Irrlicht Engine

I ended up parsing the file myself, i created a preprocessed version of the file with
which handles all the includes and macro's.

you then pass this new version to
which gives you the parameter names to help parsing the file.

Autodesk in their wisdom have deprecated IGameFX and all it's accompanying classes... which meaning I need to rewrite some legacy code in an exporter (if we want to use it in newer versions of max). Now I can duplicate most of the stuff using direct3d sdk function
D3DXCreateEffectCompilerFromFile ...

yep I've seen that, i'm not animating the object and using a directional light, I was really after a yes or no.

but for what it's worth this would be the glsl shader equivalent to what I'm doing in max with hlsl shader (which works entirely as expected)

.vert
uniform int light;

varying vec3 ...

out of interest has anyone managed to create one for irrlicht ? Though I've got a perfectly good tangent space version I was looking to get one working but it doesn't seem to be working correctly. The map is create in max and the fx shader I use in max works well but trying to replicate that in GLSL ...

the only issue with setting it as background object (ESNRP_SKY_BOX) is you have to manually set the draw order but as they are always supposed to be in the background this should not cause any draw problems.... I have a custom background mesh object that registers it's self as ESNRP_SKY_BOX to ...

is your transparent star field object registered as a ESNRP_SKY_BOX ? I use this type for my custom sky dome with transparency. Just means it will always be rendered first negating any sorting issues.

I know, it's just an example to show where alpha sorting can never work.

Yeah, that or you have to write your own custom nodes which do their own sorting I guess.

it's not a problem that can always be solved with code (and a common one in games). for example doing an alpha sort on a crossing tree, as a single mesh or two seperate scene nodes, which face/node is in ...

nice article

i've gone for point & none = no filtering
linear = Bilinear
Anisotropic = Bilinear + Anisotropic
and
pyramidalquad = Trilinear

what's the best match between the hlsl sampler state setting and irrlichs texturelayer setting where the hlsl values
are { none, point, linear, anisotropic, pyramidalquad, gaussianquad } ?

just ignore me

the classic one is as it happens the chain link fence, the obvious solution is to use Alpharef but that can moire like a bitch so you try a semi transparent material, looks good doesn't moire nice; but for efficiency you 'd like nice long strips but now you have sorting issue with other transparent ...

I'm surprised that a special development is needed because we see quite often in games semi-transparent objects such as cars or even wire fencing..

I've worked on many games and one of the biggest headaches is always alpha sorting.
