TurbulenceFD & Octane Volume

[jabbathekid]

I saw this being done in the alpha release thread for V3 last year, though I can't seem to get it to work. I'm trying to render simulations made with turbulence in octane (c4d). I've attached a screenshot of a fast setup I made to show the issue. Thing's i've done are outlined in red. As you can see nothing is rendering in the live viewer.

I've applied an octane object tag to the turbulence container object, i've played with the density, volume step length, is there something i've missed? If it makes any difference im using the learning edition - could this be the issue?

Yes I suppose that tfd api is disabled for non-commercial versions. Test on octane TFD sample scenes.

I tried the same thing with two sample scenes that I got from the v3 alpha thread, but the same issue still arose. o it;s probably to do with it being a learning license? it would make sense

I have a full version of TFD but still having a problem with Octane 3 + TurbulenceFD render.
In render it doesn't look even close to what aoktar published recently. not sure how to fix it. standard render (at this point) renders smoke + flame better. probably there's some settings need to be changed. idk.

I don't know what you mean. Why don't check sample scenes?

I tried. Here's the sample


it's the same scene withouth changes you published here


I didn't change any settings, just cached simulation.
smoke is in the scene but almost none. I tried to push thickness didn't work, dropped brightness didn't work.
not sure what else can I do to bring some volume in the smoke, make it visible.

Add a brighter background maybe?

[petrpolyakov]

brightness of the background wasn't a case but I tried it anyway and unfortunately it didn't work out.

[aoktar]

Here is some explanations. Samples works on me. Try to play with parameters accordingly this information.

[petrpolyakov]

well, I tried to work with the settings and built a new scene with a different parameters
so, here's result in regular standard c4d render


in additional to the explosion I built I added a light source on the left to give nice shadows to the smoke. I think looks great.



here's same scene with octane 3 render. I played with volume medium and got a bit more defined smoke but no volume as in standard render yet (light won't really affect smoke and won't give additional shadows on the surface), looks like some type of dirt (smoke). not bad but original standard render still a bit better.

if someone wants to continue experiments and maybe offer better solution please join

here's a link to c4d scene (if anyone wants to use it for any design purposes go ahead, no restrictions)
