Quake3 textcoords

Maybe iam rendering it wrong?
Here is my code for rendering(Iam rendering the whole world no bsp traveling)
for(int i=0;i {
if(i>0)
{
if(FaceList.Shader!=FaceList[i-1].Shader)
glBindTexture(GL_TEXTURE_2D,(FaceList.Shader+1));<br> }<br> else glBindTexture(GL_TEXTURE_2D,(FaceList.Shader+1));<br><br><br> glBegin(GL_TRIANGLES);<br> int felem=FaceList.FirstElmt;<br> int numelem=FaceList.NumElmts;<br><br><br> for(int j=0;j<numelem;j++)<br> {<br> <br> glTexCoord2fv(VertexList[FaceList.FirstVert+ElementList[felem+j]].TexCoords);<br> glVertex3fv(VertexList[FaceList.FirstVert+ElementList[felem+j]].Position);<br> }<br> glEnd();<br> }<br><br>Is this the right way to do it?<br>I also use glScalef(0.1,0.1,0.1) on the modelview.<br><br>Should i do anything with the texture matrix?<br> </i> <br><br>Edited by - Enouk on February 25, 2002 2:43:59 PM

You shouldnt have to do anything with the texture coordinates within the bsp file, as they are correct. Im loading and rendering a BSP file in one of my projects, and I just render the vertices like so:
v is a pointer to the drawVert_t struct (similar to the struct you pasted in your post, except the ''int color'' in yours should be a 4 element byte array).

glMultiTexCoord2fvARB(GL_TEXTURE0_ARB,v->st);glMultiTexCoord2fvARB(GL_TEXTURE1_ARB,v->lightmap);glVertex3fv(v->xyz); v is a pointer to the drawVert_t struct (similar to the struct you pasted in your post, except the ''int color'' in yours should be a 4 element byte array).

the cureved surfaces in quake3 are bezier patches u will need to build the triangles from these, ie the curves contain no triangles
