Hi to all
How do you test shaders if they were made by python?
Can we put shader(pre-registered skeleton) in texture slot in real-time?
Can somebody explain how to work or specifications for/with physical renderer and embree from maxon devs?
(I'm blind and did not find info 
)

1. Do NOT write shaders in Python everything except from def Output(**kwrgs) : return cd.p will be fricking ** _ _** ** slow**. I have written a noise shader and a uv-grid shader and both are sooooo slow.
2.Not sure what you mean by real-time. You can reload a shader plugin like every other python plugin. In some scenarios you will have to reassign the shader to the material, but if you just change moo = 5+i to moo = i^5 you can reload and rerender without any further steps.
3. I am not aware of any access to these features in python, I would be surprised if it is the case. But on the other hand I am often surprised ;)

Hi,
I might have misunderstood your posting a bit, as the topic is "testing of shaders". For testing
python is fine or actually perfect. I did fixate a bit on your seemingly performance related question
regarding embree and pr.
so long story short : testing some sort of shader code - good idea, expecting anything close to
the usual shader performance or even production ready - won't happen.
happy rendering,
