CG Sketchbook , notes and tutorials


Still Under Construction,  here i will gather link to all the resources i’ve shared with the community :


BlendFile download here :

-Note : v01 uploaded , contains a base diffuse+glossy shader preset i use for most materials , and v3 of the 3xStencil node.

Also contains an OSL script by BAO2 to create dirtmaps at rendertime , but it’s often better to pre-bake dirtmaps , using the baking script below


Python script for Blender download here :


Youtube channel for my tutorials:

  1. Thanks you for sharing your insights on texturing and using the node groups – I am trying to follow along, but I get behind with work 😀 I really enjoy how you explain the methods and reasoning when you make the tutorials

    Man, you’re fucking awesome!!! Keep working!
    Blender rocks!!!

  4. I really appreciate you sharing your stencil nodes here – I am trying to understand it better though so that I can add the group outputs for using the stencil parts to drive mix factors of other shaders besides just plugging the color to a diffuse. Getting there – but thank you again!

    • I have a working version here if you want to look

      • Hi thanks!
        Very interesting. So it’s basically using shader mix nodes instead of color mix nodes ? It can be much cleaner for material layout . IT’S probably Also slower to render, the general rule I found is to try and do the mixing of different maps as early as possible in the node tree to reduce duplicates and node count..
        Also I have a version with 1 input for the dirtmap and 3 in/outs for diff/spec/bump.. I’ll upload it asap, might be useful!

  5. Yes, I just tried to use your 3 part stencil to also ‘stencil’ the mix of different shaders based on the different image locations. I do appreciate that, I will definitely check it out!

      At frist,Thanks a lot for providing this,to all of you,its very helpful to me!

      I have a simpler way to do that what you want.
      No need to ungroup the nodegroups.
      directly,use R,G,B,the 3 colors ,input them to the 3 input socket respectively,and you got the result color。just add a“Separate RGB”node to separate it, it came to the three stencil ,can be able to mix different 3 shaders.

      • Glad it was useful, Thanks for the suggestion, i’ll try that !
