Octane render experiments

[whersmy]

Thanks elska! Funny I always just set SR to 10k, but tweaking might help.

I did notice some colour difference in the passes. I think I read somewhere that`s a bug, but not sure.
The main pass differs in colour from the denoised pass.

Incremental values of 1 should suffice, if there are 2 lights and the second light requires a higher sampling priority (what Sampling Rate does in very short), a Sampling Rate value of 2 should suffice.

I believe it has been reported in the forum already. I remember seeing it but I would recommend to double check via the forum-search bar about it. It might even have been fixed in a 2021.1 RC build, that is also to verify as I am not entirely certain.

Will look into it

Trying out different lighting. Also gonna test out the random tiles script this week

[whersmy]

Another one with the lamp turned on. Really like how subtle ACES and 16-bit EXR`s give control on lighting.

Seems like the partition / random tiles generator script works nice. A very basic setup already really convinces. Here`s the node-setup. Will do a more random example in the upcoming days. Really digging the 3080 and stability of 2021.1 XB1! After three days 0 crashes yet when using textures over 10k x 3k pixels, Universal materials, LUA scripts, ACES and 8K HDRI`s.

Getting the random tiles for the floor a bit more decent. Also reset the up-vector so the camera is correct again.

Another try-out for more soft light and post-pro in PS with ACES.

[whersmy]

Trying out direct sunlight. Coming from a 1060GTX to a 3080 is just the best!

And one with more diffuse light. About 1.5 hours on a 3080. It seems the universal material (on this scene f.e. wood) with mix textures, invert textures and color correction nodes do take way longer to clean up, without any real visual difference. Gonna optimize the scene further.

Edit: attached a version saved as 8-bit from 16-bit. It looks like contrast and depth is lost when saving as jpeg directly from 16-bit in PS

A few more shots. Next up is optimizing the scene. Theres a baked OSL Random texture on the displacement on the cloth. Universal material with the layered options on the ceramic pot. Lit by 1 HDRI. Used ACES again with some curves adjustment.
