Hi @eproasim,
Clustered lighting shaders are quite a lot larger than the old lighting system and this likely results in slower load times. It is possible we are including clustered lighting shaders when it shouldn’t, we’ll continue investigating.
Can you disable clustered lighting in your projects for now?
Thanks!
Thanks for letting me know! Clustered lighting has been disabled for now.
Hi slimbuck, I appreciate your help with this. I tried to deactivate the Clustered lighting, but the problem continues, there is something with the shaders. I’m going to prepare a simplified version of my project and I’d really appreciate it if you could give me a hand to fix the bugs. Thank you
Here is a small repro. Thank you in advance!
I want to report some differences that I find from one version to another and that I think have nothing to do with custom shaders.
If we hide the skybox in the camera
or if you hide it in the layers
in version 1.54, everything works normal
but in 1.55, it loses all reflections
Another thing I don’t understand is simply switching between one version and another, without any kind of custom hader, because there is so much difference in the render result. Again I have verified that it is due to the amount of reflection configured in the material
1.54
1.55
here the link to the project
Hi LeXXik,
Reflections now respect specular lighting - just set specular to white!
Thanks
Hi @MLB,
Just to give you a quick update - we’re investigating the difference here. Will keep you updated.
Thanks!
Hello @MLB,
This problem can be addressed by setting the Index of Refraction to be 0.667, which will be treated as a specular fresnel factor of 0.04. The specular change added that IOR participates in the calculation of specularity, that’s why you’re seeing this change 
Thanks,
Gustav
I’ve seen some updates in the examples, some of them are performing extremely bad in my laptop.
For reference, playcanvas 1.55.0, resolution 1080p, CPU i7-9750H and GPU RTX 2080:
The swimming pool example also performed very bad weeks ago, but I took it as a working in progress. Now that the plan is to more 1.55 from candidate to current in a couple of weeks, I wonder if I’m doing something wrong.
Thinking most likely your laptop is using the integrated GPU instead of the discreet Nvidia GPU.
Still those times are super slow, @mvaligursky may be able to comment on that.
Can you try adding the following line before app.start() in the examples browser and check times again please?
app.scene.clusteredLightingEnabled = false;
Thanks for your feedback, this worked very well.
I still have the skybox thing, when I hide it or remove it from the camera, it no longer works on reflections. It was very useful in the previous version, to be able to hide the skybox, and that the reflections still work. What will happen to this?
Sorry to bother you again for benchmarking, can you run these examples and compare 1.54.1 and 1.55.X please as your laptop has issues:
No problem
1.54:
1.55:
Just curious about the reasons to use spot light for the scene, instead of directional? Do we only see a small part of the scene?
If you only use directional, and there are no omni / spot lights, the clustered lighting code should not be added to shaders. I’ll investigate this.
