A Few FumeFx Question

#1

Hi everyone,i have a few question that i wonder the answer.My first question : I realised when i increased the simulation step like 1 to 5,result seems like much more realistic than normal(value 1),why is happening like that?Second question : I created a mountain with dreamscape terra and simulated a bomb but when i rendered my bomb doesnt appear in the render but at the same frame i can see it in the fumefx preview window,what can be caused?Thx.

Hi again,when i turned my terra as render as geometry it worked but now its too hard to work in viewport because of the segment of terra.Can anyone give me a trick to fix it,solution?Disappearing terra seems fine at first but it doesnt change the free memory.

Hi bariscan90

Your simulation is more realistic with step set to 5 because Fume calculates the simulation 5 times by frame. So the simulation is 5 times longer but also a lot more accurate.

for your render problem, I do not know dreamscape but You’ve got to make sure, in your render settings, to be using the scanline renderer and not mental ray. Mental ray does not support Fume fx. You could also use Vray wich does.

I hope this answer all your questions

Thank you for great reply,now i understood why its more realistic.I am using vray but it happens again except for making terra as geometry object,when i did that i have to increase the segment to get correct quality like 100 to 800 or 900 and then its getting hard to work on viewport.I just couldnt find a solution for that.Thanks again once cani.

Cani, both MR and Vray support FumeFX, but they don’t support separate FumeFX’s channels.

Hello again,i found the solution without making terra as geometry object.Here it is to have some issue with me,go through to the environment section and delete fusionworks renderer then add fusionwork renderer again and its done,thank you all of you again.I hope this answer fixs your’s problem too. :thumbsup:

Hi again,i am trying to create kind of nucleas bomb and simulation looks good but i noticed you know i need to increase the value of expansion when i did even on 500mb and 4 simulation steps fire and smoke looks so unrealistic,why when we increased the expansion it cause this,does anybody have same problem with me?Please let me know if you are know the answer.Thanks a lot.

Render last frame and show it here.
