Profiling shaders (rough shader complexity estimation)
Hello there, is there a way to profile shaderlab's shaders? I'm not looking for anything specific or accurate, I would like to have a generic idea of the complexity of a shader. What I would like to achieve is something similar to the shader complexity in the unreal engine. Here is a link: https://docs.unrealengine.com/latest/INT/Engine/UI/LevelEditor/Viewports/ViewModes/index.html#shadercomplexity
Do you have any suggestions to get a similar result? Thank you!
$$anonymous$$aybe using the unity profiler could be useful or if you know any external tool to profile shaderlab shaders? Thank you!
Hi, would instruction count be a good measurement of complexity? Here is a link to show how to get that info. Maybe you could also set up a scene with just one object/example of your shader in it and use the profiler to analyse that. I suppose you could also use PIX to profile. We're not at that stage at the moment, so this is a just a quick suggestion as to what we would try first =P Hope that helps =)
No problem. Could you mark this as your selected answer? =D
Hi, I released a tool similar to the one you have there in the link to Unreal. You can get it from Unity's Asset Store here. Let me know if you need a particular visualizer added and I'll see if it can be done.
The industry-standard tool for debugging shaders and graphic issues is RenderDoc. It does take a little time to learn, but it's powerful, free and integrates into Unity natively - instructions here: https://docs.unity3d.com/Manual/RenderDocIntegration.html
