Hi, I simulated an explosion from fireball preset with disabled smoke to render just fire but mantra keeps rendering black frames.I tried to setup everything like it is in smoleless flame but no success.I think I forgot to do something because fire look different in viewport while simulating smokeless flame.Please help.Thanks.

Hey,
just to make sure:
Did you turn of smke emitting during simulation, because that wont work…

If you did simulate with smoke on:
Which Shader are you using?
On the Pyro2 there is a match Viewport Button in on of the later tabs.

Otherwise, please add a file.

You can find the Shader in the SHOP Net.
If it is the Pyro Shader, which it should be default, it may be called “fireball”

In the Utils Tab There you can apply transfers from Visualization to Pyro.

Took a look.

So yeah, something is off with your fireball shader.
Just create a new one and add it to the explosion. This will render fine

I am able to render the fire only in your scene, if I set the Smoke Field/Final Scale to 0

using H15.0.313

most likely it is due to the colorspace

when you look at it in mplay, a gamma of 2.2 is being applied.

this is not baked into the render, unless you set

Images/Output/Gamma to 2.2

on the rop

it may look overbright if you open it in mplay as it would likely put the gamma on as well..so you would set the mplay gamma to 1 when viewing the resulting render
