I need to apply a custom shader to each dynamically created object, as I am passing specific parameter values to each one.
I only need the shader temporarily, but there's no obvious way to delete shaders, so I will be leaking some memory at the very least.

I am using LoadShaderFromString() for each object and the object which the shader applies to will be removed after a couple of seconds.

Yes I also came across this problem.
The solution is not to load so much different shaders (reuse the shaders with same attributes etc)
Are your shaders very different or can you change the parameters via uniform variable or combine some shaders ?

It's the same shader with variables.

However, each object has to have it's own shader or the same variable value will affect all objects.
I suppose I could use a shader stack to rotate them...

@Paul Johnston: Great thanks

@nz0: Did you consider using: SetObjectShaderConstantByName()

^ oh yea..

Didn't see that.
It will help me having to keep generating new shaders on the fly.
