It has been a super busy week, but I managed to get back to my root-vine generator, optimize it a little bit more and adjust it so that I can use the Labs Tree Leaf Generator.

#Houdini tip

If you want to switch automatically based on what is input into a switch node, you can use something as simple as this expression - npoints(0)==0 - basically, this will switch to input 1 if the input 0 has no points.

The Scatter and Align node does something similar, but I believe my #VEX implementation handles it even better. The difference is that my implementation takes into account the size for each object I want to scatter.
Curious to hear your thoughts.

I spent some time improving the scattering tool in #Houdini, focusing on collision detection. Then I wondered, what if instead of detecting collisions, we generated points in a way that they don't intersect at all?

Thanks. I shared it on another post but here it is.

A brief snapshot of how it functions.

Creating a root system and implementing an offset mechanism to guide the root upward, avoiding intersections with the geometry. Initial steps.
Let me know if you would like to see the full setup.

Back to it. Tweaking the collision detection a bit more, using a threshold value to determine the level of overlap. Still need to run a few more tests to check if this is a good and efficient approach.

The #OSL shader called Complex Fresnel is incredibly useful, allowing you to obtain accurate values for various metals. I'm currently working with gold, and what you're seeing here reflects the physically accurate value. It's a fantastic starting point!

Working on some #procedural materials in #houdini with Arnold.
You do need a PHD to use the Layer RGBA node in Arnold. 😅

Had a thought in Houdini: what if you could convert the class attribute from a Connectivity node into letters? (0→A, 1→B, etc.)

Turns out a simple VEX snippet does the trick. It is a base-conversion from decimal to base-26. Not sure if it's the most efficient way, but hey, it works! 😅

Back to materials with #Substance Designer. I am trying to recreate Pietra Serena.

Made a little bit more progress on this scatter tool. Now, not only you can paint an attribute, or even better you can use splines to add and remove areas.

When scattering grass over large areas, one trick I like is to squash grass allowing it to cover more ground without more instances. #houdini #environmentart

Having fun with #VEX and #Houdini.

I was tired of @Substance3D Painter flagging nearly invisible UV overlaps on UDIM tiles.

So, I put together a VEX snippet to help with that.
Scale one or more UDIMs

It handles complex geometry beautifully (tested on 20 M+ poly meshes).

Grab it from my GitHub:

I had a bit more time to work on the damage tool. After addressing the edge damage, it is now time to incorporate surface damage. Trying to be as procedural as possible, but also keeping in mind efficiency.

Working on some optimization. Going from 32 to 5 seconds. This was a test looping through 60 assets. And yes, I know Labs Edge Damage does something similar but this is the basis for a more complex tool.

Some #wip for a tool I am developing in #Houdini to add edge and surface damage. The primary objective is to perform an initial sculpting pass, typically done something like ZBrush.

I’m incredibly proud to finally share "The Screaming of the Tyrannosaurus," our latest episode for Netflix's Love, Death & Robots. This project holds a special place as it was the final piece from the incredibly talented team at Axis Studios before the studio sadly closed its doors.
