Re: Black light?

[Chris Marshall <chris.marshall(at)eclipsecreative.co.uk>]

I find I'm going out of the limits frequently, especially on lights. What would be useful is a slider that allows you to type the min and max values in. Taking that one step further would be to have a mid value as well, so the range goes from 0 to 1 in the left half of the slider, and (for example) 1 to 100 on the right. This would give subtle control in the small values, as well as larger values if required, all on the one slider. It would be like the gradient tool, but numbers rather than colours.

as a rule you should always try and push sliders beyond the visible limit, lots of cool effects to be had there

That’s it! Thanks, Nick. (well, the specular disappears but… L)

 

Never had thought of sliding the sliders to anything beyond visible.

I never got to like that feature where you can go beyond to and from the actual boundary.

If you can do it, why not be more easier to get to it?

 

Thanks anyways.

You can, push the colour into negative values... The trouble is, you may end up with negative values if you're rendering to float and compers won't like you much, so make sure you clamp the surface shaders output value or do a clamp on the final images...

to add a black light (spot or point)?

I want to light up the whole scene with dark spots in certain places.

I can use an object as a shadow but can't we have a black light? J

 

Thanks,
