Check to see what your HOUDINI_TEMP_DIR is set to, and make sure that it's pointing to a valid folder.
I'm not sure if it was set in the first place, so I set the variables in the Windows Environment Variables, and now it works!
BTW, I tried setting the HOUDINI_TEMP_DIR in my houdini.env, but it does not seem to be recognized by the Houdini Engine.

I added the following line:

HOUDINI_TEMP_DIR = "%USERPROFILE%/AppData/Local/Temp/Houdini_temp"

Are you not able to set the variable in the .env?

So here is what I get.
getenv("TMPDIR");
// Result: C:/Users/echigo/AppData/Local/Temp //

string $hipFile = `houdiniEngine -makeTempDir`;
$hipFile += "/houdiniEngineForMaya_" + `getpid` + ".hip";
$hipFile = toNativePath($hipFile);
// Error: Error creating temporary directory: \houdini_temp //
// Result: \houdini_temp\houdiniEngineForMaya_23816.hip //

Houdini Engine for Maya » Auto load V-Ray and Houdini Engine

Hi,

When I Auto load V-Ray(3.60.03) and Houdini Engine(3.0)in the Plug-in Manager in Maya 2018, the next time I reload Maya, V-Ray gets unloaded and I cannot load it through the Plug-in Manager. It will not allow me to check the “Loaded” box.

If I go into my pluginPrefs.mel, and load Houdini Engine after V-Ray, then it will load correctly. (see attached)
But upon exiting Maya, I believe that Maya automatically changes the order to where Houdini Engine will be higher on the list of commands, thus loading before v-ray.

Anybody have any similar problems?

Are the above scripts MEL? If they are, here are my results:

houdiniEngine -makeTempDir;
// Error: Error creating temporary directory: \houdini_temp //
// Result: \houdini_temp //

——————————————————————
string $hipFile = `houdiniEngine -makeTempDir`;
$hipFile += “/houdiniEngineForMaya_” + `getpid` + “.hip”;
$hipFile = toNativePath($hipFile);
// Error: $hipFile += “/houdiniEngineForMaya_” + `getpid` + “.hip”;
//
// Error: Line 2.13: Syntax error //
——————————————————————
getenv(“TMPDIR”);
// Error: getenv(“TMPDIR”); //
// Error: Line 1.8: Syntax error //
——————————————————————
When I ran the below command, it seemed like it went through, but I dont know if/where the HIP file was saved.
houdiniEngine -saveHIP $hipFile;

Installed Maya 2018 Gold, but still cannot use the debug feature. It crashes the same way as it did before. On the upside, atleast the volume is being produced now.

Hi,

I recently started using Houdini Engine for Maya and was wondering which versions of Houdini Engine are compatible with which versions of Maya. My company uses Houdini Engine for Maya 3.0, due to not wanting to upgrade Houdini FX(Currently using Houdini 16.0.1154). I am able to use it fine thus far in Maya 2017(Update 4), but when I use it in Maya 2018(Update 5), it seems buggy. Volumes do not show up and I cannot use the debugging feature(View Assets in Houdini). I receive the following error (// Error: Error creating temporary directory: \houdini_temp // ) and when it opens Houdini, I get another error (see attachment).

——————
Windows 7 Professional 64bit
Houdini 16.0.1154
Houdini Engine 3.0
Maya 2018 Update 5
——————
Any help would be appreciated. Thank you in advance.

Naoki

Houdini Engine for Unity » Fluid vertex animation flickering

Hi Mike,

I think I got it to work. On the Houdini side, I rendered out the position and normal maps as .tga, instead of .exr.
Then, on the Unity side, in the texture import settings, I had to adjust the Max Size depending on the size of the rendered out maps.

I rendered out using Target Texture Size of 2048, which resulted in a 2048 x 2987 image. The default Max Size for a texture in Unity is 2048. Using the default settings, Unity relatively scaled the image down. In this case, 1404 x 2048. I changed the Max Size to 4096, which kept the original resolution and everything looks good.

Thx for all of your help.

I checked my settings and everything looks like its in order.(see attached image)
I also exported out a low res sim and adjusted the Target Polycount accordingly, which resulted in the same pinching as before.

I then exported out the low res sim with the Game Dev Toolset for H16, which gave me decent results, shapewise, but I get that flickering still.

I've uploaded all related data to the link below. Would greatly appreciate it if you can check it out for me. No rush though.

Hi Mike,

Thx for the quick reply. I tried using the latest version of the GameDev Toolset, but I still get the flickering triangles if my Target Poly count is too high. I lowered to 15000 and I get the mesh to preview in Unity, but the Global position is wrong as well as some pinching going on (refer to attached image). I'm thinking this has to do with the color conversion of the texture maybe? By the way, is the Target Poly count referring to the polygon count or the point count?

Hi Mike,

I'm working in Houdini 16 (my company doesn't want to upgrade to 16.5) and I am getting the same flickering when exporting a flip sim as well. If I export a low poly sim, I can get decent results in Unity, but is there any work around with the Houdini 16 Game Dev Toolkit so I can get some higher resolution simulations to export?

I have Houdini 16.5 Apprentice, but with the resolution limits, I cannot export the textures out. I dug into the fluid COPNET and found that there is a Gamma node and Convert node attached for exporting to mobile(Unity). If you dont mind, can you give me any tips on what else I would need to change?

Thx in advance.

Hi. Can anyone give me any tips on how I would go about seamlessly looping particles.
I tried using Peter Quint's method on looping flames [vimeo.com], but apparently that method doesn't work with particles.

I've attached a hipfile with my failed attempt. Any help would be greatly apprecreciated. Thx!
