Components problem

Hi.

I use the Hydrax 0.5.4 / OpenGLRenderer and found a bug: when I try to disable some unnecessary component throws an exception.

Components=Sun|Foam|Depth|Caustics : All is well.

Any ideas?

Hi!

Yeah, I didn't test all the modules (desactivating it), so this type of problems could exist.

The problem is the next:

- MaterialManager.cpp builds the shaders source codes with needed uniform variables (inputs into the GPU from the CPU).
- When the shaders are built and compiled, MaterialManager sends all the uniforms variables values.
- If a uniform variable is not needed (so no declared into the shader), but MaterialManager try to send it, error is reported (and program stopped).

I will try to solve it as soon as posible.

Thanks for the report!

Twice problems must be solved! Look for the new version into the wiki page.

Also the Ubuntu packages has been updated to Ubuntu Natty Narwhal

Enjoy it!
