The files are ASE models, (which is a text based format) so the
texture/shader path can easily be edited using notepad you don't
need to use any 3D software, just open a file into notepad,
find the texture path references & edit those to 'point' to
your folders / textures / shaders, re-save to a location of your
choice and then load ready textured into Radiant.
If you want to use 'auto clipping' on the models instead of applying
manual Playerclipping in Radiant you'll need to write a shader;
see below for an example of a 'basic' shader that has autoclipping
(change the texture paths as you see fit).
textures/spkat3/cwood_mo5c
{
qer_editorimage textures/castle_wood/cwood_mo5c.tga
q3map_forcemeta
q3map_nonplanar
// q3map_shadeangle 79 // OPTIONAL*
q3map_clipmodel
{
map $lightmap
rgbGen identity
}
{
map textures/castle_wood/cwood_mo5c.tga
blendFunc GL_DST_COLOR GL_ZERO
rgbGen identity
}
}
*note : using q3map_shadeangle on models that have
specific smoothing groups can have some undesirable results, esp
on more 'organically' shaped objects so this is commented out
by default for this shader.
