It still looks good, but any sharp-eyed individual will notice the tiles within seconds. This isn't a really big issue unless you get to see most of the moon's surface.
You don't say. Hey, if you know a way to make a large slab of polygons like that look good without using a bazillion textures, why didn't you tell us?
Is it possible to have two textures one on top of the other in any way?
If it is (and I mean in *any* possible way... perhaps Valathil could help us here), the effect can be substantially improved.
This is exactly how I deal with these problems when they appear in my architectural renderings, for instance with grass. I need both a very good texture up close but something else that stops the far away mesh to appear like a tiled carpet. I do this with two textures on top of each other, the one on top with 50% transparency. I use one texture with 1 meter (+-) in size, the second 10/100m in size (depends on the project). The first deals with the fine texture, the second deals with shades of colors, diluting the tile effect. The solution is perfect.
Is this anyway helpful? I know you can't simply put a texture on top of another, but perhaps with an effect?
