I have found your tutorials really helpful in the past and this one seems to be no exception! New-comers to the joys of Apophysis are able to follow them, so I direct them here to help new artists get a feel for how the program runs.
Thank you for taking the time to craft these wonderful tutorials!
When you did step 2, did you include bubble 0.5? this gives it a raise look. Also it's a good idea to move the transform around. Just grab the triangle and move it around. If this doesn't work I'm not sure what could be going wrong. Are you using Apophysis 3D? not Apophysis 2.08/2.09?
