@Ga18bo03 2 года назад

Thanks Will, I tried this effect over and over again and I tried to recreate the prism experiment with the physical properties of light. But the properties of the material weren't working. Great tutorial, thanks

@WillGibbons 2 года назад

You tried following along with this tutorial and are still having issues? Or you tried before watching this tutorial? What specifically was not working?

@Ga18bo03 2 года назад

@@WillGibbons I tried it before watching the tutorial. With your material setup it should work perfectly. When I first tried it, I was also using Dielectric, but I wasn't sure about the difuse color, nor the abbe value. The ground plane tips are helpful as well.

@muhaY-vb5vp 2 года назад

funny how keyshot never brought up this 'dialectic' material, its so costumizeable and amazing result! many of us stuck with glass/glass solid material.

@WillGibbons 2 года назад

Hmm, well, it's there, just depends on whether you need it or not. They've had it for a long time.

@ericlehnert8404 2 года назад

Is that the Codex Leicester opened on the shelf to your left?

@WillGibbons 2 года назад

No, it's a big book called NASA Past and Present by Benedict Redgrove. It's a gorgeous photography book that is too big to fit on my bookshelf, so it remains open and on display, offering me inspiration throughout the day.

@13:08, if i turn off the ground plane, i get the spotlight effect [ we turned it off by deselecting ground illumination] ; instead of an all black background. Did you made any changes to the spotlight [plane] so that we do no see the spotlight effect and just see the object which is all lit up?

@WillGibbons 3 месяца назад

I'm so sorry, I've read your comment a few times, but I'm having trouble understanding how to answer it. Can you ask the question in a different way by chance?

@Sabertooth93 3 месяца назад

@@WillGibbons No worries. Let me rephrase it. @10:56 you disabled the ground illumination option of the ground plane to turn off the spotlight from getting reflected off the ground. Later on in the video, when you are trying to fix the overexposed areas of the meatball, you disable the ground plane [@13:08]. When I tried doing that, what I get is the spotlight effect getting reflected from ground instead of an all black background with no caustics as shown in the video. Also, later on when you disable the spotlight, both the objects are fairly illuminated, whereas in my case they become underexposed. So, are there any additional changes that you made to get the desired output? I hope this clarifies my question.

@jacks19822 2 года назад

what about the Tempered glass (green or blue tint on the edge, I tried playing with transmission (in/out) color, transparency distance, it's never perfect.

@WillGibbons 2 года назад

This can be done with the solid glass material as well (no need for dielectric), but just set the green color you want as the glass color and then adjust transparency distance and that'll produce the effect.

@jacks19822 2 года назад

@@WillGibbons Thanks a lot, I got it sorted. almost realistic. The material I used was solid glass as you mentioned, transmission at 253, 255, 255. Lighting is roughly 75degree angle from flat surface, at 4003K colour temp. I then used interior mode with caustic turned on, at 32 ray bounces.

@guantingzhou8388 2 года назад

Which is better for rendering, AMD or Intel?

@WillGibbons 2 года назад

It doesn't matter. CPU specs (speed, core count are what matters)

@begin-gd1jm 2 года назад

can i only render reflection on the ground?

@WillGibbons 2 года назад

Not exactly. You would need to render out all the render passes and layers and use them in photoshop to isolate the ground.

@begin-gd1jm 2 года назад

@@WillGibbons wow thanks for the tip.
