i did not read the whole topic, sorry. it was too long. i guess your problem is the alpha sorting, right? you tried the improved overlay from the wiki, and it did not work. did you try
Code:
material alpha_sort{
effect="
texture entSkin1;
pass p0 {
texture[0]=<entSkin1>;
zWriteEnable=true;
alphaBlendEnable=true;
}";
}
action alphaTree{
my.material=alpha_sort;
}
assign the action to your tree.
for a test tree, visit loopix´ site (just go to his profile and click his hp link). his trees do definitely work with the script.
ah, and btw: what happens if you delete all unnecessary template scripts from the <include> lines at the very top of your script? i one had a problem with shaders, and after deleting them, everything worked fine.
