Another user and I have tested with some HLSL examples including VS/PS in and output semantics. It seems 3dgs doesn't support the following semantics:

: VFACE
: VPOS
: WORLDVIEWPROJECTION
: DIFFUSE

Those last two are a part of DXSAS which is part of D3DX effect files framework. Don't know if that is one of the reasons but I just wanted to check why it isn't supported.

Thanks in progress

matWorldViewProj definatly works

Not sure about diffuse, but it looks like someone used it as a label.

vFace & vPos I've seen in the reference, but never in a shader. So I'm not sure of it's use and I don't think GS supports it...

I meant they might have used it as:

float4x4 matWorldViewProj : WORLDVIEWPROJ;
texture entSkin1 : DIFFUSE;

So you could further use DIFFUSE & WORLDVIEWPROJ if the inputs (entSkin1, ..) changed...

Oke, I understand you point now but it's the problem of using ': WORLDVIEWPROJ'
with any other matrix which is used as uniform input data. For diffuse, I haven't checked it with a texture yet but with an example of this sort the problem occurs:
Code:

---

float4 testcolor : DIFFUSE;

---

But I'm waiting for a clear answer from jcl or Doug who might explain it ^^

Any ideas ??

Semantics are used in a shader just as shown in the example by xxxGuitar511.

The rendering engine passes vertices to the shader. The five semantics POSITION, NORMAL, TEXCOORD0..TEXCOORD2 are automatically assigned to the 5 components of the vertex structs. All further semantics are unassigned by default. It is up to you to assign and use them in the shader if you want.

I actually know what semantics do but thanks for clearing up
But the question was if the following semantics are supported by 3dgs ??

: VFACE
: VPOS
: WORLDVIEWPROJECTION
: DIFFUSE

WORLDVIEWPROJECTION works with matWorldViewProj but I wonder if it does work with other uniform input data ?? The same counts for the rest of those semantics.

Thanks in progress

we meant all of them (except for the dx10 stuff, obviously):

and these uniform input semantics (sorry, the site is broken the time i post this: right click and view source of the xml file, there's a list with the semantics). exclude the fx composer only stuff (marked with a comment):

I am still not sure if you understood my response. Semantics are not "supported by 3DGS", they are a shader element and part of the HLSL. Of course you can use all the semantics that you listed. You just need to declare them in your shader code.

You can find an explanation of semantics and many examples in the DirectX documentation.
