Some shaders fail to load, if using procedural textures.

[Zarkow]

Ok, so here is a snippet from a log-file:

Code:

As we can see two shaders fail to load fully, both with references to failure to load/create procedural textures in the included helper-files. The files themselfs are being loaded, so don't be tricked by the error message, but the creation errors out with a memory-ref as we can see. Tested on both 6200 and a 7800-card, so it's not gfx-card memory per say that is too small or such.

What could this error be from and how to solve it?

error X1507: failed to open source file: 'include\\Quad.fxh'
error X1507: failed to open source file: 'include\\stripe_tex.fxh'

Seems like you need to put those files in relative folder 'include' to shader you're trying to load.

[Zarkow]

As I said, that should not be the problem. The error is on the line before, the 'not loaded' is the EFFECT of the failure.

The line if the file didn't exist would be:

Code:

05-19-2008 19:45:24 | SHADER MANAGER : Error : D:\Borland\Delphi7\Projects\Nvlf_RenderTechTest\Test.1\data\shaders\durer.fx(40): error X1507: failed to open source file: 'D:\Borland\Delphi7\Projects\Nvlf_RenderTechTest\Test.1\data\shaders\include\stripe_tex.fxh'

- Note for admin: one row code-entries doesn't work properly.

(Here I removed the file.)

However, if I move the files from the include-subfolder that nvidia likes to use the files are loaded without complaints, but not all shaders are fully working ofc. But it's very odd that the include-paths doesn't work as they should. I'm not on the absolute latest release, so is this something that has been fixed?

[Zarkow]

So if anyone is unsure of the issue: Any relative path in the shader in load referencing other shader files would fail on load in TV3D6.5.

This is no doubt a TV3D6.5 issue however.

If you put all the files the shader needs in the same folder as the shader, it should work. This is the refered method because not everyone has the nvidia sdk installed, the so shader would not work on their systems if you referenced everything from the NVidia's Include folder.
About the shaders still not working fully: You'll have to revise the shaders as TV3D does not work exactly the same way as Nvidis FX Composer.
