I'm having problems with decals since I've started working with A8.
First I've faced problem with decal shadows, it looks like they have ZNEAR flag set on them
And this happens with particles as well, they disappear if there is a decal shadow on the background.
Another problem with decal that I've faced, is that they really have ZNEAR flag set on sometimes
One more problem I've faced is this one:
All sprites have proper alpha channel, and it worked flawlessly with A7, so there is nothing wrong with script and sprites as well.
I asked on the forum, no one can fix this, and I'm not the only one who faced this problem.
Some dude told me to read manual... and all of my stuff will work flawlessly, I do my best, but this one still doesn't work...

Please read here about how to use decals properly:

http://manual.3dgamestudio.net/ent_decal.htm

When particles disappear when you see a decal shadow, your particle number is too small. Either limit your particles and decals or increase the particle number.

Z-beating and elements appearing through walls are caused by a wrong clip_near/far range. Use careful level design and don't tamper with the view range settings. Otherwise increase clip_near and reduce clip_far until the problem is fixed.

I think this should be easily fixed by yourself - if not, please post again and we'll help.

Thank you, I've already tried to fix this myself (and not only me I guess):
Thread link
I've played with "clip_near" and "clip_far", but no results..
I've increased number of particles (actually, when I faced problem, I was using too much of them already), same no results...
I can post my script that I use to create decals, if needed, I think I'm using them pretty properly (worked great with A7).
Plus, one more question, why does model disappear if there is a decal shadow under it?

If you can't fix the problem yourself, please contact the support - they'll help fixing the level. Please prepare the level so that all view settings are at default, and the particle number is sufficiently high so that all your decals and particles are visible. Upload or send the level to them and they'll look into it.

OK, thank you.

I've managed to fix the problem, but the result isn't that good...
Here is the demo I've wanted to send to support team:

I found out, that I can fix most of the problems if I rice "clip_near" to number around "5".
But then I face another problem, like this:
I would like to know how to avoid this... Do I still need to send anything to support team?
BTW, "clip_near" doesn't fix this problem:

the second problem is because lot of decals are in the same position, thats a common problem that doesn't happend just with decals, try to place models or blocks with their surfaces in the same place

Dude, try the same in A7! Different result.

The first problem normally gets solved with clip_near, but i think in this case you model is too small, try to scale it up with MED

Shouldn't turning off writing into the depth buffer for the decals solve that last problem?
