set TBBMALLOC_PROXY_ENABLE=0
didn't change the situation
happrentice works with or without it.
on the other hand my custom exe which is based on the Houdini engine API doesn't work with or without that definition.
I did found something that works, maybe it can help understand what's wrong:
“The custom exe must be placed in the Houdini installation directory which in my case is ”C:\Program Files\Side Effects Software\Houdini 16.0.557\bin"
copying the dll dependencies to a different directory near the exe won't work.
So, what I am doing is compiling the exe directly in that directory and the API seems to work fine now.
this is ok for experimenting but for automation the custom exe and the dependencies will need to be packaged, any additional ideas what could cause this issue?
thanks,
Emanuel

Can't open dophints.cmd
Houdini could not load (null)/python27/python27.dll
any idea what are the environment variable used by Houdini? maybe there is one not found for python which translates to null
Where I can find a sample .env file? cannot find any in the houdini installation path

I tried this:
C:\Program Files\Side Effects Software\Houdini 16.0.557\bin>hcmd.exe
Welcome to the Houdini 16.0.557 command line tools.
The Houdini environment has been initialized.
Starting command prompt…

© 2016 Microsoft Corporation. All rights reserved.
I am not familiar with Houdini and my background is software engineering, I am trying to use the engine programmatically to see if I can load Houdini assets and convert them into geometry used in a custom tool.
The error that I posted in my question, is something that gets printed out in the cmd if I try to write a simple program that initialize the engine and read a Houdini file. The error appears after calling Houdini initialization function: HAPI_Initialize.
if there is any thing specifically that I can run from the cmd to check what can cause the problem, I'll be happy to try out.
thank you!

Hello,
I am trying out Houdini Engine version 16.0.557.
I cannot pass the initialization phase, I get this error:
Can't open dophints.cmd
Houdini could not load (null)/python27/python27.dll
what is this error?
is there any python variable I should set?
where I can find a sample .env file that works with a very basic sample?
thanks,
Emanuel

Hi Edward,
thanks for the response.
…so in my case is not needed a plugin and It would be enough to use the Houdini engine API's from my app (focusing on Houdini engine API documentation)?
thanks,
Emanuel

Hello,
I am new to Houdini and I would like to check the possibility to integrate Houdini in our content generation pipeline. The experiment I would like to run is:
1. An artist create asset in Houdini (currently a simple digital asset that creates a sphere geometry and exposes a parameter for the radius)
2. In custom scene editor (c++ based app) a programmer should develop a way to expose a function to add a sphere in the scene with a given radius. This should demonstrate adding procedural assets in the scene using Houdini, with the understanding that in the future more complex assets can be used.
for step 1 Artist created helloWorld.hdanc, is this correct?
for step 2 Programmer needs to write a Houdini engine plugin for the custom c++ app? is there any representative sample that could be relevant to us?
HDK documentation, Houdini engine documentation, I am confused which one we should use and what these API's are called?
thanks,
Emanuel
