Blender + Embergen: How To Setup Simulations Properly

How to combine properly Blender and Embergen for making amazing simulations scenes with realtime fire / explosions / smoke.
Wanted to make some Ghost Rider since a very long time (really, that character is too much underrated globally).

So 60hz and famestride 2 works for 24/25/30fps Blender sequences then? I don't undestand why this is better than changing the entire sequence in Embergen to work natively with your Blender sequence. I mean there are no sync problems later? So for 24fps shouldn't it be 48hz for embergen simulation and frame stride 2? I don't understand

[@RaffoVFX]

I suggest: regardless of having 24, 25, or 30 fps, override to 30 fps and export a framestride of 2 like in the video. Doing as you say (no override, 24 fps, 48 hz, framestride 2), is technically correct but is potentially gonna break up completely the simulation in Embergen (too fast explosions, explosions not happening at all, stuff like that). Btw if broken simulation must happen, you already see it happening in Embergen, so trying costs nothing.

[@samu7015]

@@RaffoVFX I did try lowering to 24hz and indeed things go very fast and such. I guess it requires adjusting the values in Embergen to match previous speed and so on. I'm just curious as to what it does to the fluidity of the sim with your method, in your experience. Like why doing it like that is the way to go, despite the framerate not matching exactly I mean.

[@Blazer8496]

Wonderful stuff! Very helpful! I just recently joined your Patreon and found exciting tutorials in there. I was wondering if I could find the Ghost Rider animation in a Blender file somewhere in there if it's something you are willing to provide. I'm not sure if you already have it there and I missed it. Really appreciate your work. Thank you!

[@RaffoVFX]

Thank you:) this project is not available for download, however I usually say it on youtube when related files or tutorials are on patreon:)

[@Blazer8496]

@@RaffoVFX I understand. Thanks for your reply!

[@proden_]

Thank you so much for this simple tutorial! This is what I needed 🥲

[@RaffoVFX]

you are welcome:)

[@simonmarlofabillaran509]

What a superb tutorial! By the way, is there any solution we can make to expand the "bounding box" or the domain or I don't know what's the right term for that ( Hahaha), so that you can simulate a long smoke trail?

[@RaffoVFX]

thank you! check the simulation node options!

[@charithevfx]

can you please explain the shader setup of this simulation in blender ( Fire + smoke shader , ember gen to blender )

[@RaffoVFX]

For the fire I use the shader made by Christopher Fraser, its really easy to tweak, check it here blendermarket.com/products/pyro

[@zacharytarantelli1383]

You didn't talk about shading though...

[@eternal.incorpated]

you did gloss over the issue im having with transforms

[@gediongodfrey]

Is this also on your patreon?

[@RaffoVFX]

no, I believe KZbin has already millions of video about character animations. My Patreon is mostly about destruction stuff, vfx, simulations and compositing on real footages, personal teaching, stuff like that

[@Raitan2008]

will this same process work in Unreal Engine as well?

[@RaffoVFX]

in unreal engine is easier, Janga made a plugin to simplify the importing if I remeber correctly. Ask them about that

[@von.3d]

how is your VDB playing so smoothly? mine just lags when it gets into the middle...

[@RaffoVFX]

check the voxel count of your vdb in embergen, when is too high it will lag in Blender

[@von.3d]

@@RaffoVFX I gotcha. Thanks!

[@von.3d]

@@RaffoVFX Hello again! I used a preset from embergen, a shockwave. it has 33m voxels by default but still lags in the middle. as I've heard from other tutorials, that's too low? I got ryzen 7 5800x3d and a 4070 ti.

[@denizcarta9915]

hello, i could need some help , is it possible to use an imported geometry only as an Effector und not as an Emittor. I want to manipulate an fire emittor with an imported Geometry but the Geometry himself should not burn. but rather it should effect the emittor with his geometry, i hope this was clear, my english is ugly sorry, , sadly i cant find an option like that. In Blender forexample, when you start a simulation, you can us an Geometry as an Effector inside the Domain Box. I really need this Option in Embergen. Someone can help pls ?

[@agingmirror4524]

i found out by myself, you must give the emitter and the geometry two different Emitter Volume und turn off smoke and flue inside the emitter Volume of the geometry ❤❤❤❤ after 8 hours ❤❤❤😂

[@l33f1]

how can i get mroe FPS

[@RaffoVFX]

most of the time its all about optimizing your simulation setup. A part from that, of course a nice gpu is required for embergen

[@user-zd7cq8xq7y]

can you make car drifting smoke in embergen ? and blender and workflow ?
