tex_env question

Recommended Posts

Hi there, I'm using this on texture stage 3
glTexEnvf(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_COMBINE_EXT);
glTexEnvf(GL_TEXTURE_ENV, (GLenum)GL_COMBINE_RGB_EXT, GL_MODULATE );
glTexEnvf (GL_TEXTURE_ENV, (GLenum)GL_SOURCE0_RGB_EXT, GL_PRIMARY_COLOR);
glTexEnvf (GL_TEXTURE_ENV, (GLenum)GL_OPERAND0_RGB_EXT, GL_SRC_COLOR);
glTexEnvf (GL_TEXTURE_ENV, (GLenum)GL_SOURCE1_RGB_EXT, GL_PREVIOUS);
glTexEnvf (GL_TEXTURE_ENV, (GLenum)GL_OPERAND1_RGB_EXT, GL_SRC_COLOR);
This acutally means the value of the texture set for this stage isn't needed but when I do not bind a texture to this stage it is disabled completely and the computation isn't executed. Do I really have to set a texture for this stage (dummy texture)? Thanks Markus
