Hello
Several posts, speaks about “toon render” / “celshading” in Houdini, but it seems there is not easy solution to get this kind of render in Houdini.
Does anyone tried to get this effect, for an houdini scene, in a third party renderer ?
Thanks in advance for any help/informations.

Hi,
1) Houdini's vector renderer is WREN. See:
http://www.sidefx.com/docs/houdini10.0/nodes/out/wren [sidefx.com]
As far as I remember you can get the most flexible effects by compositing together the WREN and MANTRA outputs.
2) You can achieve some nice toon-like shading using the “ramp” material, in the material gallery - no need to write your own shader, simply adjust the color ramp to generate more flat, toon-like shading.
Hope that helps,
Greg

I tried the ramp material
I removed opacity
I add two color point
I place Point 2 and 3 very close
I set point 1 and 2 to “red”,
I set point 3 and 4 to “dark red”
Then I get a cellshading render (only the color, not the line).
Concerning WREN and mantra, I'm looking for a tutorial (because I don't really understand). If anyone have any advice for a tutorial allowing me to understand those two, thanks. After learning both of these I suppose I'll be able to create a celshading effect.
Thanks

There is some info in the notes for this gallery item:
http://www.sidefx.com/index.php?option=com_content&task=view&id=1225&Itemid=279 [sidefx.com]
It uses Wren along with a GI pass - Houdini's compositing nodes are used to bring the images together.

Hi,
See the attached hip file - make sure you have the “Composite View” activated, and wait a couple of seconds - the final composite is feeding it's data directly from render drivers (mantra + wren), and layering them together.
After all, I used vex_toon shader, rather than than using the simple_ramp material - it is much less controllable, but very quick to set up.
Cheers,
Greg

Ouups :roll:
I made a mistake. You're absolutely right, I can open hip file with apprentice.
I tought I can't open hip file, because I can't save as hip file.
This software is soooooooooo COOL !
In fact I've don't really understand why they create 2 file format. I don't really see the difference between both.
Now it's time to me to learn more about houdini to fully understand material.
Thanks everybody

.hipnc is the NON-commercial file format while .hip is the commercial file format. Loading a non-commercial .hipnc will always cause your Houdini session to go into non-commercial mode (with watermarked panes, non-commercial limitations, etc). Basically, it just means that everything will work with loading except that you can't convert non-commercial files into commercial ones.

but how come WREN doesnt work for me in the non-commercial edition?? and is there any other good shaders for architectural renderings??

I have a question about the attached hip file.
I can copy the shopnet1 node to a new file and it works pretty well, however, I don't seem to be able to drop down a toon node from the tab menu… even though there is already one inside the shopnet (this is in houdini 11.1 and also in 12.1)
also, i see a handful of other nodes in the help file which seem to not be available (soft toon, krinkle… a bunch of them…).
What am I missing here?
