Lighting & Output Resolution
show user profile  SuperFX
Hi, I'm new to 3DS Max and so excuse my ignorance. I have a scene with several lights and glow effects. I'm achieving a glow effect by creating an architectural material and setting its Luminance value to 300 or so and setting up a Glare camera shader for the output (learned it from a tutorial). At any rate, I managed to get the effect I want by tweaking the various parameters, when I was testing things at the default resolution of 640x480. Now I want to generate the final image at a much higher resolution (3000x3000 pixels or so), and the effect is very different. The glow is much brighter, the lighting is all off, etc. The image *looks* different, beyond the fact that it has a higher resolution. For example if I were to take the higher resolution image and downsample it to 640x480 in Photoshop, I would get a very different looking picture. Like I said, the lighting is very different. I have Final Gather turned on and all the various renderer settings turned up to max quality. Any thoughts on why this is happening? I can try to readjust all the parameters so that I achieve what I got at 640x480 with the final resolution. But this will be very time consuming, and ideally I'd like to achieve an effect that is resolution independent, because I might need to change the resolution again. Thanks for your help! Mohammed

The glare shader is resolution dependent, sadly. You will need to adjust the settings for your higher resolution.

Thanks for the prompt reply. That's too bad, but fortunately it seems like one parameter is mostly responsible for the variation (the spread parameter in the Glare map).
