Animated Emission Map

#1

Hi.

I try to create fire, moving over a peace of paper.
So i created an animation for my surface and linked it to the emission density map.
I also put the texture on the surface to be sure everything works well.

But now, when i try to calculate the animation, its only emitting from the first frame…
But when I skip through the timeline it jumps to the correct emission frame.
[VIMEO]90030431[/VIMEO]

I tried different image sequences but nothing works.

I went through die guid and searched in forums but i can’t find a solution, in the end it will be just a simple setting i missed.

Try two things.
Make eg a polyPlane and assign the same fileNode and turn on texturing in the viewport to force updating the file.
Another thing is to create a scriptNode that is set to update every frame.
Something like:
setAttr -type “string” fileNode.fileTextureName “sourceimages/myMap.iff”;
