Forest Path

I’ve been obsessing over natural environments lately, developing my workflow for plants/trees and techniques for object placement. Maya, Mental Ray, Paint Effects, Onyx and a little Zbrush for the path. 110 million polys. Rendered with physical sun/sky and all miaMaterialX. Surprised by how many polys I can throw at Mental Ray!

    Most amazing botanical work made with maya/mr i’ve ever seen.
    I think this surpassed alesandro prodan’s work on farnsworth house.

    Have you any plan to make a tutorial on this workflow.That will be great.

    I would be awesome to watch some tests with wind physics simultation to the scene. Great work as always

    Incredible work man, you are clearly very passionate about your work :) I would like to send you some images of a short film i’m part of, which takes place in a enchanted forest.I also have a link for you to a short film that we recently finished which also made it to the Toronto International Film Festival.The two projects are styled for animation, so it’s not VFX type work, but i’d like to share it with you to hear what you think.I specialize in lighting, shading and compositing.Lightwave is currently my weapon of choice, but i am also familiarizing myself again with Maya, as i’m looking to get some international experience and most places i’ve seen use Maya.

    I don’t know why I bother even trying to save money when you go and post incredible stuff like this and then offer tutorial DVDs on it. My hand clicked “Buy” before I even finished reading the blurb. This is some beautiful stuff.

    A few comments about second recent dvd. When you talking about how to place an abject on a surface that orient itself according to the normal of that surface I think your expression is not clear and there was some unnecessary assignments to the variables.

    For example :
    your code :
    // orient the instance
    particleShape2.aimDir = $normal;

    In the particle instancer node you assigned Aim Direction to aimDir.

    This assignment is not gonna do anything since Maya is gonna ignore this assignment due to the fact that you assigned rotation to something else (Maya only reads the first rotation assignment out of three and I learned this from you). This confused me in the beginning and I had to go back to Maya’s documents to make sure I remember things correctly.
    Now the $normal vector, according to assignment you made your dvd, is the projection of the a UNIT vector that is perpendicular to the surface on at a particular point. Since it is a unit vector then its projections on the x,y and z are gonna be between -1 and 1 and hence it can be described by sin and cos (any of these function would be sufficient to describe these values but these is an optimal choice for our purpose which is the sin function imo ).

    In the next expression line you want to figure out the rotation around x,y and z so that to assign these values to to Rotation in the instancer node. Your expression is the following :
    // solve each angle, convert to degrees
    float $rotX = rad_to_deg( atan2( ($normal.z), ($normal.y) ) );
    float $rotZ = rad_to_deg( asin( -($normal.x) ) );

    I think the first part is not unnecessary and you could have written that just using the asin function as follows:

    float $rotZ = rad_to_deg( -asin($normal.x) );

    float $rotX = rad_to_deg( asin($normal.z) );

    then do the final assignment to Rotation exactly as you did in your dvd. (no need for the Aim direction) i.e.

    particleShape2.rPP=<>;

    This expression, however, (yours and mine I explained here) has one serious drawback in some situation. This assignment only works when the vector of the $normal vector of the surface points UP in the positive direction and it is gonna give you completely wrong results in case you want to have some normal vector that points down. This is due the fact that the the range of asin is between -90 and 90. To fix this you need to define Rotx and RotZ by some if statement according to the sign of the $normal.y. I do not meant to lecture you Alex, you are my teacher in Maya after all, but I thought posting that would be beneficial for everyone. Thanks for the DvDs and if you like I can send you my file. Thanks again.

    in my previous comment i meant :

    particleShape2.rPP=<>;

    instead of
    particleShape2.rPP=;

    Sorry for that.

    Excellent tutorial and great choice of subject matter.

    Is there a way to effectively convert the Onyx meshes to Quads and further reduce the tree resolution?

    Outstanding work!!! I was speechless a few minutes when i first saw the trailer. Makes me wonder what you could do if u would go for a blockbuster movie like avatar with this technique for vegetation creation but i can bet it would have no big problems. I think this dvd series really shows the real power of mental ray on big production scenes scenario. I work for 10 years with mental ray and other render engines but still continues to surprise me, and always i see i have underestimated the speed and power of this render engine.

    Make particle instances orient to surface normal???? mate i can’t get this right!!!! why????? i did everything you asked and dont get any kind of errors! Am on maya 2011

    every expression seems to execute, nearestpointonmesh loaded..but when i play it, only the random rotation is working. the object in the instancer don’t respect the surface normal!! please help
    thanks
