Hi I've been trying to learn Houdini at home by following this tutorials here:
http://www.sidefx.com/index.php?option=com_content&task=view&id=1423&Itemid=132 [sidefx.com]
I've followed the tutorial very closely and brought in the image to my network however it seems that my point node is always cooking and taking a super long time to playback.
So I tried using tex instead of pic to bring the image in. It works in the sense that now the cooking is gone but it seems like it is stretching the edge pixel all the way across the grid.
I thought perhaps it's the expression I am putting into my point node which is causing this but I'm not sure.
This is the expression I'm using in the point node to indicate it should be adding this color to the particles in the R channel.
tex(“/Users/Sung/VFX/Robot Refs/muppet_man_02.jpg”, $BBX, $BBY, D_CR)
Would someone here be able to lend me a hand with this?
Thank you.
