FX-Scripts

[Q3mme running out of fx_megs.]

Hello All,

as the title says i got some issues with q3mme and custom fx-scripts. For the Rocket-Impact i want some flares which are emitting particles themselfes. However at most rocketimpacts my q3mme crashes. Telling me Q3mme running out of fx_megs. Increase the value. Sure i tried to increase the value from 2 to 16 to 32 .. 512. Wont make a diffrence. I got recently told that this might occure with "cutted" demos but i got that issue on cutted and complete demos aswell. However this is the scriptsnippet which is responsible for the crashes:

pastebin.com/VsHiH2N2

Any ideas?

Greetings

Hello farnish,

I cannot help you with this. I hope the next person after me answers this for you, good luck!

o/ farnish,

q3mme crashes when there are too many entities in the scene. It's not like your computer can't handle it, but the engine can't manage that many entities!

What you can do is:
-reduce the entity count.
-instead of having a shitload of entities, make the illusion of having them, while actually using much less of them.


Here's an example:
One would say when he see these explosions that the entity count must be really high. But if you look closely...




..
you realise that they're texture layers :^D
And the trails use a custom texture to give the effect that it's waay more complex.
I'd be surprised if the entity count is higher than 2000. Even 1000.

Actually, games nowadays are like this. (aka "making an efficient use of resources")

I could write a more complex post about this, but I'd rather make a thread in that case .

Cheers

ps: legless or renk could give you a more clear and clever idea of what I mean.

Max of fx_Megs is 8: sourceforge.net/p/quake3mme/code/HEAD/tree/trunk/code/client/fx_main.c#l1548. I can increase that limit if necessary, but be sure you are not going into requirsive emitter callings which makes endless amount of entities.
And yeah, as Santile said, try to emulate big amount of entities with textures.

You're trying to make a rocket/explosion which emits some sprites, which in turn have a trail? Like ?

In that case I don't see the fault in your script, it shouldn't create too make sprites or be recursive. Try changing the distance to 3 rather than 0.3, which is unnecessarily small.

There seem to be a couple mistakes though:

You used the variable parentvelocity, but parentvelocity will be 0 for a rocket impact. Also you didn't specify a model, but you used the command 'anglesmodel'.

I use wolfcam, which doesn't let you script after writing a render command such as anglesmodel, so I'm not 100% qualified to critique your script though.

I can upload the code I used in my above screenshot if you want.

Q3mme has got looots of bugs compared to wolfcam. Scripts simply crash for no reason many times.

My rocket explosion, hope this helps.

Thanks guys for your replies.

@ eq: Exactly this is what im planning to set up for my scripts. I tried the change of the distance didnt helped much though. If you dont mind i would give your shaders a try.

@ legless: Thanks for sharing the script code. You propably created those shaders for QL, so im not sure if they would work. But i cant try them since you created your own shaders files i belive:

Missing

lglsSmokeCloud
lglsMark1
lglsMark2
lglsMark3
lglsMark4
lglsMark5

..
 
Would be glad if you could link them aswell.

Thanks guys and have a nice weekend

Sorry, i wont release my shaders.
Just replace them all with sunFlare just to see how script works.

Ok, ill give it a try right now

fxError: ' Unknown Token t5' in line 't5 0.2 + rand*0.2' in script 'weapon/rocket/impact'

Propably some variables or definitions not allowed in q3mme?

You propably used Wolfcam?

[legless]

Aw, you're right, this is for wolfcam.

Try this? It's the part where particles with trail are emitted.

If this wont work, then i guess you have to make them with textures as santile described here.

(but im not sure if q3mme supports big animmaps which are needed for this)

[farnish]

I just tried to reduce some of the effects like explosions light and some Sparks.

I tested this script:

pastebin.com/uHHHi0zx

and if i passed through the demo almost frame for frame i recognized this :

postimg.org/image/rcp7zogvt/

So i think some variables or functions are ******ed??

Ill try your suggestion now aswell

[farnish]

For your script: I had to remove the 'sink 0' But q3mme crashes at every explosion :/

Farnish:

Here is a link to my fx code and shader for the stone. And here is a (probably temporary) link to the skin and model for the stones. They aren't mine, I think they came from someone on this forum...ferrbaes or something maybe?

The fx script is mine though.
