RE: Depthmap for alpha mapped leaves?

["cristobal infante" <cristobal.infante(at)primefocusworld.com>]

How about putting all your leaves in a partition and overriding the "Copy Alpha to RGB"

paramater?. That should work without altering the shader.

 

A while ago I used a slightly different method, I wrote a little script that would loop the render tree and actually tick this option on/off on any material with an image on it..

let me know if something like that would be useful for you.

 

Best,

Cristobal

i would LOVE for there to be an option to intervene instead of just override,
ie instead of completely replacing the surface
if you could jkeep all shaders alpha properties and override their rgb.

give them constant white in the sprite's colour, and put a black volume_fog shader on the pass.

Subject: Depthmap for alpha mapped leaves?

I am doing a jungle shot where many of the plants have alpha sprite mapped leaves. Now I need a depth map, and using etither BA Raylength or scalar state works almost fine with sprites - only problem is a thin line of brighter pixels on the aliased edges of the alpha  - do you guys have any ideas on how I get rid of those?
