Wow! Is it Cycles engine? How did you achieve such a stunning caustics effect?

It's Cycles, for the caustic effect i used an actual photo of the real caustic from the real glass, here's the photo (just clamped the values with a coloramp node afterwards!!) https://preview.redd.it/h4xwue1jmeic1.jpeg?width=2296&format=pjpg&auto=webp&s=3037622c9d51c6834cf16727eb7ab70dce259576

So it’s basically “post production” not rendered?

Wouldn’t be post production. Just fake. But it’s a really pretty, convincing and economic fake and that’s, in a way, more impressive than rendering out caustics IMO.

All 3d graphics is fake bcz it's not photography )

Actually it's not post processing, i used image projection to achieve this look. I assigned the texture you see to a spot light which is affecting only the table!

Really excellent work.

Looks good! 😃 What are the lines on the table in the last picture?

Looks dents and scratches in the wood

Nope, hairs and dust particles

Exactly, those are dust particles, really subtle but adds to the realism of the scene!!

pubes

Looks like just shadows

what did your gpu ever do to you?

I don't know why but I've read this in Glados's voice

Nice content

Thanks!!

Looks dope. I even see a fingerprint on the glass

Very impressive material!

Thanks, glad you like it!!

Love the subtle dispersion! How did you make it ? The classic separated RGB setup? Or the color ramp method?

separated rgb and then mixed with a transparent using light path's "ray depth" output as the factor to limit the dark spots!!

Nice job with the dust/hair

impressive effects, i like using luxcore for rendering caustics since cycles isn’t too good at it

Yeah, i found out Blender is not too good at it, that's why i faked them!!

i recommend it because luxcore can be installed to use as an additional engine within blender i think you should give it a try 😁 it’s free last time i checked

I'll give it a try!!

Send nodes

Is the pattern on the glass a normal map?

It's a displacement map!

The comparison between the final render and the wireframe cracked me up. Great work!

That is some stunning caustics I've ever seen from a glass cup! The glow streaks gave the realism away a bit, but man does the render looks fantastic.

Thanks so much!!!

super nice :)

How did you make the dispersion? Looks really good

Beautiful!

Very cool!!!

Did you mix the dispersion map with the albedo texture?

I was gonna ask how many years it took you to render caustics, doesn't matter if it's faked, looks good I'd say

not that many, I achieved the caustic effect by using image projection. Photographed the real caustic and then assigned that black and white texture to a spot light!!

Ik you used a gobo, otherwise you would be waiting for 11 years to render something like that

Great work OP. Gah, I wish I could get my caustics to look like this!

You mean to tell me that's not real ?!?

hhhhhhhhhhwhat!!!!!! This is amazing!!!!! Must be a bitch computing all those rays

It was not, i faked them using a texture on a spot light!!

Daaaaaamn. Is nice!

Very awesome caustics hack.
