Bryce 7 materials?!

Why are my materials so pixelated? The textures always come out as squares of texture, it's not smooth at all. You can see it in the texture of the lower left corner of the bluish picture, on the land; on the red and green picture, on the mountains in general (especially prominent on the right hand side). Also, in the second picture, look at the reflection of the water. It's totally messed up! What's going on?

    It might be that the textures were meant for things of a different size then what you're applying them to and as such you need to adjust the scale of the texture by selecting the edit texture option in the transformation tools for the material in question when you're in the Material Lab?

    Make sure you have Anti-Aliasing on in the Render Options.

    Looks to me like it is the heightmap resolution of the terrains that is creating the pixelation effect. Normally the heightmaps generated internally achieve 16 bit greyscale resolution, however, depending what filtering is used, some effects cause the map to drop to 8 bit - but since it is expecting 16 bit and is sampling for 16 bit this results in a stepped heightmap. I cannot positively confirm that this is what is happening in this case, but that is what it looks like to me. If you want positive confirmation, post me one of the source files and I will tell you exactly where the problem lies and how it can be fixed.

    If you want to do that.

    Another thing it it could be (is most likely to be), is the resolution of the terrains you are using.

    Pic 1: Terrain set to ultra fine
    Pic 2: Exact same scene but with terrain set to Gigantic resolution
    Pic 3: Terrain Editor resolution option

    Edited to add; Or what David said. :)

    Okay. I'll try these options. Secondly, why is there so much noise in my renders?.. typically I render them in .pngs because they take up a TON LESS space than bitmaps...

    and how can I fix the water texture? Look at how messed up/ UN realistic it is (even for Bryce standards)... it's just basically noise with a striped pattern...

    Save the render as BMP or TIFF. PNG and JPG compress the files with a lossy algorithm, meaning you lose a lot. Saving memory on a rendered picture is saving at the wrong place. To publish, use jpg or png, but not for originals.

    The appearance of water is largely dependant on its environment. So if you wish to achieve realism in this respect, then consideration should also be given to what is going to be reflected and what lighting is provided.

    I've made a few video's on this topic which might be helpful - depending on your level of experience with Bryce.
