water shaders in demomaster problem (Cg program too complex)

Scripting Issues
1

Hello,

I’ve been trying to get the water shaders to work in the demomaster app and although the ocean works perfectly everything else related to water results in the error “Cg program too complex for driver”.

I turned off the basic shaders in config.prc (basic-shaders-only #f). Turning on debug messages revealed the following:

  1. When trying to start Water vtf 1 or 2 the last line seems to be stuck in an endless loop, it keeps throwing that line until i kill the process.
  2. It seems to have a bug related to naming jpg’s (Not loading NULL image tmp/cube0_#.jpg)

Can anyone help me further with please?

What kind of graphics card do you have? Are you sure it can support the required shader complexity?

hi drwr,

I have a ati radeon HD 4800 series. I’m pretty sure it can handle them.

4

well, I got same error even with ATI HD5800 graphics card. So I suppose there is some problem with cg compiler and ati cards or something like that.

5

vtf means Vertex Texture Fetching, an advance feature used in the shader. I believe your card may not support it.

6

Vertex Texture Fetching works in gl shader extemly well. So it supproted by graphics card.

7

oic, so all the vtf shader program cannot run on your card.

8

i tried the ogre3d example regarding VTF and that runs just fine on my card. Also GPU caps viewer (ozone3d.net/gpu_caps_viewer/) VTF Demo runs like a charm. This is actually a handy tool to detect whether or not your card has certain capabilities. For example, my card does not have Cuda support (obviously)
