[Max] Resolved Feature Requests / Re: Physical camera to corona camera

« on: 2023-11-20, 16:31:35 »

maybe this is what you need
https://d95design.com/product/camera-converter/

Hello.

Is the way to convert a physical camera to corona camera to add a CoronaCameraMod? Or is there a script?

Also I have over 80 cameras in a scene. Is there a script to add the CoronaCameraMod to all of them automatically?


Thanks

Just bought this, installed it and tried to run it, but when the script launches it immediately closed max (2024) as it was detected as malicious software (by Autodesk I think). Have you/anyone else come across this?

As far as I'm aware you can disable the 'security tools' in Max - there's an entry somewhere in the top menu. You might be able to run it once they're disabled, of course this comes with the 'on your own risk' disclaimer...

[C4D] I need help! / Re: smooth shading

« on: 2023-11-20, 15:47:09 »

This issue is not because of smoothing/normals.
It is because you are comping the elements in PS in 16bits, which results in too coarse color values, which will inevitably produce banding in dark areas. You have to use 32 bits in PS.

When you save out elements, you need to make sure to use 16 (or 32) bits in an HDR floating point format - for example EXR.

HDR formats can use 16 or 32 bits, both will work for you, just use EXR. HDR formats save values as floating point data which is needed for increased color value accuracy.
Note that this is *not* the same as using 16 bits in LDR formats such as TIF/PNG. These LDR formats use integer values which have limited accuracy. This is what you're seeing - either because you saved elements to a integer LDR format or because you're working in 16 bits mode in PS (or both).
In Photoshop/After Effects, you have to work in 32 bits (it's always linear) mode when comping elements.

[C4D] Bug Reporting / Re: CoronaMappingRandomizer is not so random

« on: 2023-11-17, 19:52:49 »

Have you heard the story about how Apple had to change their random song playing algo on the iPod, exactly because of the same effect: even in truly random sorting the same instance/color can appear numerous times in a row. Making sure something is not repeated is not true randomness. But I agree to some point, it looks wrong especially with texture maps or colors.

If I'm not mistaken PS won't open Tifs from CIE when they're 16bits with alpha. Try different options and see if that helps.
Tifs from CIE always have been handled differently in PS, not sure why. I reported that a while ago but the answer was they work as expected in other apps so no need to check.

General CG Discussion / Re: 3D Gaussian Splatting

« on: 2023-11-13, 14:06:45 »

Yeah, was wondering this too, especially since setting this up from actual 3d data might be more accurate, I guess it could help to some degree with slight changes in animations without the need to re-render everything.

FWIW, here's a thread over at Chaos forums asking basically the same question, but don't expect too much:
https://forums.chaos.com/forum/v-ray-for-3ds-max-forums/v-ray-for-3ds-max-wishlist/1193659-3d-gaussian-splatting-in-v-ray

I wouldn't wait for Autodesk, their 'evangelists' are probably trying to come up with a way on how to get rid of expensive 3d dev and somehow utilize AI and be done. Their approach seems to be adding 1-2 modifiers per release cycle, adding stuff no one asked for and fixing bugs introduced while doing so... or not.

[Max] Daily Builds / Re: Tiles playground

To avoid potential disappointment, I can say that we are too close to release to add more functionality at this point. Do keep posting suggestions for features, but do be aware that these won't show up in Corona 11 when you post, but for future development. Thanks!

Isn't this a bit too constrained? It's 2-3 weeks since the map is available for testing and it's already too close to release date to consider feedback. Why not make it the best Tile map there is and release at a later point?

Corona 9 and 10 running, literally, side-by-side. :)

Great, thanks for showing this.

What's new in v10 about the spread parameter? I don't remember seeing this mentioned anywhere...

Julieta - for the devs to have something to work with, it would be great if you installed v9 again (uninstall v10 and all chaos components...), rendered a few examples (and saved the files), then installed v10 and re-rendered exactly the same example files, with identical settings everywhere. Otherwise it's difficult for you to make a point and for the devs to see the differences.

[Max] I need help! / Re: Chamfer Modifier/Smooth to Adjacent - 3DS Max

« on: 2023-11-04, 13:28:48 »

'Smooth to adjacent' uses explicit normals which are problematic in Corona. You could try to set the 'Shadow terminator handling' to 1.0 (I think 0 is the default) in debug/dev tab in Corona render dialog. It might help, although I recall a case where it didn't...

[Scatter] I need help! / Re: How to Attach Crumbs Realistically to a 3ds Max Displacement Map

« on: 2023-10-30, 17:47:11 »

Not sure if Corona Scatter respects render time displacement but it's worth trying first before the workaround I posted. If not, it's a good feature request, there's certainly a lot of use cases where Scatter would need to sit on top of a rendertime-displaced mesh.

« on: 2023-10-30, 16:26:36 »

Hmm, you could copy the cookie mesh, subdivide it to a nice highres version, apply the displacement map to a displace modifier with the same settings (min/max etc., make sure it uses the same map channel as the corona displaced cookie), and scatter the crumbs on that mesh. Then, make that highres cookie non-renderable, this could work.

[Max] I need help! / Re: Diffrence in Corona VFB and ACES OT output when saving image!

« on: 2023-10-24, 11:29:21 »

I got this problem than i have diffrent contrast/gamma output in VFB and SAVE button or Batch Render. Its like it dont apply ACES OT filter. How do i fix gamma input. Everything is on default settings right now(in this picture)

You can not use the Windows 10 (or later) image viewer to compare colors. It won't respect color profiles and add some automatic contrast and saturation.
There's been a lot of discussion on this here on the forum, use the search function for more info.
Basically to get the same colors you have to:
- open your LDR image in PS
- assign the color profile Windows OS uses for your display
- convert profile to whatever you want it to be (sRGB or whatever you want to work in)
- make sure the profile you're using is embedded into the image file when saving
- view in an app that supports embedded profiles and doesn't add its own contrast/saturation punch

The Win image viewer will do things on its own, do not use it to judge colors.
