank you.

[Max] I need help! / Problem with IFL Files on Corona12 HF1 3dsmax 2024

« on: 2024-09-23, 13:22:54 »

I need to assign a panoramic animated background via IFL format. I also need the background blurred so that no detail is identifyable.

3dsmax Bitmap works with IFL but Bitmap blurring unusable. Corona Bitmap on the other hand works perfect in terms of blur filtering but it did not work with the same IFL file.
 
Please check the attached image. Corona Bitmap displays an error on the material editor panel.

"Could not load texture file...."
"Texture source's content type not specified."

I can blur the image files in a video editor, but it will add to the work and fine tuning will take more time.
Is there any workaround to this?

[Max] I need help! / Re: Are there any changes in Autodesk Physical Mat. Interpretation in Corona HF1?

« on: 2024-09-16, 15:51:12 »

Scatter value had no effect in both versions, so I checked each parameter one by one. Transparency is also set to 1.0 and that seems why Scattering has no effect

SSS and translucent  materials  (may be some transparent materials, too) really baffle me at times. I tried to achieve a similar color with the new version. Red Scatter color displays a complement color (Like cyan) and cyan shows a reddish tint. This used to be like this in some of the ancient max materials, too, (like raytrace material) so I used to think it is something about the actual physical behavior of those materials.

I avoid using these not just because they are CPU intensive but hard to control.

[Max] I need help! / Are there any changes in Autodesk Physical Mat. Interpretation in Corona HF1?

Hi,

I'm working on a medical animation and some of my materials were Autodesk Physical Material. We've had a weeks break in the project so I decided to upgrade all  PC's in the office to hotfix 1.
After a week, I have opened the latest files of the project and to my surprise, my reddish transparent material was simply frost white glass. Actually all my Physical materials have become somewhat different. Skimming through dozens of copies and backup files, I couldn't find a single max file with my original reddish glass material. I decided to look at the files on the only PC that doesn't have the upgrade just in case there might be some backups and the only scene file on the computer opened just fine.
I took the files to the other desktops and that is when I realized its about the upgrade.

You can see in the attachment both versions of the same material.

Luckily I 've had a PC that I haven't yet updated. Is there a simple workaround  option button to revert the Physical Material effect to the previous version.

I needed the physical material for seamless fades between different material effects and the material properties are already animated.That's why switching to some other material is risky.


Edit: The Scale parameter under the Scatter Color seems inoperational in hotfix 1. It renders as if Scale value is set to 0.

It is already enabled. The current problem is with planar mapping. I need it to scale down from one side but it creates a clustering effect 2 clusters in two opposite sides. Probably a very simple setting will scatter equally but couldn't find yet.

Thank you. :) It works, yet I still have a problem.
The standard density I need is in the image. Switching to Map mode changes the distribution density and in order to gradually scale with a gradient, I can only think of creating a UVW more than double the size of the sphere make one half normal density and the other half scaled to zero  There will also be  a gradient area enough for the transition.Can't achieve the look I need.
How can I keep the density int the first place. Any tips?

[Max] I need help! / Re: After rendering is done a image i/o error appears and doesn't save renders

« on: 2024-06-03, 13:04:34 »

It might be related to a couple of reason, having the same heading, can't write the file for some reason.

I've had the issue once with PNG files, apparently due to "some corruption" in the PNG I/O plugin.
It might happen simply because the program can't access any of the folders it has to access at the time of saving. Not only the output files but sender elements or God knows, whatever configuration file that has to be read or written and can't succeed.
The frame of such errors can be so wide that you can experience things you can never imagine. (Even the folder name length exceeding 256 characters cause problems or some Unicode character that doesn't represent a valid equivalent for the OS.)

3DS Max Batch system is also not so intuitive. I enter parhs, file names but at the end of the day, find some XXCamera _View 01 like naming scheme which I could never figure out how I have achieved that.

This is very probably Max issue, and in the Vray instant, you probably didn't have the same thing causing the problem.

[Scatter] I need help! / Scaling Scatter Instances Keeping Positions Fixed

« on: 2024-06-03, 12:43:25 »

As the title implies, I have a sphere with an animated noise, and a number of scattered objects depicting the spike proteins in a virus. (Title doesn't imply this, you're right. :D)
I need to make the scattered objects disappear as it enters the cell, and wish to scale them down to %0 as they cross the cell membrane.

Tried the Map mathod, with a max Gradient Map. My instances start to move as I move the UVW Map gizmo. Tried to achieve the effect with slice modifier, No go.

How can I resize th instances from one side to the opposite side to 0%, without changing the instances' placement?

[Max] Bug Reporting / Re: Degraded Performance with Chaos Scatter Doesn't Restore by Hiding

« on: 2024-05-20, 13:46:37 »

It is possible that this may as well be not related with Corona Scatter itself, but 3dsmax trying to calculate something although it is hidden.
This behavior makes me feel uncomfortable starting a new project in 3ds max.

This happens from version to version. Once groups were causing stuttering playback and hiding objects was not helping regain the performance. I remember a version that solved it apparently. I presume Autodesk had disabled most refresh routines in that version. Some things weren't updating  in realtime but reflecting the result after doing something else.

[Max] Bug Reporting / Re: Very slow geometry phase 10x slower than old pc

« on: 2024-05-18, 11:31:25 »

This is a frustrating but expected result, as @Pokoy stated, the more cores a system has, the slower single threaded operations will be.

I vaguely remember an old CPU single performance chart from Tom's Hardware website.

With a list of many high end products starting from 1 core 1 thread Pentium 4 3gHz, this CPU was the slowest of all processors in multicore benchmark and number fastest in single threaded.

I also experience this a lot and makes me feel pessimistic about our profession. That's why I work with my 4 Cores laptop until it is rendering time. It is definitely more responsive during viewport operations than the 24 Core Xeon one.

[Max] Bug Reporting / Degraded Performance with Chaos Scatter Doesn't Restore by Hiding

« on: 2024-05-18, 11:08:45 »

I report this issue, assuming that hiding a scatter object would turn off its calculations.

I have a virus model, a geosphere and two highly detailed spike protein structures scattered on the surface with a total amount of 62. Sphere is also animated with noise modifier.

A slowdown during viewport playback is expected and experienced. I can't restore the perfomance by hiding all components of the scattered model. I have also tried to delete the noise modifier.

Deleting the the same hidden objects reverts back the playback performance.

Performance change is like from 80 fps to 10 fps. (approximately) File is in the attachment.
