SpectorJS - Detect heavy computation in shader

[royibernthal]

I have a shader which is really slow on mobile - is it possible to use SpectorJS or another tool (let's say even on desktop) to find the problematic part of the shader code that is heavy on performance?

I think so as it will show you the code and all parameters. You can edit the shader live so it will help you create a smaller shader (but no profiling unfortunately)

Oh, so I meant profiling  Anything for that?

i like work on heavy shader  if you intersted

Of course  Here's a repro in a PG:

It should be laggy on mobile - if it's not, you can easily add more models in assetsManager.onFinish.

Any ideas for how to improve performance?

In the actual project, textures on mobile are already optimized to 256 instead of 1024, it didn't seem to help.
