On the same topic of this root system, nothing is perfect, so at times I end up with splines intersecting the geo. Using a VDB to determine the inside\outside surface, I can manually set the distance or automatically average the P based on nearby points. Let me know if you would like to check this

Solved the root intersection problem! My workflow now takes into account the radius/pscale for each point and gently pushes overlapping points away. Clean geometry, no more intersections. 🌱

#VEX #Houdini #procedural

Currently working on my root tool, and for the main branch, I want to add some secondary branches on top. This setup allows me to adjust the number of roots, individual scale and offset. Next is to detangle the intersections. I'm aware of the detangle node, but it isn't giving me the results I need

New update

Branches now look way more natural since the older ones are bigger than the smaller ones closer to the tip. This style of growth is known as acropetal development, and it really improves the overall look.

Sometimes knowing VEX makes you blind to simpler solutions 👀
Needed to select all the geo without UVs. Almost reached for VEX... then realised I could do it with just TWO nodes. This is your reminder: the 'best' solution isn't always the most complex one.

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.

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?

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.

Adding some control for dirt and leaks

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.

#3d #texturing #wip #MadeWithSubstance

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

First steps for a scattering tool. #houdini

Having fun with #VEX and #Houdini.
