Maya Keyframe animation not working in Render/Arnold

[Anonymous]

Hi,

I'm a beginner at Maya, so I learnt the basics and made a candle and put a flame on it with fluids using tutorials. I animated the flame to go from 'fully burning' to fading sequentially and then going out completely, followed by smoke (which was a different fluid and emitter than the one that caused the flame). I made this 10-second animation using key-frames by putting them on the 'Density Scale' attribute of the fluids and lowering it turn by turn with each new Keyframe and slowly bringing it to 0. The animation plays inside of Maya perfectly, using the animation preview next to the time-line.

But, when I render the scene, the flame stays burning and never becomes dimmer like I tried to make it to be and never goes out, and then smoke comes out (from the other emitter) whilst the candle is burning.

I've tried rendering many times using 1080p + JPEG, 720p + PNG but it just doesn't work.

Can someone please help me? I have been searching on Google for hours but cannot find any answers at all.

I would greatly appreciate any kind of help! Thanks alot.

Have you baked/cached Fluid simulation?

Unfortunately that did not work. I just need to know how I can make the same animation that plays as a preview on Maya's timeline, go to Arnold and render in it too.

Thanks for replying. 🙂

Can Rendering>Render>RenderSequence | RenderView>Render>RenderSequence be a solution for your case?

Actually, I've been trying to do Render Sequence this whole time, it's not working.
Also, BTW, I'm so sorry, I thought your signature was your post before, just now realized it's a signature. I'll try to bake/cache.

Edit: I did the Cache thing but it had no visible effect. 😕 Bake seems too difficult and something for simulations and not for keyframes, which is what I'm working with.

Yes, sorry for that. I noticed that my satirical sig blends with the message, which might be misleading; edited. If you happen to delete userPrefs and some valuable settings got lost, you can restore them by exiting Maya, renaming existing userPrefs.mel to userPrefs.old, and restoring deleted userPrefs.mel file from the TrashBin, and then launching Maya again.

Hi!

The Density Scale is simulation parameter.

It also acts as shading parameter for Viewport 2.0 and Maya Software Renderer, but Arnold does not support the shading part.

Use an other attribute to control the visible density, like

Shading -> Transparency

or better control the density at the emitter and set appropriate values for the simulation parameters.

Thank you so much mspeer! I had been totally lost but this was the perfect solution! I'm using Transparency now instead. 🙂

You're amazing though! I was going through these forums before and I've seen the amazing work you do man. Please keep it up, we need more people like you!

Thanks, thanks, thanks!
