Hello Artists,
i hope you can help me with my problem. I made some smoke simulations, inspired by Gottfried Hoffmann from the Blender Institute(btw thanks buddy), and it always flickers.
Here are some quick renders of my projekt.
The first picture shows the render result, the second shows only the part that is too bright and the last shows the next frame, which is normal.
Now this is one big error, but there are a lot of small ones. The smoke looks like a cloud with flashes in it.
Do you need more information? Maybe you know the problem already?
Thanks!
No one here who can help me? No Idea?
(As you may well have guessed, your inquiry was overlooked. It happens. Good “bump.”)
Well, are you doing this in a linear color space? I am not familiar, of course, with how you do your math. If you render the sim to an OpenEXR/MultiLayer file, you can then examine the RGB values, which can now easily exceed the range [0.0 … 1.0].
There are several nodes which can adjust the output values for a range of inputs, and a “Normalize” node is available and so on. But the place to begin is to determine the actual numeric range of the simulation function’s outputs in all channels: R, G, B, A, etc.
