I've been trying in different ways and I always get Houdini to crash anything I want to make a QPushButton and show it, so, is clear I am doing it wrong

Would like to know how can we do pure C++ Qt interface and show it in Houdini, my tool at the moment, runs from a shelf tool and uses PySide to create the GUI, I want to just do all on C++

thanks

oooh damn, reading the docs again, seems like that is only for UE4 Material Instances, not for materials that come from Houdini, I'm I wrong?
could that be done? modify the Blend Mode for a material that comes from Houdini?

thanks

Hi
so I'm trying to modify the blend mode as described here http://sidefx.com/docs/unreal/_materials.html#MaterialsInstances [sidefx.com]

like this
To change the “Blend Mode” parameter from the default “Opaque” value, to “Additive”, add a unreal_material_parameter_blendmode detail attribute to your asset, and set its value to either “additive” (String attribute) or 3. (Float or Integer attribute).

but is not working, is this a bug? am I doing it wrong?

I'm creating a detail attribute as the note says and making it a string, there's no change in the created material un UE4



Using UE4 4.18.3 and Houdini FX 16.5.359

thank you

To solve that python issue I set Houdini to use the internal python version instead of Fedora version
like this in the houdini.env file

HOUDINI_USE_HFS_PYTHON=1

This are my results from that new Scene

the new block example Jeff added it's almost exactly the same as the stamp version, which is nice cause I like the stamp way, used to that and the new way is a little complex for new people.

So what's the magic ingredients that makes it faster?

this is on a 32 threads machine

Hi everybody
been testing and yes, the old copy stamping is faster then the compile

I'm using 2 Intel Xeon E5-2630 v3 Processors for a total of 32 threads, not latest gen but still good, or so I thought.

another user with a Intel i7-5930K Processor with 12 threads, is getting way faster speeds, like 10x

so not sure what to say, downgrade to one processor?

Yeah is for my Cycles ROP

looping the geometry is the slowest part not really writing to disk
that's what I want to make faster

right now having issues with matrix stuff damn camera doesn't match

Hi
I'm writing a renderer and exporting the geo to the format I need takes
the most time specially with geometry with millions of points of course

I think there was a post a while back about this, to process the geometry faster
can't find it

any tips?
use numpy maybe?
an external C++ parser maybe?

any tips are welcome

thanks

Hi
I know read the docs right, but I need a little help

well the parameters are not that documented, as far as I've seen, HDK Newbie here
so I'm just trying to figure it out by searching the samples, building and failing a lot

any reference would be great

or maybe there is and I just missed it.

Just a note, by parameters I mean, making the UI of an operator, camera selector, float and integer sliders, combo boxes etc, all that stuff that is really simple to do for HDAs.


thank you for your help

wow that is a long post

only thing I can say is I'm a freelance artist using Houdini and Only Houdini doing all sorts of jobs, all that with the Indie version, been doing that for 5 years now, so can it be done? yes I'm doing it right now
and I have so much work that I shouldn't be responding to forum posts

Cheers!!

final note: I have so much work because I use HOUDINI, that's why people come to me.

final note 2: I have a wife and a daughter so, is not like I'm a student living of this and 2 dogs
