Yes, similar here. I have installed new versions from Houdini Launcher, but non of the newly installed version does open, or they do open for a split second, then close down without any warnings/error messages.
Did you figure out the reason for your crash?

Technical Discussion » Calculate light on a surface
- arhusvegard

Hi. Is it possible to calculate how much light is reflected on a surface?
I want to calculate Candela/cd and lux. I would guess this is possible since its possible to set relevant parameters from the light source and parameters on the material. But I don't know how to calculate this in Houdini.
I wanted to use Houdini to find out how much light is reflected of an aluminum surface and onto a solar panel.

Thank you so much! This seems to work fine
Is there a way to display the proxies? I found a tutorial by Atom from 2017covering rs proxies, he writes out bgeo.sc and proxies at the same time, and instance the bgeo for displaying the proxies.
Is that the only way to see the copied proxies?

Hi thanks for the help, this is very helpful! I have tried setting it up, But I had no luck getting in my geo. (I'm not good with coding, so might be I misunderstood the lines and comments you sent me?)
Im using Redshift.
Attached a snippet of the wrangle node
Cheers

HI, is it possible to instance multiple objects from disk. I have made 100 different models with a rop_geo. Then I have imported using a file node. I want to Instance all the different objects onto a grid of lets say 1000 points.
Today I have one geometry node for each object like below, so box, box1, box2 etc. But this is not optimized, and I would like to only use one geo node for importing the boxes. Can I write my code differently to import all the different boxes, then scatter them on my grid in my instance node?
My wrangle inside my instance nodethe code below is just an example for instancing 3 different boxes)
string instances;
push(instances, "/obj/Box");
push(instances, "/obj/Box2");
push(instances, "/obj/Box3");
s@instance = instances;
Here I have to manually make a geo node for each object I want to scatter around. But I will end up needing to make 100 geo nodes, that makes me a sad 3d artist
thanks for any advice on this

Technical Discussion » Cant select constraints on solid object?

I have installed the new H16.5. When i try to constraint points on a solid object, i cant select any points on my object i dop. I know its a polygon and tried different geos, but nothing. Is there a new way to select constraint points in 16.5? I have reinstalled my whole houdini, so might be some settings in my program. Have anyone had this problem before?
regards
SOLVED: i had to use a visibility node in sops to mark my tetras.

Hi. Im trying “fractured solid object” straight out of the shelftools, and when i take the model out of dops, and convert the tetas back to polyons, my model gets a pretty ugly result.
I have tried to dive into the solid conform sop, before my model goes into dops, but i could not figure out where to eighter make the triangles smaller, or to find som sort of an smoothing result.
attached image is the result after converting it back to polygons.
Anyone else had this problem before?

If I want to blow up a sphere like a balloon using fem or cloth, how should I proced?
Ive tried using a tranaform(scale it up)before rest position, but no luck there.
Thanks for any help

I have a baked agent and made a rbd ragdoll from it, and would like to throw it onto a FEM object(solid).
When in DOP it wont interact with my FEM solid object. Anyone know how i can make my solid object react to the collision of the RBD? (I throw my RBD object using velocity).
Let me know if i have not explained my self good enough.

Thanks for the reply! I wrote this before my morning coffe so i will try and describe better.
I just want to add “solid object” to my animated mesh.
I have my animated object, then add “solid object” from shelf tool, when i run simulation in dops, my mesh makes one tiny move, then falls to the ground, with no more movement.
I guess i have to use rest or Target from Sops into Dop, but i cant seem to figure it out.
I want my animated object to interact with DOPs.
example: a fatman with a big belly, want the body to bounce using FEM.

Hi. ive tried to figure out how to add FEM on a animated character from Mixamo, so that it can collide with floor and such.
Question: Is is a simple way to add FEM to animated object?
I tried to use organic object to it, but my animated geo just falls to the ground. I tried to have my animated geo before “rest possition” before into DOPs but with no luck.

Ive read a couple of threads here and on odforce forum, but i cant seem to find an easy solution on it.

Hi.
I want to emitt particles from a boiling geometry(geo with spheres, at a random lifetime). But i need to activate emitting just as my “boiling sphere” is at the end of its lifetime. Im using two popnets, but no sure if thats nessesary.
I cant to it with keyframes expressions it seems, because my boubles has random lifetimes.
Anyone know how to controll emmiting with expressions based on pscale or lifetime?
Let me know if i havent explained it good enough.
This is sort of an extension to the https://vimeo.com/152083535 [vimeo.com] tutorial on boiling geo.
thanks

I have a simulation where I emitt smoke from particles. I want my smoke to burst/explode for just a minimum of time right after my particles dissapear/die. Like boiling bubles or something like that. The smoke is now emitting as soon as the particle is born, i want it to emitt when when it dies.
Is there a good way to set up my smoke sim, so it starts from each particle in just at the end of my particles life and then make it explode?
thanks for any help

Ive made a human model in zbrush, exported it as an obj.file and added a skin material to it.
In zbrush i made a diffuse, normal and displacement map, these are included in the obj.
Im all new to Houdini, and having a hard time setting up my nodes in the VEX builder.
I managed to add my diffuse texture to the skin shader node. But when i try adding the Normal Map and displ. map, i cant get any result(at least a good one).
Is there a good tutorial out there? Been searhing for 3 days, but cant seem to find any good setup for human skin in houdini.
