How to combine several meshes?

Hello,

I need to create A LOT of meshes, and I need a way to combine them in order to reduce draw-calls.
Is there any built-in way to achieve this in 3DGS?

Thank you for your help!

More precision please !
It is meshes for main level , characters, 3D assets ?

The best way that could suit you , make one mesh of all under your mdeling application and export as one mesh for 3DGS !

I create models ENTITY (3d models) at runtime, so I cannot merge them in 3D modelers.
I can group meshes (small meshes, 16 or 32 units as bounding box per side) as "sectors" (meshes near to each other, located in the same area).
It is static geometry.


EDIT: they are rocks in low-poly.

Have you a screenshot ?
Why the need for creation at runtime ?
I think you can find other solutions by seraching a walkaround !

No, I need to create an environment at runtime. Absolutely.
My game is enterely procedurally generated.
Want an example? Well, check out the game I already made using Unity3d at:

I need to make the second chapter (another adventure, more complex).
So I was checking 3DGS features to make a game like this.

Thank you.

It looks like some Minecraft similar game using cubes.
There is already a 3DGS thread talking about that sort of cubic world :
Cube framework

There are people using Ogre3D , Jmonkey engine that uses their own code for "Minecraft" like.

Yes I know what you said. But my question is still the same: is there any way to combine small meshes to decrease the number of draw-calls?
Unity3D, for example, uses 2 methods: dynamic batching (automatically performed by the engine at runtime), and static batching (PRO version only :'( )

JME 3 (I know that engine) uses a geometry optimizer (even if I got not good results with it). But JME uses scenegraph, very useful in games like this.

Well i'm not sure A8 can do that.
Or you'll have to code a DLL for it yourself ?
Even more i don't know if batching in real time will not slow the game ?

I'm not strong programmer at all

You should post your question in "Engine" thread, you'll have perhaps some answers ?
Why not reading the manual also , all is in it about the engine.

I hope there is a c-script to do that.



Ok, I do it. But is it a good idea duplicating the thread? Can JCL move this thread instead?



Done. There is nothing.

look here(i don't follow this thred so i cant say that it is working now, or not): http://www.opserver.de/ubb7/ubbthreads.php?ubb=showflat&Number=355335#Post355335
maybe you can "copy" your old mesh an add the new to it, u have just merge the vertices(so that you havn't two vertices at one point) and remove the sensless polys. i cant give you an example, sorry. and i don't know how fast it is.
xxxxxxx

I dind't mean duplicating the thread !
I meaned : post your question in this existing part of the forum relatde to the engine :

Engine thread

That's exactly what he meant -- asking the same question in a different forum is usually frowned upon, hence his question.

I think you can request it be moved and notify a moderator (there should be a button somewhere to do that).

Jibb

Ok, thank you, I will search that button :-)

I red the thread related to create new mesh using DX, but it is a mess (I'm not an expert in DX low-level programming).

Thank you.
