Re: Orange juice tutorial

Volme setup makes sense for me. But altering shadow color, naaah.. not too sure about that one. there is no way around this. Most engines assume transparent shadows for glass/transimtant materials otherwise you would have to calculate full caustics. For example cycles does automatically compute sha...

Re: Spectral rendering

One way of comparative study is you give both samples to X number of people asking them which one they favor more, then do the stats. The other is unbiased, scientific way of using specialized image analysis tools and color science to describe the methods, techniques, do the work, get results with ...

Re: Spectral rendering

Here's latest Octane for Blender: Download Octane 2019 for Blender 2.81 RC (free tier) - Updated 2019-11-12 Yes but how do you compare octane vs spectral rendering octane? Is there a switch to turn of spectral rendering in octane? This new build of cycles allows for pretty much direct head to head ...

Re: CGI tech news box

:idea: DECALMachine w/ Shrink wrap modifier . that's way too much effort compared to a texture vs texture. He is turning bitmap into paralax map with near the same quality as displacement at near the same computational cost of bump mapping... Have you used any - either Max+Fstorm or DECALmachine? I...

Re: Spectral rendering

Btw Radeon prorender is doing spectral rendering on viewport with vulkan : http://www.cgchannel.com/2019/12/radeon-prorender-for-blender-gets-full-spectrum-rendering/ I think they are using the word "spectrum" with the meaning "a wide range of techniques" here, since they are talking about a transi...

Re: Spectral rendering

Also Dade, you said dispersion is pointless for pathtracers but how do you do diamonds, and some thin film dispersion effects.. All spectral renderers can do those effects, yes they might not be able to do caustics but rest looks correct and there is no easy "fake" to do dispersion. There are some ...

Re: Spectral rendering

The big problem that made me think there is more to spectral rendering than fancy effects is how those saturated colors interact.

Re: Spectral rendering

Look like it is possible to convert RGB to a kind of fake spectral without affecting performance : https://radiance-online.org:447/radiance-workshop1/cd/Ward/PicturePerfect.pdf well, as the quote from dade says. It's not making rendering slower but generates more noise. Now, while I'm always lookin...
