Here is an example of procedural lookdev in Houdini. We're not using any textures at all. And the purpose of this exercise is to develop our approach for creating complex materials. I'd encourage you guys to play around with it and come up with new ways of achieving certain look.

These types of discussions improve my creative and technical IQ. Thank you for the time investment and share. Looking forward to the next installment.

the critical thinking is essential. Getting to know how to approach things. Tweaking existing shaders is fun and all but tackling a difficult problem knowing exactly where too look is where is at. I really appreciate when people take the time to explain the road to get there. Thank you, subscribed.

This is mega good, even the quick slung together job looks great. I'm just trying to figure out how to fill the holes with water but still have the holes under it. Thanks for this

Great tut, ty. Trying recreate same effect with MTLX

Should be pretty straight forward as we're not using render engine specific nodes.

Awesome stuff, thank you! Would be nice if the potholes had water in them too.

You can layer water mtl based on the holes mask.

massive shader 😮 but looks great!

PERFECT So much to learn here, thank you very much. Would you suspect any obstacles if you changed to Karma XPU for this workflow?

Nodes might be different, not sure if MatX has exactly same ones, as last time i checked it was fairly limiting compared to native VEX nodes.

Hi :) thanks a lot for this tutorial, I followed along to the end and now I'm wondering how would I map this setup onto a winding road? (using a curve and a sweep node) Is that possible with this setup? I've managed to use 'rest' in both the SOP and vex shader, which seemed to work when using a bend node on the grid.. but wondering if its possible with curve and sweep? Thanks!

I found a solution, not sure if it's the best approach(?). I have 2 separate sweep nodes, 1 is for a winding road curve (the design I want), and the other is for a straight line in Z (like in your tutorial) that is the exact total length of the other curve, and the same number of points. In the straight 'line' node I use the expression 'arclen' in the length parameter and reference the winding road curve's length, and for the number of points I use the expression 'npoints' and again reference the other curve. I connected both into a 'rest' node afterwards, and combined with a 'restpos' node in the material- connecting it directly after 'P' from the surface globals.. then it works!

In case of a curving road I would recommend using a nurbs curve to drive the paint. Then in shader you will need to use minpos + distance and use global position and the position of a curve.

@@BizarreSelfProduction Thanks! I'll give this a go, and sorry- I've seen you've already answered this question before from another comment 👍

insane!! it will probably take forever to render rbd simulations with that shader...

@BizarreSelfProduction Жыл бұрын

well, as you've seen, it's pretty fast, no complex nodes are being used, so I doubt it'd be much slower than using several 4K (or even 8K) texture sets.
