Randomizing the color values on the vertices does have an affect. Is there a switch somewhere to tell the system to use the material color, not the vertex color?

I'm trying to modify the AmbientColor, DiffuseColor, etc with the Direct3D9 version, but it doesn't seem to have any affect at all on the final scene. Even setting the values to 0,0,0,0 didn't change the model to pure black.

Altering the light parameters does have an affect though. Does this sound ...

UPDATE - With the new 1.4 beta the light attenuation is just what I needed. The default values match exactly my needs, and the attenuation factors are now exposed so I can modify them if needed.

Big thank you!

I'm trying to draw triangles with alpha blending. However, it doesn't seem that the approach I'm trying to take isn't supported:

final alpha = texture alpha x vertex alpha

There are two material options which do each one separately, but don't modulate them together. EMT_TRANSPARENT_ALPHA_CHANNEL ...

Awesome news. That's very well timed. When will the next official release occur?

Is it possible to procedurally control an animated mesh scene node's skeleton/pose? I'm working on some stuff that will involve procedural animation, blending, and ultimately ragdoll. The complication is that I can't seem to find any references to accessing the bones/skeleton/pose of the animated ...

Don't worry about having to harness the Cells. One step at a time, and getting Irrlicht running on PS3 would be quite an accomplishment. Even without using Cells. Once you have it running, then figure out ways to use the Cell processors.

Always been a #ifndef user. But now that you mention it #pragma once might be faster. For hobby stuff, I only ever use VS for Windows so might as well gradually switch.

On a side note, I've made it a habit to use

#pragma comment( lib, "mylib.lib" )

Instead of adding files to the .vcproj. Makes ...

I'll check for default values in D3D then. My impression when I first saw those numbers (the default values are probably ever since...) was that these are better suited for interactive scenes where you can walk through. Since the light intensity does not change with the default values it's not ...

That's cool. I look forward to the next release.

I would have expected default values of


light.Attenuation0 = 1.0f;
light.Attenuation1 = 0.0f;
light.Attenuation2 = 0.0f;


Those are the system defaults (atleast for OpenGL) and most commonly used values.

Here's what my scene looks like after ...

I'm running into the same binary lighting issue, see here:

http://irrlicht.sourceforge.net/phpBB2/ ... hp?t=19544

are your normals normalized? if they have a length of anything other than 1.0 then you'll have lighting problems.
you can either recalculate them with the mesh manipulator, or if you want to keep their direction you can set the normalize normals SMaterial flag and let the hardware fix them.
If ...

I'm trying to get a point light to illuminate my scene correctly. However, the light is oversaturated on the lit side. So that the vertices are either super bright, or not lit at all.

There spheres each have 512 triangles so there should be a smooth gradient. And you should see some color ...

Make sure you enable the stencil buffer.
I just had that one catch me. Then,
