@Tul_ Ahh, now it makes sense. I assumed you were using a tiling texture. But if you use a "custom" texture, you always want enough edge padding, or else mipmapping will cause seams. because the lower res texture makes the white bleed through the uv borders. You can fix this if you have photoshop and xnormal. Just look up…
@Doug: Diggin the crystals, Can you explain your thought process for choosing Spec/diffuse color combo? Is it physics related? or did you just mess around till you found something that looked good? Nice work.
Nice to see some stuff from you man! I'm digging your well's style. My suggestion for you, is to add more ambient occlusion and color variation on your textures. You are on the right way man! Looking forward for more updates :)
