Yes, I need full access of obj-exporting, due to material-exporting and separation reasons too, and embedding some additional information, like slash-enabled sub-object paths.

Ah OK I see cool.

Great to have this connection! Hope this will be further developed. I noticed a delay, when I am selecting the object to paint in Houdini. However, I am glad to have this plugin now!

Just got an error message when reimporting from 3dc:

Error running callback:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "opdef:/Object/coat_file_out?PythonModule", line 137, in getback
KeyError: ('',)

Great stuff. Thanks a lot. You've got an attentive and appreciative audience over here..

Under osx I get this error:


Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "opdef:/Object/coat_file_out?PythonModule", line 385, in go
IOError: (13, 'Permission denied', '\\Users\\Cordeiro\\3D-CoatV3\\Exchange\\import.txt')

Any ideia how to fix it ?
Thanks

This Applink only works on Windows because of the '/' being replaced by \\ (as I mentioned in a previous post)

You can easily fix it, edit the OTL, go to the Scripts page and at the very bottom of the code, put a hash (#) in front:

#fpath = fpath.replace('/','\\')

then it works fine

Andrew or BooBoo, I'm happy to fix this properly so it works on Windows or Mac/Linux. Works fine in H12 otherwise btw.

Actually, sending the textures back to Houdini is also broken... And Ptex is busted, 3dc exports .exr files instead of .ptex

Using 3.7.12 latest on Linux

Hi,

I'm trying out 3dc houdini applink the first time... and got stuck.

The handover from houdini to 3dc works for the geo but not for the textures. I checked the mtl-file via notepad: The two textures aren't generated in their desired location.
So I tried to put the original textures with the correct name into the folder, manually - problem persists, texture doesn't show up.

I tried with ptex paint, perpixel paint and microvertex paint. No luck at all to get the textures in 3dc...

Any hint?

Cheers

I dont use the applink tool at all, feel more comfortable with importing/exporting manually..

As for PTEX, its really easy to get it to work just create a surface shader node or modify a mantra surface shader node and drop in a Ptexture node and load in a .ptx file and it should be working correctly.

Also works great with displacement maps!

Hello. Is the applink between Houdini / 3D-Coat still not working correctly?
I tried it with the latest version of Houdini 12.1, couldn't get it to work. Hard to find good info too.

[subdproxy]

I like the 3D Coat Houdini App Link. It works great if I have nothing moving in my scene. Is there a way to turn off sending Geometry back to Houdini and just send the Texture maps? I noticed it removes all my Dynamic Functions (RBD) when re-importing into Houdini. The pivot seems to move on the object also. I like JohnnyCores idea of manually importing and exporting.

Hm, I use H12.1 and have the same problem - when I try to export -
Error running callback:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "opdef:/Object/coat_file_out?PythonModule", line 361, in go
AttributeError: 'SopNode' object has no attribute 'worldTransform'

no sources, no fixes

[sanchoflat]

poorly. I have some question, maybe now you - why houdini dont render NM as well. I try to change my mantra surface, but result is terrible. UV map is good. In 3d coat and maya render was fine, in houdini.....
