hi there,

I can't seem to get objects to show up in the Houdini view after loading.

I tried spacebar H and still nothing,and these are objects known to load just fine in say, meshmixer.

I can get click on torus, cube ,etc. and they show up just fine after I click to place, but that's about it.

P.s.–MMB on node shows all 1.35mil tris are there, so the obj is there, so why isn't it visible in the viewport ? 0-0

ty

Try spacebar G. (it will change view to fit geometry selected)

When you middle click, check the x,y,z size. Houdini's default is 1 unit = 1 meter so your model may either be really small or really big.

I have no idea how I got this working ,as while I'm sure the model is 1.3 mil tris and is 1sq mil wide & high, doing spacebar G still isn't bringing anything into view,and it works fine in meshmixer and blender.

Yes I'm new to Houdini, but it shouldn't be this hard to import things right

If your model is really big (or small) you may also need to adjust the clipping distance for the viewport camera. (press D with mouse in viewport or adjust in camera settings)

You can also try scaling it down by setting the Uniform Scale parameter on the object to 0.001 or similar value, or use a Transform SOP to do the same to the geometry itself.

I just set it to auto, does that work well enough?
I also tried setting manually (right field) to 10000 but still nothing.

I tried .0001 but I still couldn't find it,and their seems to be ( MMB node) 2 children SOP's.

I'm out of ideas and wasting time I need to spend elsewhere.

Anymore ideas feel free,but I must move on for now.

ty for trying but given mesh loads elsewhere its time to move on.

“1sq mil wide & high”
if it's that big in blender then it will be 100 sq miles in Houdini
scale it way down in SOPs and try viewing it in an orthographic view…

but this begs the question - what are you planning to do with it in Houdini?

I get this in Houdini:

ANOMALY: meaningless REX prefix used
ANOMALY: meaningless REX prefix used
ANOMALY: meaningless REX prefix used


Whats causing that, and is it relevant ?

Why would loading it in Houdini increase its size so much , and if so what reason is Houdini structured this way (or are other apps that far off ) ?

Once the OBJ loads,there is a widget in center of screen, with red ‘balls’ on six sides, is that normal ?

I try to ‘scale’ it with scale button on left side of UI, and while the widgets do grow outwards, it has no effect, so I tried as you suggested, to scale it DOWN, and got this as Houdini crashed:

Any ideas ?

Btw I plan on working on this object in Houdini, in various ways , and deciding IF Houdini has anything specifically to offer me for this mesh.

ty

Also, what is this SOP I keep hearing about. I"ve watched a few tuts and its never brought up.

However, other than scaling via text inputs in property panel (right side top ) or icons far left top, how is this done ?

If via node, I see no way to scale anything after pressing tab, so it seems I'm overlooking it, but I did try.

thx

I could still use help with this, where is SOP ?

I've seen no info on it in tutorials, and no one has responded to the error output I sent.

thx

could you upload the mesh here?
or contact support@sidefx.com and upload it (in NDAs are applicable)?

I'd be more than happy to have a look and see what the issue is.

TO so much for responding, I would have sent this before now,but I was on the ‘other’ forum not knowing about this new one, hence

I ‘ll alter it to protect my licensing and go from there.

Sorry to have to be secretive, but that’s where things are atm.

TY so much for reply, I'll get right on it.

Cheers

Ok weird, I got it that time.

Imported PLY, haven't tried obj, but at least its there

Saw it immediately, then spacebar G.

NO idea what was going wrong before, but we're here (

ty!

Sadly back here again it seems.

I“m unable to load most obj's files short of one and I have no idea why.

Is there a triangle limit in apprenitce ? I didn't see that mentioned in the notes for this version of houdini.

It just makes no sense.

Is there something I”m missing that needs to be done in houdini after loading a obj ?

Having a hard time finding a tut for just that, mostly its starting new objects or ‘test’ meshs, all which load fine.

ty anyway this is agrivating and time consuming when I shoudl be doing other things like game development

did you ever send an example to support@sidefx.com?

what application is making these obj files?
can you export to another format?
what operating system/hardware are you using?

I can't send to anyone atm :

“ Sorry to have to be secretive, but that’s where things are atm. ”

Please respect that, and I shouldn't need to send any data at all, these OBJ's load in blender, cinema 4d and meshmixer. It makes zero sense houdini can't load them, they are fairly simple meshes considering its only 1.3 mil tri and meshes can typically be 10 times or more that size. Clean meshs I've made sure of it. NOt 100% quad, but clean.

Created in meshmixer, exported to obj format if that helps any.

I can try PLY, but I“m also having trouble with PLY files now though I mentioned earlier I could load one, I guess I got lucky.

Windows 10 64 bit, amd motherboard 3 yrs old, ssd , 8 gb ram, HD 7750 2gb gpu.

I tried everything before needing to ask for assistance and and looked at several houdini tuts on youtube and elsewhere , no no authors seem to be loading files just my luck ( hoping it was something odd I was doing wrong, being new to Houdini).

IF the obj's weren't working in a autodesk app, I wouldn't be asking for help as I would assume its on my end, but I trust autodesk software is written acceptably, hence my seeking aid.

ty so much for undestanding.

PS- I just t ried to run houdini appr. first time this am, and its asking for license, is that a known issue or more likely a windows 10 anomaly.

I also get a error message after loading houdini, something about REX ( in a windows , far right bottom ) saying this:

” ANOMALY: meaningless REX prefix used "

Is this causing houdini to struggle loading some mesh objects ?

Maybe instead of the file that you need to keep “secret” you could make a duplicate that is about the same size but with a different objects/s ( content ).

That way if you are having the same problems as the original you can upload it here and one of us can have a look and maybe be able to help you out further.

Houdini is very much an “open ended” type of software meaning you can do the same thing a number of ways.

Depending on settings and how you do it might not cause any problems one way, but many problems another.

Which is why it is very helpfull to be able to upload a file and someone else look at it through another install of Houdini.

can you use meshmixer to make an example that is smaller and also having nothing to do with your current project - and try that, and upload it if it doesn't work?
I don't think we have meshmixer installed anywhere…I'll see if we can do a test on our end.

That makes no sense. Different object/con

ty for your comment, but its not just one obj or ply I'm having trouble with its at least 10.

I did try a very small mesh, all quads that Igot from blendswap and it loaded fine , which makes me wonder if houdini apprentice possibly can't handle a mesh that is too large or has triangles in certain arrangements ??

I'll try and alter the mesh keeping its size and see if it still refuses to load, yet loads in meshmixer and send that to the email noted on this page.

Yes, I just typed to first responder, and I will do just that, see if it stil won't load yet load in MM.

Just got home and I did think of that honestly, just never got around to it.
