Hey all,
I've been making my way through various render engines for c4d in an ever-ending search for somewhat reasonable render times for a scene/model I use a lot.

Im on a Mac Pro 2019 16 core with W5700x 16GB and 160GB Ram. So limited enough hardware for the 3d world.

I had C4dtoA down to about 12min per complex frame and have been getting my head around Octane recently to see if I can improve on this. The recent addition of AI light seems to have helped significantly but I'm still around 20min a Frame with 10k samples if I want a noise free render.

There are 4 source lightbulbs run through 4 cloners with a shader effecting the emission for an on/off effect.

So I'm hoping some of you far more experienced people than me might be able to help?

Here's a couple of screen shots....





I can share the file but would prefer DM rather than public.

Thanks for your time!

Hi,
please have a look at here:

Thanks Beppe,
Just getting back to this project now!

I think I have this working on my file. Cloned Light bulbs work.

One thing I can't figure out is how to 'turn off' the light emission with an effector/shader.

Apologies if this should be obvious - relatively new to Octane

Thanks

Actually I may have figured it out. Emission set to Blacklight with material set to mograph

Great to hear you have solved

Hint, you can also use the Instance Color node, and use C4D Fields with a Plane Effector to change the emission color from black to whatever you need.

Here is an example with Opacity channel:

Happy GPU rendering,
