  1. Hi all, First post on here on Odforce, hope someone can help me out. I've been using noises in the material network before to pipe them into parameters however; I got an unexpected result today. I've included a screenshot of the graph (just simple aaflownoise -> fit(noise,-0.5,0.5,0.25,0.35); -> roughness parameter) but got an extremely long and grainy render that was also a lot too light (the lightest frame I included). The other two frames are with roughness just set to 0.3 on the principled shader itself (The darker one has all other settings in the project exactly the same, the lighter one I bumped up the env light a bit). Feel like I'm missing something here. What's going on? Thanks in advance!
  2. Hello! I can't wrap my head around this one. I applied some random colors on the primitives with the default @Cd attribute & set the roughness to 0.1 on the principled shader. The colors show up and everything seems to work fine. BUT, just as a test, I tried to bind a custom roughness attribute with the same exact roughness values (0.1 on all primitives, just like it's set on the shader) and when I plug it in, the colors don't come through... I get a black & white render instead. I am lost as to why the shader/renderer is behaving this way... logically the outcome should be identical & I have no idea why the colors disappear. custom_shader_attribute.hipnc
  3. Hello friends, Today I watched Custom Shading in Game Trailers presentation from Sergio Caires (FMX 2018). The thing which really caught my eye was topic about anisotropic bump anti-aliasing (or specular anti-aliasing). This topic is presented at about 45:00 in the video. Please has anyone tried doing something like this? Do you have any hints how to do this kind of effect inside Houdini? I did not understand it good enough from the presentation, to implement it myself. Thanks for any kind of advice and have a nice day Link to the video:
