I cant see any way that it can be calculating physically correct caustics that quickly and the fact that you can art direct the caustics makes me think its totally fake.
I notice that thers no side by side comparison with actual rendered caustics vs the shader.

32
This has to be some sort of fake shader effect no?
It looks very good regardless.

I seen one recently on FB from an artist named Matt Hallett. Apparently using the technique 'in-painting'. Think you can find his page under: Matt Hallett Visual

This was his before Image

This was his AI replacement

Ive been following those too. He is charging for a few courses on how to do it but id like to hear from others whether the pricetag is worth it.

[Max] Feature Requests / Re: Mapping source for CBitmaps

+1 Always annoying having to adjust parameters of multiple bitmaps for a PBR material.

I would add that it could be useful if this node could be applied as either an override mode OR a multiplier of sorts.
i.e. if i have a material set up with differing tiling settings WITHIN the bitmap nodes, this node should either override the bitmap option OR act as a multiplier and keep everything in the correct relationship if the bitmaps dont necessarily all have identical settings but you want to control all of them in one place.

[Max] Feature Requests / Re: Select Denoiser for IR

+1 for this. It would be great if there were some settings we could change from within the VFB such as overrides, global volume mtl, denoiser etc

"Turn off translucency for all materials that start with veg in front" - done
"Select all objects with more then 500K polygons and generate proxies for them"


ChatGPT is ok at maxscript.  It could probably produce snippets for you. This isnt really a corona thing its a Max thing.

I had wondered about the way AI could change rendering specifically and i wondered if we could end up with specialised models (the ai kind) that are hyper specialised packages that know how to render a specific object or surface style very very well. It could understand placement data from the 3d scene by using very basic placeholder objects for layout. Understands where the camera is, and lights are. And then uses lots and lots of specific stable diffusion models to generate the final image knitting it together mask by mask like an ID map.

I agree the new DOF highlight Solver looks great!

This is very cool. Cant wait to see what people create!

Is there any way to set up any of the corona passes to highlight complex materials?
Would be super useful to be able to do like a false-colour pass to identify shaders causing slowdowns.

There is!

You can use the CInfo_TimePerSample element for this - https://docs.chaos.com/display/CRMAX/Render+Elements#RenderElements-CInfo

Ah fantastic, for some reason i assumed that was a render stamp type pass.

Just a tip:

If you can use one of the Sini tools called Sini Forensic, it can help you scan your scene and provide you with an overview of problematic issues present in your scene.

Yeah thats my first step every time and the file isnt showing anything problematic.

Hardware / Re: Computer spec 7950X with 192 of RAM?

Exactly! My current "mobile-PC" I built is based on Cerberus-X which houses ATX board since I needed 4-DIMMs. Technically I could have used m-ATX but almost none exist and 99perc. of SFFPC cases are Mini-ITX or few ATX/E-ATX ones.

With 2 DIMMs, those Mini-ITX SFFPC cases are finally doable even for professional mobile workstation. Ideally the flat&thin "console" style (like Fractal Ridge) since those are easier to put into backpack, rather than the "Sandwich" ones which are smaller but thick like a brick. But cooling is still a bit issue for CPU there.

The thing is, the laptops are very close in performance to these PCs now, just 5 times louder :- ). But still much more practical for travel. (though not for dollar value and upgradeability).

Ive been tempted a few times by a workstation laptop but i like the idea of upgradeability or at least being able to potentially take parts from my main workstation like GPU, RAM and storage, and put them into a portable PC.

43
One thing i have noticed though is that even when i hide the imported objects, the slow rendertime stays there.
If i dont import it, the scene renders fine.

What if you delete those objects instead of hiding them, does it affect render time in any way?

As i track down the cause, i will test this out.
The railclone tip above helped with the parsing but my UHD Cache is still multiple minutes long so ive got some digging to do.

even small 2-dimm ITX boards can now have 96GB ram. So let us know how it goes.

well damn i hadnt even considered this!
Small form factor travel-ready render PC can be a reality!

In general, hide half the objects and render. Still slow? Hide half again and repeat. If faster on the first halving, switch which half is hidden and continue as before. This should identify objects or materials, and once you pin it down, you can investigate why.

You could use material overrides too, usually worth enabling that globally and see if magically everything gets faster as then you're most likely looking for a problem material. You can still likely track it down with the steps above (probably easier than using exclusions to the material override).

Material override isnt something ive considered before so thats a good one to try early on thanks Tom.
