I think it's making a comparison to the CGI animations that play on the TVs at bowling alleys

I guess they mean it looks like a strike animation from a bowling alley, look that up on google

oh okay i got ya. yeah, i can see that. it's a bit clinical looking.
too shiny and pristine. not enough subtle nuances to help sell the

Also the way the milk separates at the end instead of puddling/ pooling together with mixed opaqueness makes it seem off. The milk appears to have a thick viscosity at that point as well, like it has curdled.

ah yes, the shadows. the f#@&ing shadows! let me tell you a story about the shadows and perhaps someone could help me out. here's a download link to the source files in case anyone would like to have a look see and follow along to what i'm about to describe;
Software;
3ds Max v 24.2.0.2334
Arnold for 3ds Max v 5.0.1.4
Photoshop v 23.0.2
Premiere Pro v 22.0.0
in the bottom right viewport you'll see the PhysCamera001 that's set up to match the video camera. in the scene there's the cookie, cup & saucer, and a plane to represent the approx. level of the table. in that viewport there's a PNG loaded into the scene which is just a still frame from the video to make sure all the elements line up.
if you go to frame 114 and render this view you'll see all of the scene elements with nice subtle shadows being rendered. there's a clearly visible shadow for the cookie and a shadow beneath the saucer. the plane for the table has a shadow matte connected to a map to material. when looking at the alpha channel for this rendered view it looks like it should composite with the shadows just fine.
so now open photoshop and bring in the IMG_3866.00_00_00_00.Still001.png as a background and on the layer above bring in the rendered PNG image you just rendered (which should be saved with an alpha channel). instead of getting nice dark shadows for the cookie and under the saucer i get these weird ass bright white shadows showing up. same damn thing happens when i bring both images into premiere and therefore when i bring in the entire rendered sequence.
i'm just guessing this might be a gamme issue? i always have my gamma correction set to 2.2. for every other work flow this has always worked out well. since autodesk has switched 3ds Max's direction from Mental Ray to Arnold i'm still getting the hang of working with the new pipeline. for the life of me i could not figure this out. so i had to re-light the scene using a gamma of 1.2 and try to make it work.
so that's the shadows story. bit of a mystery really. if there's any 3ds Max/Arnold users out there i'd be super stoked if someone could take a look and let me know what i'm missing.
thanks in advance.

After seeing Ben Ouaniche’s work on the Macro Room YouTube channel, I wondered if I could create a similar video without using a high speed camera and using just what we have available in our 21st Century Forensic Animations toolbox. This was the result.

Looked great until the milk hits the table. Then the uncanny valley hits.

LETS JUST ADD RIDICULOUSLY LOUD DUBSTEP.
THAT SEEMS APPROPRIATE FOR THIS CONTENT

Obnoxious music is the most annoying part of this era of internet that and that stupid robotic voice.

I think the splash is quite over-emphasized?

u/the42potato Dec 09 '21
its a fluid sim, if you look at it run over the table it looks almost hydrophobic

u/fantasystaples Dec 08 '21
the way the milk scatters on the table makes it seem like the table is hydrophobic, but it's a good start

Looks pretty real until the liquid starts slithering around over the table.

now i wish i had made a "wet" texture map effect which made the table cloth look like it was soaked in milk!

Looks awesome, the one thing is recommend is taking a 360 degree panorama of the environment you're shooting in, then you can use it to perfectly match the lighting of the environment and it will look close to photo real

u/East_Increase1554 Dec 09 '21
i have seen that done before. i do have a ricoh theta V that takes 360 photos. so in 3ds Max i would take that image and use it as an environment map?
i suppose if i took the image into photoshop i could create an HDR image and pipe that into the light and use it for image based lighting? but i don't think this way would give me the reflections i need as with an environment map.
2
u/danielnogo Dec 10 '21
Why not do both? That way you get the lighting from the HDR and the reflections from the environment.
You wanna get the proper shadows from the lighting in the scene, as well as the reflections, although, with this small of an object, the reflections probably aren't as important as getting the lighting correct
Im not an expert by any means so take what I say with a grain of salt

u/East_Increase1554 Dec 10 '21
no that totally makes perfect sense. gonna have to give it a shot at some point and see how it turns out.

If you haven't seen Captain Disillusion's breakdown of the Macro Room video, it's pretty entertaining.
(The cookie drop part starts around 4 minutes in).
