    Very well explained. The adjustment is also a step toward industrial standards, as every as render has this kind of shaders, making it easier in the future to switch shaders. Also the UI change and remembers more to what Redshift and Octane looks like in Blender. There is a lot more that need to happen in Blender, like Layer, Hierarchies, Groups etc.. but it shows that the took care about the main critics

    i think that to show the significance of the energy conservation, you should do a white furnace test as it shows pretty clearly that energy conservation is broken (the silhouette being brighter than the env light). showing it in effect on regular scenes doesn't really show how important energy conservation is because it just simply looked like things become darker

    • @christopher3d475
      @christopher3d475  Рік тому

      I did an entire video on the energy conservation problems in 3.X. But I should link to it in the description. ua-cam.com/video/kgORQ5tMe2I/v-deo.html But you're correct, the furnace test would be a good example.

    Thank you so much for your lectures, it’s really helped me. Thank you again. Please, do you have any videos on how to make photorealistic glass in blender? I’m not too satisfied with the glass in blender. Or Do you have tricks or tips to get photorealistic glass?
    Hope to hear from you soon, thank you.

    • @christopher3d475
      @christopher3d475  Рік тому

      Yeah, glass is an area that I think could use some improvement, and in fact there is something on the to-do list called nested dialectrics that I'm hoping makes it into a 4.x release.

    You briefly me that part of the new BSDF is using volumetric scattering. Could you expand on that a little?

    • @christopher3d475
      @christopher3d475  Рік тому

      Yes, I should have elaborated on this. The algorithm simulates actual thickness for the coat layer, and if you use a tint, the degree of that tint is influence by how long the rays travel through this simulated thickness. The longer the rays travel (say at high glancing angle toward the camera), the more absorption happens and the stronger the tint effect is. It's an elegant way of applying a tint because it's following physical principles.

  • @pheeeshy
    @pheeeshy Рік тому

    Absolutely love it

  • @gottagowork
    @gottagowork Рік тому

    The glass coating looked like something that would be better simulated using volume absorption. Dunno, just felt like a weird example. Maybe it would be better to show a more natural application of coated glass, like anti reflective coating on eye glasses that tend to cause that green tint on facing angles? Yeah I know those are "optical coatings" and not necessarily reflecting what a rendered coat is supposed to do, but still.
    Did you check if substrate IOR is automatically lowered for a dielectric when a coating is applied? I know there was some talk about Blender supporting "nested IORs" a while back, but I'm not sure if at least Principled was affected or the implementation was abandoned completely. Only dielectrics though, doesn't happen to metals whose (unsupported complex) "IORs" are very high anyway. Ex; bubble wrap lowered into water loose pretty much all reflectivity, whereas a metal spoon does not.

    • @christopher3d475
      @christopher3d475  Рік тому

      The glass example was just to show that it affected components sitting below coating. And nested dialectrics isn't implemented yet, it's slated for a post-4.0 release. I would assume when that does get engineered they would apply it to a glass with a coating for the correct IOR configuration.

    I find myself not missing any of the videos you're releasing lately. I appreciate the deep understanding you have about this topics. I was looking around in your channel page and couldn't help but notice that your contact information has an Apple owned domain in it. Is this something you are allowed to talk about? I've always seen Apple as a great reference of what clean and professional renders should look like. Funnily, this is the same reason that made me like your content, clean and professional. I will definitely be waiting for more!

    It's not directly related to this video, however could you recommend me a way to do post production of AgX still images? I use Photoshop and Affinity Photo mainly, but neither of them imports te AgX correctly. I could do grading in blender natively, but blender's image viewer is trash and I also don't like the compositor UI/tools provided. I am seriously considering to learn DaVinci Resolve for grading, but for now I am stuck with simply exporting whatever comes out of blender and work with that in PS.

    Commented this in the last iteration but Idk if you saw it so I will comment it again.
    Would you be willing to do a video on physically accurate iridescent insect shell materials like that of a beetle? This video reminded me of that. And most people achieve this effect by plugging a layer weight node into a colour ramp node. However I feel like that isn't gonna have accurate results. I'd love to see what would be a more physically accurate technique.

    • @christopher3d475
      @christopher3d475  Рік тому

      What you're describing sounds like iridescence. This is a feature that was actually functioning in an early development build about a year ago in the then 'Principled V2'. I'm pretty sure it's planned for a follow up release to 4.0. It should be able to do what you're describing.
