You can't intermix standard jitter object attributes with opengl commands inside a jit.gl.sketch command list, unless you're using "immediate" mode (which should probably only be used from JS/Java/C). I would recommend using the corresponding OpenGL calls to accomplish this.

In OpenGL, these attributes correspond to the following C code. Of course, you'll want to convert to appropriate jit.gl.sketch syntax (convert everything to lower case, remove GL_ from the beginning of symbolic constants, etc.).

// texture mapping modes switch (ob3d->tex_map) { case 1: glEnable(GL_TEXTURE_GEN_S); glEnable(GL_TEXTURE_GEN_T); glTexGeni(GL_S, GL_TEXTURE_GEN_MODE, GL_OBJECT_LINEAR); glTexGeni(GL_T, GL_TEXTURE_GEN_MODE, GL_OBJECT_LINEAR); glTexGenfv(GL_S, GL_OBJECT_PLANE, ob3d->tex_plane_s); glTexGenfv(GL_T, GL_OBJECT_PLANE, ob3d->tex_plane_t); break; case 2: glEnable(GL_TEXTURE_GEN_S); glEnable(GL_TEXTURE_GEN_T); glTexGeni(GL_S, GL_TEXTURE_GEN_MODE, GL_SPHERE_MAP); glTexGeni(GL_T, GL_TEXTURE_GEN_MODE, GL_SPHERE_MAP); break; case 3: glEnable(GL_TEXTURE_GEN_S); glEnable(GL_TEXTURE_GEN_T); glTexGeni(GL_S, GL_TEXTURE_GEN_MODE, GL_EYE_LINEAR); glTexGeni(GL_T, GL_TEXTURE_GEN_MODE, GL_EYE_LINEAR); glTexGenfv(GL_S, GL_EYE_PLANE, ob3d->tex_plane_s); glTexGenfv(GL_T, GL_EYE_PLANE, ob3d->tex_plane_t); break; default: glDisable(GL_TEXTURE_GEN_S); glDisable(GL_TEXTURE_GEN_T); break; }

Hope this helps.
