The link doesn't seam to work, it takes you to an upload page, not to download the rar file.

If you have just started with TV3D i would suggest doing something other
than shaders, these are quite difficult, i myself feel i'm only just ready to learn
this part of this great system.

Not all shaders will work instantly they all need a little work. however there is quite
alot of help for them.

Can you post your shader and we will take a look. Not myself as i'm just learning, but someone with more experience will be able to help. I will gladly take a look myself but i
can't debug shaders that well yet, i will give it a try though for good practice.

Have a look on the Truevision3D wiki site at Zaks shader tutorial it is the best place to start. I have also lernt from this site to create the demo at Page 5 of that tutorial.

Hope you enjoy Truevision as much as we do.

No,i little know shaders,this shader worked at other engine.And shader in the TV3D samples don't worked too.

Thanks,

 I have had a look at your .fx files from the project and they
all work fine with my shader demo. so the problem lies somewhere
else either the code that creates the shader the mesh you are using
or maybe the graphics card. le me know which graphics card you got please.

I am unable to open your VC++ project.
Which development environment do you use? VS2005/8,VC++, etc

Let me know and i will check the code for you.

I'm looked shader sample,but him on C# =(
I use VS Express 2008 C++

graphics card?then it is bug?at me latest drivers.maybe because of win vista?

[Lyrical]

Hi,
 I will download VS2008 express and see what i can do for you.

i can't say definatly its your graphics card as i don't know the specs
if you look on the web for your card and make sure it takes vertex and pixel shaders
version 1,2 or even 3 you should be fine

leave it with me i will let you know how i get on.

Hi Darknight,

 i have installed VC2008 express and the project load correctly, however,
the project seams to be missing the file "Template.rc" as this is being report missing by the compiler.

I will look through the code anyway to see if i can see anything but would be nice if you could see if you have this file as post a link.

Thanks

[DarkKnight]

Hm.at me project compile without Template.rc.

You can write shader example on C++?

full version,with template.rc,log,exe:

Hi,
   I have fixed the problem for you.

The main problem was the paths to the FX file.

I have updated 3 line for you and i have marked them with //Lyrical so you can quickly find them.

strcpy actually adds the additional paths together recreating the variable.

Code:

AppPath(path,srchpath);

this produced a string of

"c:\Documents and Settings\Lyrical\Desktop\f_u_l_l\Debug\"

when you use this

Code:

pTV->SetDebugFile(strcat(srchpath, "\\debugfile.txt"));

you actually end up with srchpath being

"c:\Documents and Settings\Lyrical\Desktop\f_u_l_l\Debug\\debugfile.txt"

when you came to use this file with the shader the path to the shader became
"c:\Documents and Settings\Lyrical\Desktop\f_u_l_l\Debug\\debugfile.txt\\FX\First.fx"

also the strcpy function made srchpath also point to this path.

NOTE:
You will need to move the FX folder into the DEBUG folder should you wish to use your version of this code.

I have added the full working source here for you

Glad to help

Enjoy Truevision
