Thanks for the tips. I think applying a map or gradient to the light is going to be the way to go. I've never use an IES profile and will look into that as well. On Fri, Sep 28, 2012 at 9:06 AM, Ed Manning wrote: > That would be best, but in the meantime, there is the Shape Attenuation > control

That would be best, but in the meantime, there is the Shape Attenuation control group in the soft_light Attenuation tab... It's not great, but it has helped me a little on occasion. Also, to the OP: if you are not using distance-based attenuation, then you can put a color_exponent node between t

I think a projector shader is definitely the way to go with lights. You can directly control the falloff and colour impurity you want in the spot. Doing it with the basic light controls is always going to be too 'computery'. On 28 September 2012 10:05, Eric Gunther wrote: > I think I misunder

I think I misunderstood. My *guess* is that you could use a photo exposure shader on the camera, but this is a wild guess. :] This is considering one of the other replies about the "white point". I have to mention though, that I did not mean the "spread" control on the light... there is also a

Hello, for a cone angle of 70° you need a spread of 35° if you want it to start from the center. This should work unless the intensity is greater than 1, or you might have other lights burning the "white point" of the spot. Le 28/09/2012 05:05, Byron Nash a écrit : This seems basic but it has

I understand how to change the spread, but it doesn't seem to give predictable or nice falloffs. I've been playing with settings since I wrote that and I wonder if it's related to Color Management. I'm interpreting my source textures as sRGB since they are just jpeg's. I have Color Management turne

Unless I am mistaken, in soft, you select the light and press the b key to go to the controls on the light (not a ppg but in the viewport). Then you just click and drag the edges to change the spot softness. I can't check right now but I think its the "b" key. Actually pretty nice feature. -e O

This seems basic but it has always confounded me. I would like a softer fade from the center of my spot light to the outside of the cone angle. Adjusting the spread seems to make little difference. See the linked photo for an illustration. I don't understand why the falloff does not start at the in
