Multitexturing prob....

Recommended Posts

Hi, im having problem''s multitexturin in opengl. my main problem is that when i assign a texture to my seccond TMU it doesnt do ne thing all i c is the texture from tmu 1. Does the texture in the second TMU have to be in any particular format or can i just use ne texture???...i think ive set if up right ... theses are global: #include "glext.h" #....... PFNGLMULTITEXCOORD2FARBPROC glMultiTexCoord2fARB = NULL; PFNGLCLIENTACTIVETEXTUREARBPROC glActiveTextureARB = NULL; PFNGLCLIENTACTIVETEXTUREARBPROC glClientActiveTextureARB = NULL; these go in a function: mglLoadTextures(0,"ZeroTex.bmp"); mglLoadTextures(1,"lavax.bmp"); glMultiTexCoord2fARB = (PFNGLMULTITEXCOORD2FARBPROC) wglGetProcAddress("glMultiTexCoord2fARB"); glActiveTextureARB = (PFNGLACTIVETEXTUREARBPROC) wglGetProcAddress("glActiveTextureARB"); glClientActiveTextureARB = (PFNGLCLIENTACTIVETEXTUREARBPROC) wglGetProcAddress("glClientActiveTextureARB"); this goes wherer i want to draw: glActiveTextureARB(GL_TEXTURE0_ARB); glEnable(GL_TEXTURE_2D); glBindTexture(GL_TEXTURE_2D, texture[0]); glTexEnvf (GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_COMBINE_EXT); glTexEnvf (GL_TEXTURE_ENV, GL_COMBINE_RGB_EXT, GL_REPLACE); glActiveTextureARB(GL_TEXTURE1_ARB); glEnable(GL_TEXTURE_2D); glBindTexture(GL_TEXTURE_2D, texture[1]); glTexEnvf (GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_COMBINE_EXT); glTexEnvf (GL_TEXTURE_ENV, GL_COMBINE_RGB_EXT, GL_ADD); glBegin(GL_QUADS); glMultiTexCoord2fARB(GL_TEXTURE0_ARB,0,1); glMultiTexCoord2fARB(GL_TEXTURE1_ARB,1,0); glVertex3f (-0.25, 0.25, 0.0); glMultiTexCoord2fARB(GL_TEXTURE0_ARB,1,1); glMultiTexCoord2fARB(GL_TEXTURE1_ARB,0,0); glVertex3f (0.25, 0.25, 0.0); glMultiTexCoord2fARB(GL_TEXTURE0_ARB,1,0); glMultiTexCoord2fARB(GL_TEXTURE1_ARB,0,1); glVertex3f (0.25, -0.25, 0.0); glMultiTexCoord2fARB(GL_TEXTURE0_ARB,0,0); glMultiTexCoord2fARB(GL_TEXTURE1_ARB,1,1); glVertex3f (-0.25, -0.25, 0.0); glEnd(); ne help would be apreciated. thnx Click to goto my page
