How to Render a Cloudy Plastic Material in KeyShot 8 

Thanks Sam!

Wow, thank you!

Hey Vineet! My pleasure. Glad you enjoy!

Cheers!

Thanks for taking time to comment! I'm glad you like the video format :)

I'm glad you dig it!

Thank you, Kaymar!

Thanks Rupert! That means so much to me. It takes quite a lot of time/resources to make videos regularly and when I worked for Luxion, much of my time was spent traveling and doing on-site training, which didn't leave much time to create videos every week. I've chosen to make this a priority of mine since I have complete autonomy over my time now. I'm glad you like them.

Not a problem. Glad you liked it. Cheers!

Hi Lee, thanks for the comment!

I think it can look really nice if you dial it in.

Cool. Yeah, not sure when or how I want to tackle that one because it's very nuanced and could potentially be a very long video.

My pleasure!

You're very welcome!

Awesome!

My pleasure!

Glad it was helpful!

Thanks :) This means a lot to me!

Of course!

Awesome! Thank you!

Awesome, thank you!

My pleasure!

You're welcome!

Sweet! I'm glad to hear, Grishma!

haha, too kind!

No problem!

Haha, I'm not against profanity. Just need to keep my YT channel family-friendly :) Glad you dig it!

You are welcome!

The pleasure is mine! :D

Hi @@WillGibbons, I would like to render without a background so I can change it later on in photoshop. With png format the background colour is still visable through the part, do you know a way to fix this?

@@jipjip8594 Hi. Nope. There's technically one way to do it with keying, like a chroma key using bright colors and doing a replacement... but it's very manual and not easy. You're much better off just rendering it on the background you want. This is just something KeyShot can't do because if it did, the material would not be technically accurate and it's how KS render engine works. Sorry!

You're so welcome!

Sounds like someone needs a new computer! :P

Cheers!

Rock on, man!

Glad I could help!

You're welcome!

You’re welcome!

That's awesome!

Thanks for this awesome comment! I really appreciate it. Best of luck on your professional journey.

Thanks!

Jelly, huh? haha. Whatever gets you excited :P

You're welcome! That was a bit tricky, but certainly helpful I think!

Of course!

Great question. I'll be creating a video going over the books I own that are rendering related. Stay tuned!

@@WillGibbons I couldn't find a video on your books, so would you mind sharing the title of the book you've used here? Many thanks in advance.

@@WillGibbons Actually, don’t worry. It’s "Real-Time Rendering: Fourth Edition" by Tomas Akenine-Möller

Yeah, that’s typical. You can try increasing material samples. If you’re using KeyShot 9, use the denoiser, which helps a ton! Otherwise, I think I rendered my to 2 or 3,000 samples. Yep. This material can take a long time.

I'd probably just use a glass material and reduce the IoR so it looks a bit more plastic-like.

@@WillGibbons thank you very much for the reply!

It sounds like you may be using 'custom control' and don't have the settings optimized. If you try rendering max samples instead, it should match the appearance of the real-time view.

@@WillGibbons Thank you so much!!! Problem solved. You are the best!

Plug the texture into the cloudiness value in the material garph?

You can either set the color for the gem material as you wold with any mateiral, or increase the abbe value. 55 is typical for a diamond.

Yeah. Shouldn't be too hard :)

Will Gibbons thanks a lot Will!

Hmm. I'm not sure there should be a separate parameter for this. With cloudy plastic in KeyShot, the color of refracted light is determined by the transmission property. This is the color of light inside the material. This material type automatically refracts light due to its shape and thickness, so transmission value/color will determine the color of refracted light. KeyShot uses material models that are accurate rather than the typical Disney/BRDF model, which would give you parameters for every kind of light/property. You run the risk of creating a material that's not physically accurate going that route. If you want separated color due to refraction, I think you could use the advanced material or gem material which supports dispersion which is controlled by an abbe value. Sorry for the long answer, but I hope it makes sense.

@@WillGibbons Thank you very much. Your careful answer has benefited me a lot. Thank you!

Depends on what the effect is you're after. I usually use ranges between 70 and 100.

@@WillGibbons Thanks :)

Hi, thanks for letting me know. I am not sure what's happening as I have just clicked the link in the video and it's taken me to the right location: www.willgibbons.com/learn should work.

If you're looking to create scintillation, the answer is no, not in KeyShot.

@@WillGibbons 😢😢. That doesn't sounds good.

@@JCADHub Most people add this effect in post production. I do it in DaVinci Resolve.

Thanks so much for catching this. I've deprecated that URL and hadn't updated it. You can get the cheat sheet by clicking the link to the project files now!

@@WillGibbons Thanks Will!

I'd love to be able to help, but I'm not exactly sure what you mean.

KeyShot will not render materials with alpha, but you can render transparent materials.

Haha, last science class I took was in 9th grade, and trust me... I'm not doctorate material. Hopefully this video simplified matters.
