Sprites in LODs

[VeTaL]

Is it possible to use sprite as one of the last LODs automatically?

For example, i have model.gmf(500 polys), modelLOD1.gmf(100 polys), modelLOD2.gmf(40 polys) and a sprite modelLOD3.gmf(1 polygon) (?)

 

Not a concretic proposal, just this idea strikes my head

 

PS: maybe this is already supported as i see something like this in forest demo, when flying up and looking down on the trees.

I think its already supported.

from 2.12 vegetation in island demo were placed one by one (as other objects) and they used billboards as their last LOD.

Billboards are already automatically generated for vegetation layers.

[omid3098]

I think he was not referring to vegetation only..

[VeTaL]

Yep, i mean just usual using of sprites instead of models. Maybe even automatically, like trees.

Well, maybe i can create empty model with LUA script, that would load sprite?

 

BTW, maybe its little offtopic, but how can i use billboards? For example, i want sprite on the wall and so on. I found only coronas, but they are "Coronas are simple entities, like billboards, that are always facing the player."

Is there a simple sprite, or it would be nice to have Faced parameter, wich would select if corona facing the player or not.

if you want to get effects like sprites in 3d max, you should use decals on models your models.

you can check gun decals in previous versions of LE.

or you can create in file Lua, a function to make this:

 

Verify the camera to model distance, and Free Entity model, and load a sprite with texture of model, like a billboard...but improvised..

Ah, here it is

[Josh]

This is not supported.

I dont think that its a good idea to cycle all entities in a loop and see if its time for some of them to change at billboard... Maybe in another thread...

 

Then, maybe its possible to catch event, when LOD is changed?

Hello Vetal, i think you can write a function that detect change of LOD with this command: http://leadwerks.com/wiki/index.php?title=Models#GetModelDetail
