Hi Michael,
Hi.
Currently I have a forward pass fragment shader (
https://github.com/OGStudio/editor/blob/master/pipeline/pass1.frag )
with uniforms "useNormalMap", "useGlowMap" which define if certain
draw buffers should be filled with bumps and glows.
I provide those uniforms with
NODE->getOrCreateStateSet()->addUniform(), it works perfectly fine.
I also have a deferred pass fragment shader (
https://github.com/OGStudio/editor/blob/master/pipeline/pass2.frag )
with uniforms that I provide with
PASS->getOrCreateStateSet()->addUniform(), it works perfectly fine.
Now I tried to provide a new uniform to the deferred pass fragment
shader with NODE->getOrCreateStateSet()->addUniform(), and it does not
work. Only PASS approach works for the deferred pass fragment shader.
Is it possible to pass uniform value from the NODE's StateSet to the
deferred pass fragment shader? Am I missing something?
You can set the uniform to the Camera node for the pass to make it per
pass. If you set the uniform down in the camera's subgraph at node-level
and you don't use OVERRIDE or PROTECTED in between the node's uniform
should overwrite the state above. In your case it should simply work.
I personally usually use the pragmatic shader composition for things
like normal-mapping etc. since it is static for the given mesh and will
work pretty well if you have nodes in different passes. So basically you
set the shader program to the pass-camera and set the defines per node.
Cheers
Sebastian
Thanks.
