This Camera Creation Script creates a camera with lots of useful feedback.

-Camera Frustum

-Compensation for Aspect Ratio

-Clipping Planes

-Cropping

-Camera Window Sizing and Shearing

-Focus Point

-Focus and Camera markers scale by the Focus amount for easy viewing.

-And Lots Lots More... well not really.

To use simply place this file (cam.cmd) in your $HSITE/houdini<version#>/scripts/obj or $HOME/houdini<version#>/scripts/obj Directory.

Try it, you'll like it.

I updated this to work with Houdini12.1

This file contains a fruitbowl model that came from a lighting challenge on CG Talk. The idea was to take the model and create a composition with full custom lighting. Lights and textures were not supplied. This scene file includes the imported geometry, Houdini lights, and a group of shaders built using Vex Builder. The final image was rendered using Mantra. I only put a little time into this composition therefore the shot is only partly completed. The goal was to introduce the lighting challenge participants to Houdini's lighting and rendering. We invite other users to download this file and take the shot to the next level.

This operation mirrors geometry where only one half has been modelled then lets you subdivide the resulting shape. You can also use this operator to support a subdivision modeling workflow where you can work with a wireframe of the one half while previewing the results with shading.

Refer to the asset's help card for a quick how to use this asset.

This Pattern Generator OTL can create both 2d and 3d designs based on extremely simple L-System Rules.

A few notes/suggestions:

-Wireframe View looks best if you're just doing a skeleton.. (Cleaner lines)

-Expect high Generation values. Default is 1000 but any machine made in the last few years should be able to handle 10,000 without too much of a cook time.

-Leaf Inputs are available, but i didn't implement stamping on the inputs.

-I made about 10 presets to look at and play with in case you want to quickly see different types of patterns it can generate.

A python script to convert a sequence of obj files to a .pc2 file. This allows exporting animated geometry from Houdini into 3D Studio Max. This only works for deforming geometry where the point count does not change (won't work for particles!)

Usage: obj_2_pc2.py [-h] [-s startframe] [-o outfile.pc2] [-r] [-f samplerate] objfile .. objfile_n

Convert a series of obj files to a single .pc2 file

Command line options:

h - show help on usage

o - provide output .pc2 filename, default is constructed from first obj file

s - provide start frame for .pc2 header, default is 1

f - provide sample rate for .pc2 header, default is 1

r - do not rotate, (x,y,z) does not become (x,-z,y)

Examples:

$ obj_2_pc2.py myobjs.*.obj

$ obj_2_pc2.py -r myobjs.*.obj

$ obj_2_pc2.py -s 101 -f 2 -o sample_rate_of_2.pc2 myobjs.*.obj

Quickstart:

1/ export your sequence as objs with a Rop Output Driver Sop.. make sure you used padded file numbers (eg. myobjs.$F4.obj)

2/ run the obj_2_pc2.py script passing those objs as arguments.. (eg obj_2_pc2.py myobjs.*.obj)

3/ Import the first obj into max

4/ fix the geometry up (add Normal modifier and smooth modifier with auto-smooth)

5/ attach the myobjs.pc2 point cloud to the imported geometry with the following plugin:
