PBR Shaders updated to version 3

Hi Guys,

Just put out another update for my PBR shaders. A few tweaks were made to all of the shaders but the major change was in the metallic shader where I incorporated the complete redesign that I recently used in my Substance Painter shader on BlenderMarket. Should produce some really nice metal results.

As always feedback is appreciated. Enjoy!

    Hi,

    First, I really want to thank you for sharing your groups: I rely on them on a regular basis.
    One thing I couldn’t understand so far is the glass render settings: it always looks dark/black.

    I wonder if you have any suggestions as to which render settings I should tweak to get a proper result.

    I’m not sure this is the right place to start such discussion: if it’s not, please forgive me.

    Still, I really thank you for this tremendous tool set!

    Cheers,
    Nicolas

      Hi there,

      It’s a common issue with glass in cycles. I’ve included a fix in the shader that should help. The shadowfix slider makes cycles treat shadow rays differently, basically using a transparent shader in place of the glass. This should help a lot in theory. Beyond that I’d make sure you have plenty of transparent bounces in the render settings.

      I will be readdressing glass in the next update to see if some improvements can be made.

      Hope this helps and thankyou for your kind words and for watching.

    Thanks for you r quick answer!

    I’m debugging my last project trying not to eliminate some mistakes the client didn’t notice (I couldn’t set up a proper glass material and ended up mixing glass with transparent shaders).

    Still I took some time to check my model: normals were pointing in the wrong direction…
    I hoped flipping the normals + your new package would make things better but no… Still black even with the shadow fix slider all the way to 1.

    What would be a high number of bounces for you?

    Thanks a lot for your time!

      Tell you what, lets make this easier. Please contact me via the contact form on the site and I’ll arrange for you to send me over the .blend to take a look at. Hopefully I’ll be able to figure the issue out.

    Hello. Thank you for your fantastic work in creating your PBR Shaders and your Substance-to-Blender add ons; I use both and have donated to you and would encourage everyone who uses these add ons to also donate to you.

    Question: I am storing your add ons in my startup .Blend file. With each update, I notice that the OLDER versions of your add ons remain within the .blend file. For instance, after appending the latest version 3 of your PBR shaders, when I use SHIFT+A to add the components into the Node Editor, a list comes up with version 3, but also still listing version 2 and version 1. How do I delete the older versions from the .blend file?

    Thank you!

      Hi there Michael, thanks for the kind words. I’m always thrilled to hear people are making good use of my tools and tutorials.
      As for your question, to remove nodeGroups/materials and pretty much anything else from your startup file you need to delete the associated data. The way to do that would be to bring the item, in this example, lets say the v2 PBR into a material. Then delete it using ‘shift’ when you click on the little ‘x’. Also ensure the ‘F’ isn’t marked. This will tell Blender you want to permanently remnove it. Do that with all the things you want gone, then re-save the startup file, then start a new scene and they should all be gone. Hope that helps.

    Hey BlenderBrit,
    thanks for you good work all the time. It´s helped me a lot to improve my work.
    On small think would be great. Maybe leave a short discription about the PBR Shader
    in the blend file. What means the Odeg Adjust or the velvet sigma?
    Thanks an have a nice day:

      Hi there, thanks for the nice comments. Those features are explained in the original usage video on my youTube channel. I hope that helps and thanks for watching.

    Hi, just a quick one to tell you I solved my black reflections issue with your glass shader. As suspected, it had nothing to do with your shader: clamp indirect (Properties/Render/Sampling) was set to 0.03. As soon as I set it back to 0 or at least 1, the reflections are back to clear.
    Everything is clearly documented on this link (http://blender.stackexchange.com/questions/64053/glossy-with-0-roughness-gives-dark-reflections/64148#64148).
    I thought it could help somebody.
    You certainly help me a lot with by sharing your precious knowledge!
    Thank you very much!
