b°wide NodePack – for Blender

b°wide NodePack – NodeGroups for Blender Cycles and Compositor

b-wide_NodePack_cyclesb-wide_NodePack_compositor

Here is my hand picked selection of NodeGroups i’ve created over the past 2-3 years.  There’s everything, from simple little Tools, Materials, UberShaders to Compositing. Some are made quickly, on some i spent countless hours.

With this first release i’ve put together some information about every NodeGroup. Not too much, but mainly what the NodeGroup is supposed to do. I think it’s important to get a quick start on them, cause really, some of them might seem confusing (even for me😉 by just looking at it.

I’ve taken quite some time to re-check everything, set usable and good defaults and to make them as easy as possible.

All of those NodeGroups are made by me, with the exception of the CondFresnel in the Metal-Kn.

I always try to not let them break energy conservation – so they should be safe to use in any circumstances.

My future plan is to pick some of them and explain in detail what they are doing. And this is where i need your support. Since this all takes a lot of work, and there are so many NodeGroups to choose from, i need you to tell me, about which NodeGroup/s you want to know more, please leave a comment bellow.

I honestly hope you enjoy them, learn from them, use them and show us the results here. If you have ideas for further NodeGroups or any questions, please let me know.

Lastly, it really takes a lot of time doing this, so if you find them useful please consider a donation.

  1. Bashi… this could be the most useful thing I’ve used in a long time! Thank you for making this available… I’m looking forward to trying it out.

    My only recommendation, is to make images of your screenshots of the node setups higher rez, when I first saw this on Blender Nation it was hard to read all the stuff you had in there.

    But again, thanks for doing this and it will surely be useful to many people

  2. This is amazing. Many thanks for that. My dream would be to have a website to exchange and explain nodegroups. Would be nice. Many thanks again, this is a great think what you did there!

  3. I need help with using the PassCombineDenoiser. I am putting all the inputs in except for transmission, for I have no transparent materials. And, as suggested, I am rendering normals and putting Firefly noise reduction on my indirect renders. My final composite renders out as a glitched out image of black and white stripes with a grayscale silhouette of my model. Is it because I am connecting the AO, Environment, and Emission from the render layers into the PassCombineDeNoiser when I have no AO, environment, or emission? Or is it because I should have a few mix shaders before connecting RenderLayers to PassCombineDeNoiser? I am in Cycles, running Blender 2.69, on Windows 8.1. Please help anyone

    • If you don’t have a specific pass, just don’t connect it to pass combiner. Otherwise, can you upload your .blend (or a simplified version) to pasteall or mail it to me, so i can take a look at it?

    • blender has some issues with the blur nodes – the only way i found to fix this is to add a Mix node with activated Clamp before the blur nodes, in this case before you plug them into PassCombineDeNoiser.

  4. I have a blender 2.69 the latest version. I tried to load it but it doesn’t ! even I tried to open a startup.blend but it gives error ” file format is not supported in file……” Am i doing anything wrong?

    • Let me guess, you have a new mac and/or osx 10.9? This seems to be a issue with that, i will report it as a bug as soon as i know more. Have to figure out first what it causes, just got my new mac and the same “problem” as you.

      • Can anyone help with this so it works for a Mac user of blender? I got excited when I learned about your nodes, but they won’t open for me. I’ve tried a few back versions, going back to 2.68, on my Mac.

      • Somehow it happens that in certain Situations the File Extension .txt is added to this File. Just delete .txt or rename with .blend extension. Osx asks: Are you sure you want to change the extension from “.txt” to “.blend”? then click Use.blend

  5. Wow. Thanks a lot Bashi, this is very AWESOME and highly useful! Well worth the donation.

  6. Amazing set of nodes. I have just discovered them and I am willing to test them “asap” hehe. Thank you so much Bashi for sharing this great work.

    But, I have a question may be you can answer me: Is there any way in Blender to use a set of procedural textures nodes to drive the distribution, scale, etc of particles? I´m trying to have a set of nodes to create a procedural texture and at the same time to use them as a texture on the material, those to put particles in some places determined by the texture, but maybe it is not possible.

    Thanks a lot again

    • Hi Jose. It is partially possible. There are Textures Particles can use, but not Cycles compatible… You could Bake them and use Image Textures to drive Particles.. So, it is possible but not too straight forward..

  7. Downloaded these and use them on a regular basis.They work really well.Still don’t know how to use all of them,but sure like the ones I have tried.
