Hi , I've been trying to implement this in C++: http://www.delphi3d.net/articles/vi...=terraintex.htm However I'm trying to get lighting to work and just don't seem to be able to , I just seem to get Texture2 showing (see code below) Can some one give me some advice. Kind Regards Code: glEnableClientState(GL_COLOR_ARRAY); glColorPointer(4,GL_FLOAT, 0,Colours); glClientActiveTextureARB(GL_TEXTURE3_ARB); glEnableClientState(GL_TEXTURE_COORD_ARRAY); glTexCoordPointer(2, GL_FLOAT, 0, TexCoords2); glClientActiveTextureARB(GL_TEXTURE2_ARB); glEnableClientState(GL_TEXTURE_COORD_ARRAY); glTexCoordPointer(2, GL_FLOAT, 0, TexCoords); glClientActiveTextureARB(GL_TEXTURE1_ARB); glEnableClientState(GL_TEXTURE_COORD_ARRAY); glTexCoordPointer(2, GL_FLOAT, 0, TexCoords); glClientActiveTextureARB(GL_TEXTURE0_ARB); glEnableClientState(GL_TEXTURE_COORD_ARRAY); glTexCoordPointer(2, GL_FLOAT, 0, TexCoords); glEnableClientState(GL_VERTEX_ARRAY); glVertexPointer(3, GL_FLOAT, 0, Vertices); glEnableClientState(GL_VERTEX_ARRAY); glVertexPointer(3, GL_FLOAT, 0, Vertices); //Normals glEnableClientState(GL_NORMAL_ARRAY); glNormalPointer(GL_FLOAT,0, Normals); // Texture 3: previous * L lightmap glActiveTextureARB(GL_TEXTURE3_ARB); glEnable(GL_TEXTURE_2D); glBindTexture(GL_TEXTURE_2D, Lightmap); glTexEnvi(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_MODULATE); // Texture 2: lerp(C0.alpha, previous, T3) glActiveTextureARB(GL_TEXTURE2_ARB); glEnable(GL_TEXTURE_2D); glBindTexture(GL_TEXTURE_2D, T3); glMatrixMode(GL_TEXTURE); glScalef(0.2, 0.2, 0); glMatrixMode(GL_MODELVIEW); //glTexEnvi(GL_TEXTURE_ENV, GL_RGB_SCALE_ARB, 2); glTexEnvi(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_COMBINE_ARB); glTexEnvi(GL_TEXTURE_ENV, GL_COMBINE_RGB_ARB, GL_INTERPOLATE_ARB); glTexEnvi(GL_TEXTURE_ENV, GL_SOURCE0_RGB_ARB, GL_PREVIOUS_ARB); glTexEnvi(GL_TEXTURE_ENV, GL_OPERAND0_RGB_ARB, GL_SRC_COLOR); glTexEnvi(GL_TEXTURE_ENV, GL_SOURCE1_RGB_ARB, GL_TEXTURE); glTexEnvi(GL_TEXTURE_ENV, GL_OPERAND1_RGB_ARB, GL_SRC_COLOR); glTexEnvi(GL_TEXTURE_ENV, GL_SOURCE2_RGB_ARB, GL_PRIMARY_COLOR_ARB); glTexEnvi(GL_TEXTURE_ENV, GL_OPERAND2_RGB_ARB, GL_SRC_ALPHA); // Texture 1: lerp(C0.rgb, T1, T2) glActiveTextureARB(GL_TEXTURE1_ARB); glEnable(GL_TEXTURE_2D); glBindTexture(GL_TEXTURE_2D, T1); glMatrixMode(GL_TEXTURE); glScalef(0.2, 0.2, 0); glMatrixMode(GL_MODELVIEW); glTexEnvi(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_COMBINE_ARB); glTexEnvi(GL_TEXTURE_ENV, GL_COMBINE_RGB_ARB, GL_INTERPOLATE_ARB); glTexEnvi(GL_TEXTURE_ENV, GL_SOURCE0_RGB_ARB, GL_PREVIOUS_ARB); glTexEnvi(GL_TEXTURE_ENV, GL_OPERAND0_RGB_ARB, GL_SRC_COLOR); glTexEnvi(GL_TEXTURE_ENV, GL_SOURCE1_RGB_ARB, GL_TEXTURE); glTexEnvi(GL_TEXTURE_ENV, GL_OPERAND1_RGB_ARB, GL_SRC_COLOR); glTexEnvi(GL_TEXTURE_ENV, GL_SOURCE2_RGB_ARB, GL_PRIMARY_COLOR_ARB); glTexEnvi(GL_TEXTURE_ENV, GL_OPERAND2_RGB_ARB, GL_SRC_COLOR); // Texture 0: T1 glActiveTextureARB(GL_TEXTURE0_ARB); glEnable(GL_TEXTURE_2D); glBindTexture(GL_TEXTURE_2D, T2); glMatrixMode(GL_TEXTURE); glScalef(0.2, 0.2, 0); glMatrixMode(GL_MODELVIEW); glTexEnvi(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_REPLACE);
