Unfortunately my Crystal ball has stopped working.So post a simplified scene file and be as descriptive as possible with the issue at hand. As so far your post is anything but .

Rob

obviously noob enough to not understand this at first. Houdini's complicated eh?



I am attempting to use a tune I made to vibrate a plane with particles on it, firstly to see what happens, and secondly to develop further a music video.

It occured to me there should be an easy way to spread particles on the plane, then vibrate it, but I decided to create them out of a sphere, apply gravity, play the sim for a while then after some particles were spread on the plane, set this as their initial state, and start the vibrating from there.

I plugged the audio into the planes transform y (into a xform node) using a CHOPNET. Then made sphere emit particles, then made particles dynamic. I figure I had to disconnect the CHOPNET from the plane to allow the particles to settle onto the plane before settting their intial state.

Wondering if the fact it was a plane rather than a box (for some wierd reason?) was the problem I changed it to a box.

Then I encountered the problem above.

attaching scene file.

Thanks for any help you can give

No I didn't, but I just did and it still doesn't work

Dear Forumers,

Semi-noob here, almost pulling my hair out!!!

I have particles setup as dynamic objects.

I have a box as a static dynamic object.

I have gravity.

The thing I cannot understand is the particles fall and collide with the box fine……

UNLESS……

I use a transform node between the box node and the DOP import node (I want a flatter box).

Originally I changed the scale in the box node but then I remembered a tutorial telling me that dynamic objects can go weird if you do that rather than use a transform node.

Problem is neither seem to work….

WTF is going on?

Thanks,

5DN.

THANKS. V Excited to get to it. Swamped with work at the mo tho. This is going to be my own project.

What is the best way to do this?
Are there a range of methods?

Thanks,

5DN.

PS: This is for example controlling the translation of an object by the frequency of a sound wave, although I definitely going to experiment with more.

I was going to get these two to do Maximus with Maya:

Dell nVidia Tesla K20 Kepler 5Gb GDDR5 PCI-E GPU Computing Module 2496 CUDA Core


DELL nVidia QUADRO K2000 Kepler 2Gb GDDR5 PCI-E Card 384 CUDA Cores

Also good for Houdini?

Thanks for the help btw.

Well I have two machines already. My other is a relatively powerful laptop. Quad i7, 32GB RAM.

Also what is iirc?

Is OpenCL for simuations???

Dear Forumers,

I am about to come into a few thousand pounds and am going to buy the Apprentice Houdini and make the switch from damned cracks of Maya etc which are driving me up the wall!

I was looking to buy some powerful new hardware to beef up my system and am not sure what is good for Houdini.

I currently have a…

Asus Z9PE-D8 WS motherboard (which has 2 CPU slots)
1 Intel Xeon 10 Core 2.1Ghz
8GB of Kingston HyperX DDR3 1600 RAM
120GB SSD
1.5TB normal drive
Some super cheap Nvidia card

I wanna get another CPU and apparently it has to be exactly the same one so no problems there.

I was also gunna get another 7 sticks of the same RAM.

I guess my main question was what graphics card to get?
I understand Houdini can only support 1?
Will this speed up simulations if it is a TESLA for example?

Any advice from anyone much appreciated.

Cheers,

Nick.

is there one? that would explain it.

Dear Forumers,

Happy to join you here as a fresh Houdini fanatic.

I wondered if you could help me with an issue.

I done a voronoi fracture sequence and when trying to export fbx i ask it to export a frame range (the whole thing, about 600 frames) and it spits out only 212ish frames. Weird?

I got around it the long winded way (by doing three of so separate exports) but this is annoying.

Any ideas?
