I'm in a bit of a stressful situation, and need some help. I'm working at a small Swedish game studio arrowheadgamestudios [arrowheadgamestudios.com] as a new and the only vfx artist. I used to be be an 3d artist that turned in to a level/world-designer, so I'm a newb and have no technical knowledge and very little code understanding. The studio is looking for a real vfx artist and a technical artist, but until then I'm alone.
The studio bought Houdini for me to be able to create all the flippbooks for many of the effects we will need.
And there is just so few tutorials out there that shows how to create things from start to finish when it comes to game effects, except the few but excellent Andreas Glad tutorials out there.
So to my first problem, after I followed the “HoudiniVFX for Games” on pluralsight I noticed I can't render out images with an alpha channel, I get vertical lines all over the picture I found this to happen with anything I tried to render, it didn't matter if I use tga or png. I also tried to use the GameDev Texture Sheets rop, but same thing happens. Anyone knows what can be happening and how to fix it?
Second problem, anyone know of a tutorial or a way to make sweet surface hit effects from bullets, hitting sand, dirt, gravel and so on?
