Ok, so to clear things up, this is what happened:
I´ve had a model which used a terrain blending texture (a shader including the dotproduct2 property). Though this model didn´t make any use of specular- and reliefmapping. See the terrain models in the map Warfare for this, they exactly represent this issue.
But this issue is not model specific. It´s related to the dotproduct2 or the blending property. One more oddity shows up when using these shader properties is that BSP structure then supports reliefmapping but not specularmapping.
So misc_models do support specular and reliefmapping but shaders using a blending technique don´t.
Maybe some of you may try this out and we´ll see whether this behaviour can´t be confirmed?
By the way this is the shader I wrote:
Code:
textures/map_warfare/blends_earth_rock01_sand01
{
qer_editorimage textures/map_warfare/blends_earth_rock01_sand01.tga
q3map_bounceScale 0.5
dpoffsetmapping - 9 match8 168
q3map_lightmapSampleOffset 8
q3map_nonplanar
q3map_shadeangle 95
q3map_alphaMod dotproduct2 ( 0 0 1 )
{
map textures/phillipk2x/natural/pk02_rock01.tga // Primary
}
{
map textures/phillipk2x/natural/pk02_sand01.tga // Secondary
blendFunc GL_SRC_ALPHA GL_ONE_MINUS_SRC_ALPHA
alphaGen vertex
}
{
map $lightmap
blendFunc GL_DST_COLOR GL_ZERO
}
}
