Questions about using 3D in Director
Shader query - detail maps
Posted by: MjMAC87 (---.cmbg.cable.ntl.com)
Date: June 23, 2010 12:24PM Hi all.
I am looking to see if it is possible to create a shader that is built up from a detail map. For instance, I have 4 textures, grass, rock, sand and stone. I have an RGBA map which reflects how much of each texture to use. For instance, pixel 53 x 87 on a map that is 128 x 128 would have for instance, 195R, 0B, 25G, 35A, which obviously reflects how much red, blue, green and alpha to use. So technically R would mean that the grass texture would be almost completely visible but with a hint of sand and stone. From what I have read so far from what I have found, a shader in director can consist of 8 textures. Am I right in thinking I would set the blend mode to use alpha meaning I would need 8 layers where a blank with an alpha map of where the grass should be? I am familiar with vertex shaders etc to do this, but not within Director. I am just wondering if there is any resources on it out there or if anyone has any idea themselves before I leap in and try to do it from scratch. Thanks in advance, mjmac87 Re: Shader query - detail maps

I have a terrain texture blend vertex and pixel shader to hand if that will help give an idea as to what I am looking for? Re: Shader query - detail maps

Date: June 25, 2010 01:12PM sounds like you just want to blend some textures together. if you can get the vertex blend and the pixel shader into a texture. you should be able to do that without a problem. you dont have to wait until you get into director to do it. you could import it in that way
you might find this interesting www.bleed.110mb.com/femalebodypainted.htm Edited 3 time(s). Last edit at 06/25/2010 01:18PM by tyree. Sorry, only registered users may post in this forum.
