This is meticulous and awesome! It is fantastic to gain insight to the incredible capability of Keyshot. Can't thank you enough for shedding light to all these crucial details.
Great and comprehensive explanation. Well explained too. I personally never go over 1.49 IOR since I try to depict the look of actual PMMA lens. But how you dialed in the whole scene was very meticulous. Love it!
Thanks! I fully understand that if working with a company that wants to keep things 100% physically accurate, you'll want to stick with proper IoR values. I just wanted to point out how much an impact that can have if you're chasing a certain aesthetic.
Awesome! My biggest nightmare is creating lights with realistic reflectors.....especially show them turned off. Most times I have to show some reflection of the led element inside the spot to highlight different lens options on the same spot.....My safest tip is to try and model the lens as close to reality as possible......And many times some of the lens surfaces have different finish to achieve the desired light output. Also very interesting idea to make the reflector a yellow color.... I always use polished aluminum and use warmer Kelvin (4000k in reality). That transparent glass tip for the main body is going to be a life saver from now on......Thanks.
Happy to help! Yes, I understand the challenges you face. Working with good geometry really is key here in this case. One thing that might help you out though is having an area light or white card (out of sight from the camera) that's being reflected in the reflector inside the lens assembly. This will prevent it from being too dark even with the LED/light source turned off.
Great tutorial. But I want to ask you something about the sample values that you use on final rendering. I usually set it around 150~180 to get the render done in about 4~5 hours (I have AMD 1920X CPU by the way) with lighting fixtures. But 4000 samples... isn't it too much (or too heavy for the machine to handle)? I mean, if it's the optimum amount to get rid of the firefly effects I understand but 4000 samples could take a lot of time I presume. So, could you explain a bit more about "selecting correct sample amount depending on a material" please?
Hmm, 4-5 hours for a single image to hit 150-180 samples on that CPU sounds really slow. I'd expect that to take no more than 5 minutes. I suspect something odd is happening. Are you using all the cores that CPU has to offer? What resolution are you rendering at? And is there a chance that NURBs rendering is enabled (if so, it'll slow things down substantially). In my case, I can typically reach 4,000 samples in CPU mode in around 20 minutes, though it will depend on several factors. The only thing you need to do is set up a region render on a noisy area and let it sit until it looks good and see how many samples it shows in the real-time view. That's the exact process I use to determine how many samples to render to, regardless of the material.
@@WillGibbons I took mostly street light renderings with PC lenses (partially frosted and partially clear plastic) and rough painted exterior and with emissive materials for LEDs... and you're right, I use NURBs due to the close-up images are looks better in my settings (by the way, i'm not consider myself as an expert on keyshot but relatively i do good enough renders -with no post work-) the real issue begins with the lenses mostly, unless i set 40~50 on global illum., i can't get enough quality on my renders. And again due to all of these, i had to set the sample value at least 130-ish when i take renders with mixed glossed lenses. also i should mention that below 50 samples it'll be definitely fireflies. my usual settings are (3000x3000px - 600dpi - PNG - All CPU Cores - 128 Samples - 1,5 pixel blur - 40 Global Illum. - Interior Mode with Caustics - model with NURBs) also I explode polysurfaces on Rhino to dissect and regroup-rejoin-layered up surfaces by the material that i want to use. then i import them into the keyshot. sorry for the long answer, frankly i didn't expect that quick response :)
Hey, sir. I love your keyshot videos, i have a several problems, like i dont know why when i render my interior with keyshot, the ceiling is so dark (actual paint is rough white), i don't know how to fix it. Please help me, thanks
Hi, sorry to hear that. I don't have enough information to help you out though. You can try sharing screenshots and asking for help in my discord server: discord.gg/3GJQn6NgX
hey can anyone tell why does my keyshot interior animation renders get shadow flickering issues even with 1000 samples applied? My main source of light in the scene is hdri pins.
I would need to see it to know why. It probably has to do with denoising (if you used it and it was turned up) or it could be due to caustics if you had them enabled.

Thanks. Sometimes, it's nice to do an in-depth tutorial.
Used it for another project and esp getting rid of the noise from the lights was an eye opener. Had my LED's way too bright! Thank you so much.
Excellent!

Good one! always something new to learn form your vids.
Great! Happy to hear.
Always learning something new. Thanks!
Glad to hear that, Alessandro! Thank you.

@@Dreamdimension7 Sure. In this discord server: discord.com/invite/3GJQn6NgXd
can you make video on jewellery rendering
I'm working on it. Not sure when I will publish it.

We are waiting.
Nice
