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. 🌱

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

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.

#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.

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?

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! 😅

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
