Underexposing issue in Superfly?



  • No, there is a problem with underexposure. I noticed it with a huge interior scene with several rooms. The scene had around 50 lights. Most of them not visible as they where placed in the other rooms. Increasing the light intensity for the lights placed in the room the camera was in did not help. The render was still to dark and looked somewhat washed out. Only solution was to switch off all the invisible lights from the other rooms.



  • Set the 'clamp' option for both direct and indirect light to 0. That will give you the true brightness, at the sideeffect of possibly more noise.

    = too few samples
    or too few bounces (there is a reason why Blender "full GI" preset has 256 diffuse and 256 specular. Speaking of other pathtracers, Octane has something like 8/16 as default. For simple (one-room) interiors scenes in Lux 8-16 is optimal too. Default Poser values are good only for direct light scenes with a small number of lights. )
    If it was underexposure, increasing light brightness would help.

    Yeah i think thats it.



  • Another trick you could try is to simply turn off the shadows for the walls of the room, or at least dial them down a bit in the properties tab. Might even speed up the render a bit.



  • @eclark1849 No,no, no, no. Might as well render using Poser 4 if you're going to shut off cast shadows from stuff that HAS to cast shadows for the scene to look normal.



  • @ghostship You can dial them down Ghostship. That is why they're there you know.



  • Pretty sure Superfly doesn't let you adjust the shadow intensity. Shadows are either on or off in Superfly.

    Oh wow, this was it. That solved the issue completely!

    What exactly are those two settings for? It says that anything other than zero will show full luminosity but it seems to do the exact opposite at the default setting of 10.



  • I read those tool hints wrong, I finally understood what it meant by clamping. I set it to a much higher number than the default for indirect lighting and left direct at 0. It's grainy for sure at 75 samples, but I can always bump that up and the lighting looks the way I want it to.
