Hey, I have a problem with using the mentioned extension. I use the following code and it''s task would be to draw the texture in its ''true'' color, isn''t it? However it draws the texture with blue color... Why is this? glColor4f(1,1,1,1); glTexEnvf(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_COMBINE4_NV); glTexEnvf(GL_TEXTURE_ENV, GL_COMBINE_RGB_EXT, GL_ADD); glTexEnvf(GL_TEXTURE_ENV, GL_SOURCE0_RGB_EXT, GL_TEXTURE0_ARB); glTexEnvf(GL_TEXTURE_ENV, GL_SOURCE1_RGB_EXT, GL_PRIMARY_COLOR_EXT); glTexEnvf(GL_TEXTURE_ENV, GL_SOURCE2_RGB_EXT, GL_ZERO); glTexEnvf(GL_TEXTURE_ENV, GL_SOURCE3_RGB_NV, GL_ZERO); glTexEnvf(GL_TEXTURE_ENV, GL_OPERAND0_RGB_EXT, GL_SRC_COLOR); glTexEnvf(GL_TEXTURE_ENV, GL_OPERAND1_RGB_EXT, GL_SRC_COLOR); glTexEnvf(GL_TEXTURE_ENV, GL_OPERAND2_RGB_EXT, GL_SRC_COLOR); glTexEnvf(GL_TEXTURE_ENV, GL_OPERAND3_RGB_NV, GL_SRC_COLOR); Draw(); Thanks in advance! -- tSG --
