I’m loving Houdini shaders and image planes are just icing on the cake. I thought I would run through the basics first then in a later video(s) get into extracting specific data into planes then cover light exports in image planes. So you can find part 1 here!
It’s a fairly straight forward but I thought it needed to be put in video form. Dynamics and expressions in Houdini go hand in hand and this is an example of that. You can find the video tutorial on how to do this here and the result below:
There was a discussion on the Houdini forums that I took part in that I thought was worth not just one video tutorial but a three part series. I think it’s a really simple task but shows oh so much and is easily applicable to more complex work. What it covers is taking an object that will emit particles and dictating what points on the emitter send out particles and in what direction using a bounding object and one of the bounding object’s normals. You can find the videos and completed .hipnc file here.
Here is what the final result looks like (note that I changed the resulting file a bit to get a good flipbook result):
I was so caught up with showing how you can get your grouped points output to a group node I didn’t show the easier way to stitch cloth with the stitch constraint (and an issue that may arise). So instead of calling do-overs and doing the whole video again just to add that, I’ll just do a 2 minute supplement to the video which you can find here.
After seeing the videos that Sidefx puts out (1, 2), I am obviously left with the thought that I’m no where close to the level of “real” Houdini users. But I still trudge along learning what I can when I can, and sharing it here with everyone. Behold then my super beginner video on constraining cloth to a bar… using two different methods!
Here’s an example of the second method using the flipbook:
