Texture displacement after tiling

bambusowachata

Hello,

I have problem with texture (look at this texture displacement between two parts, part2 is placed too far to the right) on tiled terrain:

My steps in Bryce:

1) create terrain
2) in editor set 64 size of heighmap
3) create 4 tiles
4) set material and repeat tiling atribute for each tile
5) check render in Bryce -> everything is ok
6) export each object as *.obj
7) set texture 512x512 and tiff
8) import to blender, set materials

There is any solution how to export tiles in *.obj without this displacement?
Thx.
Regards.

It appears that you didn't use the appropriate mapping mode. Here are two videos about tiling
Tiling Pictures on a single object and Tiling Objects which may help you.

I check it but nothing changed. With "world space" texture mapping mode everything is ok (in Bryce) but in bledner not. This is some kind of constant displacement (overlap??).

Something to keep in mind when using Blender/Bryce is that axis designation is not the same. Blender follows what you'd find in Algebra, where X is left to right, Y is top to bottom, and Z up to down. Bryce keeps X as left to right but Z is top to bottom and Y is up to down. This difference might be the problem you're encountering.

To export terrains or lattices you need to handle the capture of the material channels very carefully you cannot trust Bryce or DS to handle this. I've had a lot of trouble overcoming very similar issues myself, you can find my solution in this video.

If you want to see how I came to the conclusions I did, there are more details to be found in the previous five videos on this topic.

Maybe that will help?

Ok, now I know what's going on.

There are dependencies between texture resolution (in export), grid resolution and terrain size.
Example:

1) grid - 128, terrain size - 30x7x30 (one part), texture 1024x1024.bmp - no displacement

2) grid - 512, terrain size - ~80x20x80 (one part), texture 4096x4096.bmp - no displacement

Thanks for your help.
