Irrlicht Engine

Do you mean different nodes with transparent materials?
Cell is a Lightmap material.
Red plane is a Trans_Alpha_Channel material.
Ring PS is a Trans_Add_Color material.

Should i use Trans_Alpha for the PS too?



Yes, use only trans_alpha or only trans_add_color.
I mean, that using one type of ...

Hi,

lets say i have 1 particle system with EMT_TRANSPARENT_ADD_COLOR as material type. Lets say its rendered over a EMT_TRANSPARENT_ALPHA_CHANNEL material.

At certain angles of the camera, the render is done different. It seems to be a problem with render order, but dont know if it is expected ...

Great! Thank you! Main problem was in z-buffer, that cuts some transparent points.

2 ElementoY: only two types are used in the scene: EMT_SOLID and EMT_TRANSPARENT_ALPHA_CHANNEL with MaterialParam setted to 0.1

Thanks to all.
I'm idiot because I don't do z-sorting for particles.

OpenGL, Win32, irrlicht 0.14 + irrSpintz 0.12

In a scene I have lots of objects of EMT_TRANSPARENT_ALPHA_CHANNEL material type : animated meshes and particle systems (all particle system classes are updated from irrSpintz project)
MaterialParam is always set to 0.1.

All animated mesh scene nodes ...

It's culling problem, I think.
Yesterday I try the commented code - "more exact" version of culling. Some nodes began to disappear. Seems like huge size leads to the situation, where culling bug can be noticed.

I was using render to the texture. Found this problem. Cut off everything from the code. Problem hasn't disappeared. That all.

Closed.

Is it normal?
That light options change on next drawAll()?

OpenGL

Simple code (read comment)

And do you have any ideas how to optimize engine by the memory?
Scene with 13 000 triangles and 1,5 mb of textures (OpenGL mode, X Meshes) is eating about 100 Mb of RAM.

It's good, but we need crossplatform, so can work only with OGL.

Hmm, I tried MView and now it gives about 23 fps instead of 15 :D
What optimizations from this utility you've used?

P.s. Oops, I have sent to you only one layer model. Without road and transparent stuff, like tree crowns.
But that ...

Nice scene.

I've been looking into the OpenGL stuff in the IrrSpintz thing as well, but given the fact that Spintz is getting decent (very decent) framerates - I am not sure where the issue is unless there is differences in the .X loaders and/or .X files used...

If you want anothere set of eyes ...

MView - this utility comes with DX SDK?

Wondering, may be I'll send you not all modified files from Irrlicht.
Scene must look something like that:
