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.

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.

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.

+1, makes sense and saves time!

[Max] General Discussion / Re: ACES Color Space

« on: 2023-10-17, 19:20:03 »

But the same would've happened with Filmic/Reinhard prior to ACES in Corona.

There was another thread where the request was to apply tone mapping as a display transform only so the saved data would still have the full dynamic range.
Obviously, this means that the image you save has no tone mapping applied, essentially disabling the entire tone mapping post section... you can't have both at the same time.

Did you try with the 4K cache instead of UHD?

Glad you found the culprit, will add this to my list of "Murphy's Law and how it applies to 3dsmax" :D
