2 annoying texture issues

Hey all,
i've been working on a new duel mode which takes place on an island an so on. But at the mment there are 2 very annyoing mistakes there. Just by the way it's one whole prop (the duel track). There is the main ground, there are the side backgrounds and some walls. The more detailed palm trees in the picture are just animated props.

Anyway my two issues are that...
that the middle ground texture looks..I can't find any words to describe that. It's like that the points you can move in texture editor have been moved while munging. All the bugs are only ingame btw.

and that the side backgrounds which have transparency textures are invisible. Not completely. Just like 50% of the whole color is gone. You still can see the texture but it's sometimes invisible.
Hidden/Spoiler:

I hope you may know why this is happening. If you need the model to take a loot at it then just write it down here.
Thanks in advance.

Are the billboard trees using a custom model or a stock one with a new texture?
Check the alpha channel of your texture. Also check the flags of the model to ensure there are no weird transparency properties turned on. HERE if you want to hex-edit, or HERE if you are going to use XSI.

Regarding the terrain... is that a model as well or is it an actual terrain in ZE?

The terrain is a model (merged with the billboards), made in xsi.

Unfortunately I can't help with the ground texture... that's actually a problem that I'm having with some of my models as well and I haven't been able to figure it out.

Did you look into the alpha channel of the billboard trees?

Hey thanks. The billboard bug is now fixed. Thanks to hex editing. :D

Because of the ground texture: Does it matter how large your object can be? For example a model with the lenght of...1000m? Or more. I just would like to know if there was a limit or something like that because the track is very long. I am not in mind to short it a little bit. It just interests me if there was a scale limit or so on..

I'm not too sure. Each time I've seen this kind of texture distortion it has been with a low-poly object that is over 50 meters across. Now that I think about it, it might be that very large polygons have issues when their UVs get munged. Maybe try subdividing the track a little bit?

Hm I could try to add more edges which coneect some points, or adding them via the Knife Tool. If thats the reason then I can keep the lenght. Thanks for your reply. I will try that tomorrow.

Often that texture bug is from when one polygon is a great deal larger than the texture. Try subdividing the polygon into smaller chunks.

Indeed. Besides, entirely flat, overly-large planes like that without really any tessellation whatsoever won't be lit or shaded well anyways - unless of course you use per-pixel lighting in the mesh's material(s), which can be expensive but gorgeous. :P
