I have 2 questions here.. D

1)about self illumination. for instance, to create the effect of a moon, light bulb, how to do the self-illuminate effect…?

2)about blending shader. i want to animate a leaf turning from new to die away, I modify the shader for blasted leaf by putting some brown on the new leaf's texture(it is a jpg file). eg

newLeaf -> uvproject1 -> shader1

blasedLeaf -> uvproject2 -> shader2

When i applied the blend SOP for these two geometries, even i selected the Blend Texture option, it only blent the geometries but not the shaders.. why? How can i blend the shaders?

Thanks a lot
