hello,
I'm using a texture rate emission on a nurbs plane, controlled with an image sequence. The outputColor of the file is connected to the textureRate attribute of the emitter. My files have a very small area of white color, so that I have to increase the global emitter rate to 50 000 000 part/s to have a good result.
But by this way, the playing is getting very very slow, even if the total count of particles doesn't exceed 20 000.
I decided to try another method to inprove the calculating time, by reducing the global rate, and plug a multiplyDivide node between the fileOutColor and the emitterTextureRate. The result is that I have mutch more particles and the playing is fast.
BUT changing the input2 values dosn't affect in any way the rate! This is a very strange result!
My questions are :
1/Why is it faster to calculate with this additionnal node?
2/Why doesn't I have any control on the rate when I try to incrase or decrease the input2 value?
