3d sprites:

2. meshes with a plane

colorkey :

makeColorKeyTexture or use an alpha channel and EMT_TRANSPARENT_ALPHA_CHANNEL

As the above poster said, read on the general theory of billboards and then try to use irrlicht billboards. It's simply a quad with a normal vector pointing toward the screen.

No. no. The object is a tree. Isn´t necessary face to the cam, and I don´t want too. Billboards use 2d positions, so useless!

why dont you read what dark rain has posted above? i think you are one of the most stupid persons that one can possibly find here at the forum. this whole thread is rediculouis. im sorry but its the truth

but maybe god is with us and you just try to open your eyes and read what we posted (maybe even actually take a look at the irrlicht tutorials - but no, that would be too much of an effort

)

see you!

thanx for all.

I go to ignore this because it is a Begginer forum.

its not only laziness, you just dont read what other people tell you when they try to help lol - thats even worse

the thing you look after with irrlicht is called IBillboardSceneNode.
irrlicht has an api documentation (in .chm file) where you can type in keywords so they get you search results.

im sure when you go to your irrlicht directory, then go to "docs" and open irrlicht.chm, you will get the irrlicht api doc. click on "index" and type in "ibillboardscenenode" - done.

note: billboards in irrlicht always look to the camera, if you need billboards that do not fade you have to decide what you want:

1. implement axial-billboards
2. use a mesh with a simple plane and give it the tree texture, thats basically the same thing a billboard does, too.

i really hope you read this post because it should contain any information you need

see you!

I don't think that's going to work. If you can't by yourself guess the concept of quads mapped with a texture, well you need to read up on a lot of 3d theory and no amount of 10 line posts is going to help. That's my opinion at least.

It is this that I did not want to make.

Really thanx "Dark".
