Thanks. That's definitely an transparency issue. By any chance, can you find out what graphics card the computer has?

^ This, right? :p

A lil note - It works perfectly with classic client

I've found that the intel chip only supporst openGL 2.1. That could be why it's not working out. I'll see to get a workaround for the issue.
Meanwhile, can you try disabling anti aliasing, does that change something?

EDIT: The issue is basically a really old graphics card. ^^

The school is over for this week, ill let you know if turning anti aliasing off fixes the problem on monday.

No problem. Just curious on what causes the client to forget transparancy values.

It tries to tell me something when turning Anti Aliasing on, not sure what.

It looks like that the computer's openGL driver is just too old to render Emps-World. I assume the school computer isn't the newest?
I'm sadly not able to reproduce the issue with my local configuration, even if I simulate your chips' openGL version.

I am not sure how old it is
Doesn't seem too old imo :p

I've applied a client update. Can you check if it has changed?

EDIT: If it still doesn't work, can you try disabling textures in-game and tell me if that changes something?

Tried disabling it, didnt work.

Alright. It just looks like the graphics chip you're using won't be supported by Emps-World. I've googled the chip in some more detail and adding support for it would downgrade the overall client performance.
