KeyShot Quick Tip - Volumetric Lighting: Creating Light Rays

[@anvekarakash]

great video

[@张志杰-v2z]

The rendering speed of the case in the author's video is very fast. I would like to ask the author what is the computer configuration. My computer is too low-level and the rendering speed is too slow.

thanks ❤❤❤❤❤❤❤❤❤❤

No problem! Glad the tutorial was helpful.

I have a strong rendering machine with 48 cores but an older graphics card. Test it seems like that and it takes a couple of hours do I have a look great. When GPU prices are getting to normal I might have to upgrade to an NVIDIA RTX6000. Or do you have any other recommendations?

[@keyshot]

The RTX6000 is a fantastic card to work with, however, most powerful professional cards should significantly speed up your render times.

Hi, there is one thing THAT i see in every other renderers on each new release version. That's speed improve. They always code new sampler method or optimize current sample method. But I never see that in Keyshot. Specially at CPU. Why ???. Thanks.

As a new member of the KEYSHOT family I find this demonstration brilliant, but I do wonder, how do you convert your png or jpeg to .ksp? Thanks

[@keyshot]

Hi @Samuel H-S! To export a .ksp from KeyShot, you would need to select the "Save Package" option from the file menu dropdown. From there you'll be able to save your scene as a .ksp to any folder you like. Hope that helps!

Nice

[@philbunch6221]

How about adding a link to the KSP file for users to download? The link on the Blog does not seem to work. Also, may want to caution users that the render time may be significant. Getting the scene close but not perfect in the realtime view, then letting the render spin overnight or at least a couple of hours is a good way to improve the results if you don't have access to a super speedy machine.

[@fatih2313]

When you press the render button after sitting in real-time view for some time, does Keyshot continue rendering from that point? Or does it start over?

[@muhaY-vb5vp]

does the gods ray just come out from point light or it can come out from emmisive material?

[@keyshot]

To create god rays you need to use a physical light, emissive lights don't produce enough projected light to create the effect. The best results for defined rays come from using spotlights or IES lights specifically. Hope that helps!

[@karltroidvsbondman]

Why it is avaliable just for spotlight? :(

[@keyshot]

A haze effect is possible with any physical light using scattering medium . However, if your goal is to create a visible light beam, you need to use a directional light to create the effect.

its good but looks flat
