I want to create a conveyor and i am using the "entity.u" property.
That does not work!

In the manual:
The pixel offsets of map entity textures, in horizontal and vertical direction. By changing these offsets in real time, effects like streaming water can be achieved. Note: this parameter is not used anymore in newer engine versions, but can be set as a workaround for the DirectX mesh animation bug (see bugs).

Is it right that i cannot use it anymore....?

(I have got 6.60 extra)

Don't ask... just try
my.u += 5 *time_step in loop and You will see is this working or not
For me... works fine

And you have got the latest version (6.60)?

Try or Ask Conitec... but this is tragedy... this was very usefull
and working good so far...
I will not upgrade.. I'll stay with 6.40 for this reason

I agree Tompo, it was convenient I wish they would have left it in, but don't
let that keep you from updating. You can use fx_uvspeed() from the template
"mtlFX", or create a similar function to do this same effect. It is supposed to
be faster.

the wiki's your friend (and HeelX, of course ) http://www.coniserver.net/wiki/index.php/UVShiftingAndAlphaClamp

The problem is that I have only the Extra version -> No Material-Effects support!

Is there another way to do it?
